Additional Info

Tourmaline has been a very popular gemstone since antiquity. It comes in a wide variety of colors, many times with two, or even three colors at once. It got its name from the Sinhalese word "turamali", which means "stone of mixed colors".

Where to buy?
For Tourmaline 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.
