Sell With a Story: Color Pairings That Pop

Think back to the stones that have dominated jewelry center pieces for years past. If you’re like many, you probably immediately thought of the big four stones: diamonds, sapphires, emeralds, and rubies. No one can deny their beauty, but as customers’ tastes evolved, beauty alone isn’t enough.

They want something else. Something with a story. Something no one else has.

One way in which we’ve seen customers exploring this desire for uniqueness is with gemstone combinations that range from bold jewel tones that give the wearer confidence to sunny color unions that invite happiness.

Take it Back to the 1920s

Back in the 1920s, Cartier unveiled a bracelet that utilized an unusual color combination: green, red, blue, and white. Of course, those four colors came from the big four stones themselves — emeralds, rubies, sapphires, and a dash of diamonds — and thus a luxurious line of jewelry was born. Later on, these designs came to be known as Tutti Frutti.

While these shades seem to conflict with one another, Pierre Cartier was clearly onto something: the popularity of this combination has endured in the approximate 100 years that have passed since Tutti Frutti’s introduction. And with the record-breaking $1,300,000 sale of one of these bracelets at Sotheby’s last year, gem-intensive styles have enjoyed a renewed cultural relevance and fanbase.

The 2020 return of Tutti Frutti has opened the door for unique color pairings — and the more they pop, the better.

Blue and Orange

Bright, ornamental designs are trending in a huge way, especially when they combine a matte, opaque stone sitting in contrast beside a translucent faceted gem. Lapis lazuli, malachite, onyx, coral, and turquoise are but a few of the gems that are up for the task.

One of my favorite pairings is in the above image, where the complementary combination of blue and orange lends itself to a striking story of fire and ice.

While you can use a deep blue sapphire for this combination, how about swapping that deep blue gem for the soft blue of turquoise? Mixing textures is a visually interesting way to kick up the fun of any design.

For example, let a faceted orange stone (I suggest the ever-beautiful spessartite garnet) take center stage, and have a halo of turquoise frame it. Accent these designs with a sprinkle of white diamonds, and the result will be a seriously eye-catching design. The contrasting texture of opaque against faceted is one we absolutely adore — and your customers will too!

Pink, Green, and Teal

For younger customers who want to break away from the rubies, emeralds, and sapphires that their grandparents wore, a combination of pink spinel, teal tourmaline, and mint green garnet may strike their fancy.

This tropical combination is a contemporary take on classic red/green/blue designs yet still offers customers an effortless piece they can wear with any outfit. Try experimenting with the balance of colors to see what you like best. The size of the stones, the shapes you use, the metal quality, and so much more give you endless ways to play with this combination.

Of course, you can always try swapping out one of these gemstone colors for another of the same hue or vibrance. For example, what if the pink spinel not working for you? Maybe a yellow sapphire will do the trick.

Sell With a Story: Black Opal

A sunset, tropical waters, watercolor paintings, Holi color clouds, the galaxy. You might be asking, “What do these have in common?”

If you have ever seen an opal, you likely already know. Considered one of the most colorful stones available within the industry, opals show many colors all in one wearable stone.

All About Black Opal

Moody and mysterious, black opals are fitting for an October birthstone. They have a dark body color with a gorgeous play of color that spans the spectrum. The benefit to a dark body color is that the colors pop off the darker background and scream at people to look at them.

Notable Gems Black Opal

The rarest and most valuable type of opal —  black opals —  are found at Lightning Ridge in New South Wales, Australia. No one really knows where Lightning Ridge got its name; however, allegedly a farmer, his trusty four-legged companion, and his flock of sheep were struck by lightning, aiding in the ridge getting its name.

Perhaps that’s fitting. Lightning Ridge black opals can be as dark as midnight with a play of color that’s akin to a night sky lit by bright flashes of lightning.

Technically Speaking

Opals have some technical words that are associated with them and them alone:

  • Play of color: The flashes of color you get when you rock and tilt the stone. This phenomenon is created by the internal structure interacting with light.
  • Body color: The background color, the palette in which all the colorful flashes lie.

At Stuller, we grade our calibrated gemstones based on the darkness of the body color. Gray body color will be graded as AA quality whereas a dark gray or black body results in AAA quality.

Calibrated Opal

Each black opal in Stuller Notable Gems™ is hand selected to represent the best features or a quality that’s unique to that stone, whether that’s body color, pattern, shape, or something else.

