The 10 New Diamond Offerings of This Year

Stuller's monthlong celebration of Diamond Days of December continues.

It’s inevitable that the end of a calendar year brings about a time of reflection. As I look back on 2021, with all its highs and lows, I can’t help but be incredibly thankful for the position I find myself in — surrounded by the most amazing, hardworking teams and, of course, all the beautiful, shining diamonds we’re able to offer our customers. And speaking of our customers —you are the ones we should be most thankful for! Because of you we’ve been able to expand our diamond offerings all year long. We hear you, with all of your wonderful suggestions, and hope that 2021’s new diamonds have fulfilled at least some of your wishes.  

As Stuller’s monthlong celebration of Diamond Days of December continues, we take a look back at the 10 new diamond offerings we’ve added in 2021. A mix of classic, unique, and on-demand diamonds sure to make anyone’s day – or year – just a little brighter!
