Sell or consign Diamonds

Loose GIA-certified diamonds and diamond rings of every shape, from one carat to important stones.

Send us clear photos, any certificates or receipts, and what you know about the history of the piece. We provide a valuation, then offer it through our gallery or to major auction houses — Sotheby's, Christie's, Phillips, Bonhams and others — choosing the venue that should achieve the strongest result.
