143.33 ct Colour Change Garnet

ON CONSIGNMENT

Described as ‘one of nature’s true treasures’, this 143.33-carat colour change garnet from Tanzania is exceptional in both size and quality. Hewn from the 250-carat rough – the largest in the mine’s history – the cushion-shaped, brilliant-step cut exhibits a distinct change from brownish green, in daylight, to rich red, under incandescent light. Untreated and transparent, a top quality garnet like this – displaying both Usambara and Alexandrite effects – is extremely rare. Eye-clean, this garnet exhibits only one discreet feather and, under the microscope, an exquisitely formed fingerprint pattern. Possessing extraordinary characteristics – the kind more usually found showcased in museums – a gemstone of such beauty and scarcity is truly a wonder to behold. Shipping and secure viewing is available on request.
