5.07ct Oval Faceted Sapphire Certified Unheated 11x8mm diamonds Item Size: 14This unheated sapphire is accompanied by a certificate from AnchorCert Gem Lab. Sapphire is a variety of the mineral corundum, an aluminium oxide. It is typically blue but fancy coloured sapphires also occur in orange, yellow, green, brown, purple, pink, black and colourless. Red and reddish pink coloured corundum is referred to as ruby. The variety in colours is due to trace amounts of elements such as iron, titanium, chromium, copper and magnesium.
