Spinel is a gemstone that has been confused with ruby and sapphire for hundreds of years. Several of the most spectacular spinels ever discovered have been mounted in "crown jewels"  under the assumption that they were rubies or sapphires. The most famous being the "Black Prince's Ruby" in the British Imperial State Crown. 
 
Spinel occurs in the same colours as rubies and sapphires and is formed under the same geological conditions. They were recognised as a separate gemstone in the mid 1800's.
