I bought this Tourmaline gemstone in Bangkok, Thailand about 15 years ago. It weighs 70 carats and the low end of the price for gemstone Tourmaline is $100 per carat today. Obviously, my price was quite a bit less and it is reflected in the price of this piece of jewelry. The stone is 1 3/4" X 1 1/4". I have hung it on a 16" 14K gold figaro chain.