What Makes an Opal Valuable?

All other things equal, the play of color and the stone’s pattern determine an opal’s value.

Play of Color

A vibrant red opal has a more expensive price tag as it’s incredibly rare. The more red visible when you tilt and turn the stone, the more expensive the opal. Follow the spectrum backward for values: blue, at the opposite end of the spectrum, is the most common and therefore the least valuable; yellow, in the middle, is valued as such.

Play of color that is visible from one angle or only on part of the surface drops the value of the stone. The play of color should be spread across the whole stone, even if it changes in pattern type.

Notable Gems Opal


It seems strange to think that the pattern of colors on a stone would aid in the value that it holds. However, when you think about it in terms of rarity, it makes more sense. There are three major types of patterns that hold sway on value, each represented by a corresponding look and rarity factor:

  • Pinfire: Very small patches or dots of spectral color.
  • Flash: Large areas of play of color.
  • Harlequin: Large, distinct, usually angular patches of play of color with touching edges.

Harlequin is quite rare, especially when you get a full range of colors, which makes it considerably more valuable. Pinfire is very common, making it less rare and therefore less valuable — even when the pinfire play of color is red.

Opals for October

The extraordinary shapes and unique ability to match and highlight any color makes black opal a go-to for designers wanting to create one-of-a-kind jewelry. The dark palette and eye-catching explosion of color make black opal a customer favorite for those keenly aware of the attention they will get — social media, here they come.

Notable Gems Black Opal

Try having a few loose in your store this month (it is the October birthstone, after all!), and it’s sure to lead to conversations about what black opals are, where they come from, and how customers can add one to their wish list.

At the very least, you get to have a lively, gemstone-positive conversation that can open the door for future questions. And your customers will think of you as the gemstone expert!

Happy selling!

Sell With a Story: Fancy Colored Sapphires

Did you know that Sapphire comes in every color of the rainbow, except red? Every. Single. Color. Plus a few.

Multi-colored Sapphires

Fancy colored Sapphires are all the extraordinary colors outside of traditional blue, colorless, and black. Today, we are going to explore some of the up-and-coming colors as well as some of the most sought after.

Pantone 2019 Color of the Year Padparadscha Sapphire

First up is one of the rarest of the Sapphire family, Padparadscha. Pronounced pod-par-ah’d-sha, this gorgeous and subtle stone named after the reddish-yellow lotus flower is equally controversial as it is rare. Depending on who you speak to, the color defined to be a Pad (pronounced pod) can vary. Here at Stuller, we define this color as representing both pink and orange color within the stone and pale to medium in tone. If you look at the Sapphire and the first thing you think of is that it could have been plucked from a mesmerizing sunset or last night’s salmon dinner, it is likely a Pad. Trending because of the gorgeous color; paired with a pink gold mounting, these stunners can be any, from punk to princess, pink lover’s dream.

Dark Green Sapphires

Next up are cool tone Teal and Green Sapphires. These delicate colors are trending because of the unique and subtle color that packs an earthy punch. Coming from all over the world, teal and green stones can range from dark and broody with a surprising pop of color in the right light to faint, yet somehow bright, green. Stones coming from Montana in the US makes for a unique home-grown aesthetic. The draw to these sophisticated colors is how nicely they play with all metal colors and skin tones. The ethereal natural look lends them to delicate floral inspired mountings or minimalist designs that really let the stones shine.

Purple Sapphires

Purple Sapphires are a durable alternative to amethyst; rich and deep and powerful all rolled up into one easy to wear, durable stone. As a trending color, purple is alive with intensity. Since purple can come in many different shades from violet to reddish, select a cool tone stone to match your platinum mounting and a reddish stone for your yellow mountings to bring out the best in your Purple Sapphire. It’s not unusual for Purple Sapphires to be color change (or color shift in this instance; a sly change from purple to violet blue is what you would be seeing) stones, so make sure to take your stone outside to optimize its color. This is a great sales technique for your customers too if you have the ability to do it — and certainly if you know your customer well.   

Earth to Market Sapphires

Earth to Market Sapphires from Umba River Valley in Tanzania are one of my favorite fancy colored Sapphires right now. They feature a beautiful rich reddish cognac color with flashes of reds, oranges, yellows, browns, maroon, and even greens. This stone is the autumn leaves of New England embodied and are great for a customer that wants something photogenic with a great story. Our Earth to Market stones have known origins and the Sapphires are no exception.

