Accompanied by Gübelin report no. 11060194, dated 29 June 2011, and SSEF report no. 45948, dated 20 February 2006, both stating that the ruby is of Burmese origin, with no indications of heating. The SSEF report together with a letter stating:

"The Graff Ruby

...The described gemstones exhibits an impressive weight and purity, combined with a very pleasant shape and cutting style. The faint inclusions found by microscopic inspection represent the hallmarks of the reputed deposit of Mogok in Burma (Myanmar). The stone has been spared to exposure of thermal treatment and its clarity and colour are natural. Its vivid red, poetically referred to as 'pigeon blood' is due to a combination of well balanced trace elements in the stone, typical and characteristic for rubies of the Mogok gemstone tract.

Natural Mogok rubies from this size, colour and clarity represent a great rarity and the Graff ruby with its combination of outstanding characteristics is a very exceptional gemstone."

Catalogue Note

This spectacular gemstone was first sold at auction nearly nine years ago. It quickly soared to some six times its low estimate and was purchased by the celebrated jeweller Laurence Graff establishing a world record price at auction for a ruby of its size.

Mr Graff named the stone after the sale the ‘Graff Ruby’, and in a Bloomberg interview in February 2006 was quoted as saying ‘…the cut and spread of colour is the finest I have ever seen’.

Since then, the prices for truly exceptional Mogok rubies, arguably the rarest of all gemstones, have continued to soar on the very few occasions they have appeared on the market.
