Additional Info

Spinel is a rare gemstone that occurs in practically all colors. Because of similar properties red and blue Spinels have often been mistaken for Rubies and Sapphires. For example, the Black Prince's Ruby is actually a Spinel.

Where to buy?
For Spinel check what Amazon has to offer. You'll usually find quite a selection from many different vendors. Worth a check. For other high quality gemstones (Rubies, Saphhires, Emeralds) and especially Diamonds, I highly recommend JamesAllen.