Bicolor Sapphires, sometimes called Parti Sapphires, exhibit more than one color within the same stone. This colorful combination can be any match you can think but are more commonly found in the blue-green-yellow range or the pink-purple-blue range. Generally cut into shapes that are longer to show off a pronounced color line, bicolor Sapphires can come in many shapes and sizes. We have many bicolor Sapphires in our Notable Gems™ collection, including rose cuts and some unusual shapes.

We wrap up with a truly unusual fancy Sapphire, the Trapiche, which looks a little like a 6-spoke wheel with black, white, or grey growth pattern making the spokes and a greyish blue in-between. These unique cabochon or tablet cut stones can be special ordered through our Gemstone Special Orders Service in many different sizes and even as a matched pair for the customer who has everything and is ready for something curiously remarkable. 

I hope reading about some of the lessor known Sapphire colors encourages you to choose one for your next gemstone or bridal customer. They make a great option for a stone that is durable and easy for everyday wear and, of course, a fantastic way to showcase the uniqueness of each couple.

Happy Selling.

Sell With a Story: Imperial Topaz

Topaz crystals are impressive. Some of the largest specimens can weigh hundreds of pounds. The largest faceted stone in the world just happens to be a Topaz: The El-Dorado Topaz weighs in at 31,000 carats (13.6 pounds) and is currently housed in Spain.

Imperial topaz represents less than ½ of one percent of all top-grade topaz. Why, you ask? Because of the red or pinkish orange color found within. Imperial Topaz can be identified by the red cast all over the stone yielding the pinkish orange color or in a dynamic way at just the tips where you have an ombre blend of golden yellow to fiery red. For a particularly fine specimen, the golden color is in the center of the stone and blends to red at the tips. To see one is to understand the intensity and rarity of a stone. Yellow or Golden Topaz as well as Precious Topaz and Pink Topaz are beautiful in their own right but lack the telltale vibrancy of red, which makes them less valuable.

Imperial Topaz is frequently compared to the colors of a setting sun. Imperial Topaz, an 8 on the Mohs scale of hardness, is a good option for everyday wear. The color range that you get from Imperial Topaz lends itself to unique and personalized pieces of jewelry. The more red or vibrant pink they are, the more valuable and rarer they are. Adding to the popularity, the mostly eye-clean crystals can be found in almost every shape known, as well as unusual and fantasy cuts. Having large crystals leaves room for the imagination of what could be cut. And within the stone industry, there is no lack of imagination! A famous Imperial Topaz cut by Kreis in Germany and aptly named The Imperial Flame looks a bit like an elegant bottle of the highest quality champagne.

Value in such a fascinating stone is not only relative to its color, size, and rarity. In the case of Topaz, it’s also relative to its cutter. You read that right, its cutter. Topaz is not easy to cut — just the opposite. It can be a real challenge. Having a lapidary that can wrangle the rough material into a gorgeous, marketable gemstone is an art that few around the world have mastered. Having a reputable source for your stones can mean the difference in a stone that will last a lifetime and a stone that will chip and break easily.

Most Imperial Topaz available today comes from Minas Gerais, Brazil. This has been the source for the last two centuries. Prior to our sources today, the Ural Mountains in Russia produced some of the highest quality and most saturated specimens. Ownership of the highest quality material was limited to Royals.

Known to attract wealth and money and to bring good fortune to those in possession, Imperial Topaz is one of the most popular stones around the world. During the Renaissance, people felt that Imperial Topaz could dispel anger. With such vibrant and bold colors capturing attention and becoming the topic of conversation, I would not doubt it!

Happy Selling. Sam

Downright Playful – Garnets, Moonstones, Chalcedony

And since the same group usually wants something unique but still Instagram worthy, cabochon cut stones in reds, whites, and blues are sure to be a home run, with colorful little bubbles gleaming on their phones.

Pearl Points: Varieties, Characteristics, and How to Sell Them

Pearls—cultured and natural—are experiencing a renaissance in fine jewelry! Thanks to fashion designers who’ve been affixing them to runway creations, jewelry designers who see their creative potential, and consumers who crave uncommon and one-of-a-kind masterpieces with decadent luster, pearls are in a prime position to continue gaining more significance. To that end, consider this primer of key facts to better educate buyers and sell cultured pearls in store.

