black ruby

Corundum is not always ruby, and other varieties of gem-quality corundum that are not red are known as sapphires. Pure corundum is colourless and it is the slight trace of elements such as chrome, iron, titanium and vanadium that creates the colour. The close relationship between rubies and sapphires has only been understood since the beginning of the nineteenth century. Before then it was believed that red garnets or spinels were also rubies. In fact the ‘Black Ruby’ and the ‘Timur Ruby’ in the British Crown Jewels are spinels rather than actual rubies. The balas ruby is a type of spinel; Bohemian rubies are derived from rose quartz and Siberian rubies are really pink or red tourmalines.

Ruby forms as crystal within metamorphic rock and they have been mined for more than 2000 years. The most prolific ruby mines are in Myanmar (formerly Burma), Thailand, Sri Lanka and Africa and rubies are ranked as among the most valuable of the world’s gemstones. Although a lot of rubies are mined, high quality rubies are actually very rare. This scarcity of good rubies is due to chrome. The chrome is responsible for giving the ruby its gorgeous red colour, but when the ruby was being formed deep in the earth’s crust it was also the chrome that caused the huge amount of cracks and fissures within the crystal. Only a few rubies had the ideal conditions in which they could grow to a large size and stay in perfect condition, and this is why there are so few rubies of more than 3 carats in existence. One consequence of this rarity is that a ruby of large size with few inclusions can sometimes fetch more money at auction than a comparable diamond and the most expensive ruby ever sold at auction in 1988 was 15.97 carat gem that went for $3.63 million.
