Find anything, fast
Advanced search by stone, shape, cut, origin and certification across natural & lab-grown diamonds, gems, jewelry and watches.
Sell what you don't stock
List virtual inventory and source on demand the moment a customer commits — no capital tied up on the shelf.
Want-list matching
Post what your customer needs and let verified sellers come to you with the match.
Keep your full margin
No commissions, no transaction fees. Every dollar of the sale stays with you.
Vetted suppliers only
Every buyer and seller is a verified business — so you always deal with the real trade.
Anywhere, anytime
Source from the showroom or the road on web and the Polygon mobile app.
One network for the whole store.
Unlike diamond-only platforms, Polygon spans every category your cases hold — so you source diamonds, gemstones, finished jewelry and watches in one trusted place.
Every category, one login
Diamonds, gemstones, jewelry, watches, pearls and more — not just loose stones.
Lower carrying costs
Stock less, source more — free up cash and cut markdown risk.
42 years of trust
The network independent jewelers have relied on since 1984.
Because I can get anything I want by FedEx the next morning via Polygon, I’ve been able to drop my inventory appreciably. And my sales haven’t dropped one penny.
