Diamonds that finally sparkle on your product pages
Photos flatten jewelry, and standard 3D viewers render gemstones black or milky. GemViewer ray-traces light through every facet so your jewelry looks the way it does in your showroom.

Real ray-traced sparkle
Light is traced through the actual facet geometry of every stone in real time — genuine fire and brilliance, not a flat preview.
Your CAD files work as-is
Drop the .glb you already export from Rhino, Matrix or 3Design. GemViewer accepts files other 3D tools reject.
Automatic stone presets
Diamond, sapphire, ruby and emerald rendered with true-to-life color. Stones are detected in your model automatically.
Fast and mobile-first
Lazy loading, battery-aware frame rates and a photo fallback keep your product pages fast and your Core Web Vitals green.
Simple pricing
Free — 1 product with a 3D model, all rendering features included.
Unlimited — $49/month — unlimited products, priority support.
