...he Star of India is also unusual because it has stars on both sides of the stone.
One of the oldest known sapphires is the 104 carat Stuart Sapphire which dates back to 1214. It was once mounted in Queen Victoria's State Crown and is now set on the back side of the British Imperial State Crown.
Among cut sapphires, the largest in the world is known as Queen Marie of Romania's Sapphire ( pictured ), at 478 carats. It combines stunning color with a fascinating history. According to lab reports, it is of Sri Lankan origin and is completely untreated. It was purchased by King Ferdinand of Romania in 1921 for his wife Queen Marie, who was a granddaughter of both Queen Victoria of England and Czar Alexander II of Russia. The sapphire was sold around 1947 and was acquired by Harry Winston. The stone is now on permanent display in the Diamond Fund Exhibition, within the Kremlin Armoury Museum in Moscow.
