About Spinel Gemstone
The Spinel Group of minerals includes Spinel, Gahnite, Galaxite, Hercynite, and Magnesiochromite. Although Spinel is most famous for its red variety, it is also found in other colors such as green, blue, purple, brown and black. The blue Spinel is colored by cobalt and is quite beautiful. Star Spinel and color-change Spinel are also (rarely) found.
Spinel is a historically important gem because it has been mistaken for Ruby in some very famous crown jewel collections. Perhaps the most famous of these is the Black Prince’s Ruby set in the British Imperial State Crown (Crown Jewels of England). It is estimated to be 170 karats. Originally thought to be a large Ruby, it was later proven to be a fine Spinel. Although Spinel gems are usually small, 3 karats or less, very large gems have been cut. The largest is probably the 520 karat gem found at the Banque Markazi in Teheran, Iran.
