What is Spinel?

Spinel is a magnesium aluminium oxide that forms sharp octahedral crystals in marble. For centuries red spinel was confused with ruby: the famous "Black Prince's Ruby" in Britain's Imperial State Crown is actually a large red spinel, as is the Timur Ruby. Historic "balas rubies" came from the Badakhshan region, in today's Tajikistan and Afghanistan.

Spinel is rarely treated, and was added as a birthstone for August in 2016.