Pearl Types

The most widely known and available categories of cultured pearls (those grown with man’s help versus ones grown unassisted in the wild) are freshwater, akoya, and South Sea, which include Tahitian, golden, white, and silver pearls. (Cultured pearls represent the bulk of all pearls widely sold in the U.S.)

Freshwater pearls are the most colorful and affordable of all cultured pearls. The color of the lips of freshwater pearl mussels vary widely, from white to pink to lavender, peach, and more. Meanwhile, costs to grow freshwater pearls are less than akoya and South Sea because freshwater mussels are more abundant, and their pearls require less time and maintenance to grow. Freshwater pearls are an ideal entrée item to collecting fine pearl jewelry.

Akoya pearls are known as the Cadillac of pearls for their supreme luster. Slick, high-polish surfaces are the calling card of the akoya pearl, which is grown in the colder waters off the coast of Japan and in some parts of China and Vietnam. Akoya colors—based on the lip color of the oyster in which they grow—are white, off white, pale gray, light blue, and cream with overtones of pink, silver, and green. Akoya pearls are often viewed as a classic choice, though jewelry designers are now taking advantage of the wide range of akoya types on the market.

Tahitian Pearl Mollusks French Polynesia

Finally, South Sea pearls are among the toniest of all of these lustrous gems. South Sea pearls only grow in warmer waters found in French Polynesia (think Tahitian pearls), Australia, Indonesia, and the Philippines. (A variety of black-lipped pearl called the Sea of Cortez also grows in Mexico.) Colors range from black to green to peacock, white, golden, champagne, gray, and more, while growing a single South Sea pearl takes up to two years. Not surprisingly, these pearls tend to cost more than others, depending on quality and size.

Pearl Qualities

Overall, characteristics of pearls are shape, size, color, surface, nacre quality, and luster. In general, the larger and rounder the pearl, the more valuable—with the exception of some larger and unusual baroque pearls. Some colors are rarer than others, too, such as true peacock and golden hues among South Sea pearls and natural colors of pink, lavender, and peach freshwaters, which increases their worth. Smooth, clean surfaces are the ideal in all pearls, though sometimes rare colors can command a premium even if the pearl surface isn’t perfect. Nacre quality refers to thickness—more is considered better—and luster; the more intense the luster, the more valuable the pearl.

Freshwater pearls largely have the lowest luster, though metallic surfaces do occur and are more valuable. Akoyas are known for their luster, while their sizes typically don’t exceed 10 mm, though baby akoya pearls have grown popular in recent years and offer another type of entrée product for their smaller sizes, abundance (several can grow in one oyster), and because they require less growing time. South Sea pearls are known for their thick nacre (because they grow faster in warmer waters), luxurious luster, and large sizes—some exceeding 20 mm!

How to Sell Pearls

It’s easy to sell pearls when you fall for their backstory. Pearls are organic gems—they grow inside living creatures! Akoya pearls are a tradition in Japan—the father of the cultured pearl, Kokichi Mikimoto, was from Japan—while South Sea varieties grow in stunning, remote locations around the world. Water quality must be pristine in order for pearls to grow; a pearl farmer’s reward for good oyster care and clean aquatic conditions is a beautiful pearl. Pearl farming provides countless jobs in far-flung destinations, while all pearl production requires patience and nurturing, just like relationships. No other category offers such a meaningful and parallel experience, from adversity to triumph, to those who wear the product.

And thanks to brilliant design minds, pearl jewelry is as diverse as individual personalities. Pearls can be interpreted into every trend in the market—from station, Y, and layering necklaces to stacking rings and uncommon stud varieties—as well as ones that have yet to debut. And the complex colors of pearls with their body and overtones are as intoxicating as love itself. Understanding the journey of the pearl, from implanted bead or happenstance irritant to a nacreous object of beauty, brings you closer to appreciating their specialness while their thumbprint-like uniqueness is impossible to ignore. The surface beauty of pearls may intrigue you, but the story of their origins and creation is generally what turns passive admirers into full-blown devotees.

Sell With a Story: Spectrolite

Let me introduce you to the dark and broody cousin of Moonstone. When Moonstone is Hairspray, Spectrolite is Phantom of the Opera. When Moonstone is a bright summer day, Spectrolite is a cold dark night lit up by the bewitching northern lights.

Known as the transformation stone, Labradorite (according to legend) fell from the aurora borealis and transformed from the ordinary to the extraordinary on the way down, giving its wearers the same good fortune.


