Ouro Preto in Minas Gerais is the classic historical source of true imperial topaz, and natural stones of this size with this colour are increasingly scarce. At over 22 mm long, this is a statement stone for a collector or a bold piece of jewellery.

It comes with GRS report GRS2026-062567, which identifies it as a natural imperial topaz and records no indication of thermal treatment. The report is included in the price.
