The Orlov diamond is part of the collection of the Diamond Fund of the Moscow Kremlin and can be traced back to the 18th century Sri Ranganathaswamy Hindu temple, in Srirangam, Tamil Nadu, India where it once served as the eye of the presiding deity.
Described as having the shape and proportions of half a hen's egg, the Orlov is a rarity among historic diamonds, for it retains its original Indian rose-style cut. Its color is widely stated as white with a faint bluish-green tinge and is estimated to weigh 189.62 carats.
This diamond should not be confused with the "Black Orlov diamond", called the Eye of Brahma, which according to legend was stolen from a Temple near Pondicherry.
