Your inventory, your suppliers
Gemtheon securely connects to your vendor accounts (Rapaport, Nivoda, Polygon) and your in-house diamond catalog. You control which stones display and what margins apply.
Three leading feed sources
Aggregate your Rapaport, Nivoda, and Polygon accounts into one unified dashboard. Manage pricing, filter rules, and feeds in one central hub.
Zero inventory carrying cost
You never buy the stone until the customer commits. No capital tied up in unsold stock, with full control over customer pricing.
Real-time availability
Every stone shown is available right now.
Gemtheon pulls live availability at page load. If a stone sells anywhere in the network, it disappears from your store. No manual updates. No awkward "sorry, that stone sold" conversations.
- Live availability checked on every page load
- Automatic removal of sold or reserved stones
- Real-time Rapaport and market pricing
- Multi-source fallback if one feed is down

- Cert lab filter — GIA, IGI
