Tourmaline from the Ibadan region of Nigeria

No. 589: Curved Triangular Brilliant Cut, 7.88 ct., VVS, 13.8 x 13.8 x 8.7 mm, faceted by R. Drummond, $669.80

Achroite, the name given to colorless tourmaline, is rarely found in nature. Shown above is an expertly crafted tourmaline that is the result of a happy accident. I had finished cutting a nice piece of pink Nigerian tourmaline and wished to lighten its color slightly by heat treatment. Not paying careful attention to the temperature and time, this stone was heated until it lost all color; "voila"; achroite! This stone is of very good clarity and exceptionally fine craftsmanship. The symmetry, polish, facet meets and optical performance are outstanding. If you are a gemmologist, or gem connoisseur, here is a great stone for your collection. Certainly your friends will never be able to identify it by color, or lack thereof. If you just wish an unusual stone for a pendant or pin, this stone would be perfectly suited.
