Sell or consign Zambian & Rare Origin Gems

Gems with notable origins — Zambian emeralds, Tanzanian tanzanite and more.

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.