A less common variety of Labradorite feldspar, Spectrolite is identified by a dark body color, usually black or dark gray, with vibrant swaths of flashy color. These flashes are known as labradorescence (Moonstone, by contrast, has adularescence, which is the swath of billowy color atop moonstone; labradorescence is only found in varieties of Labradorite Feldspar). This phenomenon is caused by light interference in the crystal structure and can result in any combination of colors, although more commonly seen in shades of blue, teal, and green – think the soft velvety nature of colorful butterfly wings. Not unlike other feldspars, Spectrolite comes in at a 6.5 on the Mohs scale of hardness and can easily be worn daily with a bit of mindfulness to prevent banging and scratching.

The Spectrolite we know today has been around since the 1940s, with World War II unveiling larger deposits, at that point making it a more prominent stone in the jewelry and gemstone sector.

Generally fashioned into cabochons to help intensify the phenomenon within the stone, it is available in many shapes or outlines and rock forms. Spectrolite originates from Finland and has bright, bold labradorescence.

So how do you sell these natural wonders? Play up the uniqueness and focus on what makes them so special. First and foremost, the flashes of color you get from any one stone is unique to that one stone. The cutting and polishing process add slight alterations to the structure giving each a compelling grid of skeletal elements – think fingerprints – causing the flashes of color to be unique to just the one individual.  Second, the elegant and understated body color, a subtle black, goes seamlessly into everyday wardrobes and is a great conversation starter when the flash of color catches someone’s eye.

If you have not had the opportunity to see a Spectrolite up close I encourage you to seek one out. They have a natural beauty that is not easily defined or captured in images. If you are new to the cabochon scene, worry not, Stuller offers many cabochon mountings as well as our CAD/CAM services that can fit your stone into your exact design.

We want to make sure that our customers have exactly what they are looking for no matter what those needs might be, make sure to check out the Gemstone Special Orders page if you are looking for a stone and having a hard time finding it, we are happy to help. Happy selling.

Sell With a Story: Tanzanite

Everyone has a favorite gemstone, whether it’s classic blue, cheeky pink, sunny yellow, or icy white. Sell With a Story is here to help expand those horizons and turn even the most timid gemstone purveyor into a strong-selling, gemstone enthusiast.

This time, I’m going to discuss the mineral zoisite and the variety known in the trade as Tanzanite. Tanzanite, discovered in 1967, has become an all-around favorite. Collectors and passers-by alike fall for the sparkling colors and range of tones.

Sell With a Story Tanzanite 2020

There are a few things that set Tanzanite apart from the saturated “classic blue” crowd.

The beautiful violet cast you get with a rich, bold blue is my favorite. That violet hue can be seen across stones of all sizes and shapes, and it gives them a springtime pop.

The richness of the stone directly determines the value. The deeper and darker the color, the rarer and more valuable the stone. The lighter-colored, lavender-hued Tanzanite is plentiful making them more affordable. Blues, no matter the specific hue, are generally heated to remove the brown impurities in the color. Blues that are natural with no heat are extraordinarily rare, increasing the value even further.

And did you know that the traditional Tanzanite has gorgeous, less well-known cousins? Let me introduce you to green Tanzanite and bi-color Tanzanite.


Green Tanzanite (sometimes called green zoisite) is a natural, unheated version of zoisite with an earthy-green color. When turned just right, green Tanzanite will show the illuminating violet cast that Tanzanite is known for. The greens are even rarer, which you would think would make them more expensive. However, since this beauty is still relatively unmarketed, you can get larger stones with amazing color for a reasonable price.

Tanzanite ranges on the Mohs scale of hardness from a 6 to 7, and green tends to skew to the top of that range.


In the day and age of wanting something unique and entirely personal, bi-color stones fill a void. Bi-color Tanzanite is no exception.

Displaying a captivating show of greens, teals, blues, and violets, bi-color Tanzanite is comparable to a proud peacock strutting its stuff: even if you don’t like the birds, its hard to look away when they start their show. As natural unheated stones that show a range of possibilities, bi-color stones each have a life all their own. Getting a perfectly matched pair is highly unusual and makes embracing the mismatched trend all the more compelling.

If your customer is not fully captivated by the curious colors of Tanzanite, telling them the story will surely win them over.

