Black Spinel is not well-known in the gem world, yet its outstanding features make it the ideal choice for an opaque black gem. These days, where most gems undergo routine enhancement treatments, Black Spinel can stand proud as a gem requiring nothing more than cutting and polishing to bring out its inner beauty. If you want a totally natural and untreated black gemstone – Black Spinel is the one!
Black Spinel has been often called ‘Black Sapphire’ or ‘Nin’ in Thailand. Miners here often call it Blackjack and regard it as an indicator of good Sapphire being present in the wash. Let there be no confusion though as Black Spinel is an excellent gemstone in its own right.
Black Spinels are rated at 8 on Moh's Scale of Hardness and are a durable stone that lacks cleavage, making it suitable for all jewelry purposes. Black Spinel looks elegant when set with a quality piece of gold or silver jewelry because of the striking contrast. Black Spinels are a favorite amongst gem connoisseurs and gem collectors alike, and makes a beautiful, durable stone for all jewelry purposes.
This mineral gem is magnesium based and formed in metamorphic and plutonic rock formations. This relatively opaque black variety of Spinel known as the Pleonast or Pleonaste is found in very few areas. Traditionally, Thailand (Boi Ploi, Kanchanaburi) is considered to be the finest source.
