Introducing new imaging technology to view and sell your diamonds and gemstones

We know that sometimes selling loose diamonds and gemstones can be challenging for jewelers. After all, customers aren’t quite as adept at viewing stones through a loupe. The new GemCam™ Imaging System is sure to aid gemstone buyers on the road, master jewelers in their store, hobbyists, and everyone in between.

Stuller is proud to distribute the new and innovative GemCam technology. Use the tool itself in tandem with GemCam’s smartphone app to take high definition, 360-degree photos, and videos for easy viewing.

GemCam Features Include:

  • Lightweight, portable device with durable carrying case
  • Long-lasting rechargeable battery
  • Zoom capability up to 40x – similar to microscope quality for clear inclusion identification
  • Built-in LED white lights: up lights and overhead
  • Built-in image cropping tools
  • Gem gripping from 2mm – 16mm
  • * Smartphone/tablet is not included

Tool Applications:

View Stones in Person with Customers – Not everyone can use a loupe as well as a master jeweler. Use the GemCam to view stones alongside your customers, allowing customers to become the expert by empowering them to choose their perfect stone.

Showcase the Stone Online – Use the closeup gem images to share on your social media, website, and email to customers in order to showcase your inventory and boost business.

Diamond/Gemstone Dealer – This portable tool works great on the road, too. Take it with you on gemstone buying excursions to thoroughly examine prospective stones.
