The November 12th, 2014 Sotheby's Geneva auction was lead by a truly magnificent pigeon-blood colored ruby known as the "Graff Ruby".  The ring was originally sold at auction nine years ago and was purchased by noted jeweller Laurence Graff for a record breaking price. He later named the ruby "The Graff Ruby". 
In Geneva the ring again fetched a record breaking amount (selling for $8,600,410). The ring was part of the Collection of Dimitri Mavrommatis (16 pieces) which also included a rare 27.54 carat step-cut Kashmir sapphire, as well as several pieces by contemporary jewelers, Graff and JAR (who was represented by a pair of superb sapphire, ruby and diamond earrings).

The "Graff" Ruby information:
The piece was accompanied by Gübelin report 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."
