Empire Diamond has been a fixture of the New York trade since 1931. In that time we have been a buyer, a consignor, and a reliable counterparty to jewelers, estate attorneys, and dealers across the country. We know the difference a trustworthy partner makes when a piece, or a payment, has to be exactly right.
What we offer the trade
Consignment
Place your pieces with us on agreed terms. We market and sell through our showroom and private channels, you retain ownership until sale, and you are paid promptly on completion. Full transparency on pricing and status, at every stage.
Purchasing
We buy outright: signed pieces, important diamonds, estate jewelry, and quality stones. A trained gemologist evaluates the lot and you receive a firm offer. No consignment wait when you would rather sell direct.
Sourcing
We open our inventory and our network to the trade at professional terms. Decades of relationships, working for you.

How it works
01: Apply
Tell us about your business and what you're looking to consign, sell, or source. Trade access is reviewed and approved individually.
02: Establish terms
We agree on consignment splits, purchasing terms, or sourcing arrangements in writing, before anything changes hands.
03: Transact
Pieces are evaluated, insured, and handled under our policy.
04: Settle
Prompt payment on purchase, or on sale for consigned pieces. Clean records, every time.

Why dealers work with us
A trade relationship is only as good as the counterparty behind it. Empire Diamond has been good for it since 1931, through every market, with a reputation built one fair transaction at a time. Our gemologists are formally trained and our valuations hold up to scrutiny. We pay when we say we will. We are discreet by default, because in this trade discretion is not a courtesy, it is the cost of doing business.
That is the whole offer: expertise you can rely on, terms you can see, and a partner who has been here for nearly a century and intends to be here for the next one.
