Built by the trade, for the trade.
Polygon began in 1984 — before the internet — as a way for jewelry professionals to find each other and trade with trust. Four decades later, that mission hasn’t changed. We’ve simply built the most complete, secure and easy-to-use marketplace to make it happen.
Today, thousands of vetted businesses use Polygon to source and sell diamonds, gemstones, jewelry, watches, pearls and more — across one trade-only network on web and mobile. There are no commissions and no transaction fees, because we believe the value you create should stay with you.
What we believe
The jewelry trade runs on relationships and trust. Our job is to protect both: every member is vetted, every deal is on the record, and every tool is built to help independent businesses compete and grow. We’re investing heavily in the member experience so the people who power this industry have a platform worthy of it.