Named and marketed by Tiffany & Co. just one year after being found in Tanzania, this stone comes from one place on the planet. This small deposit of very old stones, 585 million years to be exact, are mined in an area just 4 square kilometers wide (approximately 1.5 square miles) neighboring Mount Kilimanjaro.

Tanzanite can fill many needs: 

  • As a less expensive version of classic blue,
  • As an unexpected and entirely unique bicolor and
  • As the lively springtime glow that December babies dream about

The captivating beauty, no matter the shade, has helped solidify Tanzanite as “The Stone of the 20th Century.”

Sell With a Story: Speckled Quartz

I am so excited to introduce you to one of my favorite new stones: speckled quartz. I first saw this curious and unique material when I was at the Intergem show in Idar-Oberstein, Germany. Idar’s rich gem mining and cutting history continue with the addition of this otherwise overlooked variety of quartz.

Found in the iconic and lush rolling hills of western Germany, a true Earth-to-market story, speckled quartz gemstones come from Idar, are cut and polished in Oberstein, and then arrive here in Lafayette, Louisiana, for you to choose from — and are fully traceable along the way.


Sell with a Story Speckled Quartz Variety

What is Speckled Quartz?

Unlike its other quartz counterparts, speckled quartz is dense and opaque with a distinct and memorable pattern. One of its unusual features is that each pattern is one of a kind.

Some individual gems have a face-mask green body and bright teal patches. Others have black bodies and multi-colored patches, or they have an army-green body color with distinctly outlined patches. But all have a notable matte finish with high-polish shiny spots.

Reminiscent of an imagined dinosaur egg, these stones come with variations on cabochon cuts, some with a keel line across the top for an edgy punk vibe, and some with the traditional smooth domes cabochon lovers know and love. In any shape, the stones are noteworthy, large, and vibrant.

So, how do you sell these dynamic oddballs? You tell the story!


The Story of Speckled QuartzSell with a Story Speckled Quartz Square

Since each gem is unique, showing the customer more than one can help mark the differences that make each one entirely their own.

This is a stone you love, or, you love to hate and having that reaction — whether good or bad — will help guide the conversation of exactly what your customer is looking for.

If they love speckled quartz, highlight the details. It’s easy to wear, highly unusual, and definitely a conversation starter. For customers who want a stone that will photograph easily (social platforms await!), the opacity of this stone makes selfies spirited from every angle.

For everyday wear, speckled quartz is in line with other quartz varieties, coming in at 7 on the Mohs scale of hardness. But it also does one even better, having a toughness factor that is higher than average. The opacity of the stone and the pattern will also help hide the wear and tear seen in transparent gems, like scratches and abrasions.

But if it’s Not Love at First Sight…

If your customer is turned off by the playful pattern or the in-your-face spunky nature of speckled quartz, it’s not a losing situation. You now have a starting point for what is “too far” on their personal uniqueness scale.

Sell With a Story: Tsavorite, Demantoid, and Mint Green Garnet

What do pomegranates have to do with garnets? Garnet’s name comes from the Latin word granatum, meaning “pomegranate.” More specifically, garnet refers to the vibrant red seeds of the pomegranate fruit — but while Rhodolite and Mozambique garnet may be the most widely known shades, garnet actually comes in a rainbow of colors. As it turns out, January’s birthstone is quite versatile, having a shade for each Capricorn and early-bird Aquarian.

This Sell with a Story, we’re focusing on three varieties that will have you and your customers green with envy: tsavorite, demantoid, and mint green garnet.

Tsavorite Garnet

Tsavorite comes in vibrant green hues, with some individual gems even rivaling emerald. For this reason, it is considered an alternate birthstone for May.

tsavorite garnet

Most tsavorite gets its color from vanadium. But a deposit in Kenya’s Kuranze area yields tsavorite with chromium, giving them exceptional color with hints of blue.

Tsavorite has a long, rich history since its 1961 discovery. Visit Sell with a Story: Tsavorite Garnet for the in-depth analysis.



Demantoid Garnet

Demantoid garnet is among the rarest garnet varieties. Renowned for its rich hue, demantoid garnet ranges from lush, vivid green to a striking yellow green that’s reminiscent of peridot.

Mint Green Garnet

Mint grossular garnet is also known as mint garnet and, sometimes, Merelani mint garnet — named for being discovered in Tanzania’s Merelani Hills.

How to Care for Garnet Jewelry

  • Garnet is rated “good” for everyday wear.
  • Avoid exposure to heat and sudden changes in temperature.
