One-of-One Stones
Every stone in this collection exists exactly once. Each is a natural, earth-mined gemstone — Ceylon and Australian sapphires, rubies, emeralds, opals and rarities — assessed in-house by our FGAA-qualified gemmologist, with treatment disclosed in writing on every listing and recorded in our public Treatment Register. When a one-of-one stone finds its owner, it is gone. Each carries its own Digital Gemstone Passport, and every purchase includes free insured delivery and free lifetime re-authentication by the house.
