RUBELLITE TOURMALINE 5.96cts
Members of the tourmaline family of minerals have the same
basic crystal structure, but occur in many colors. Rubellite (from the
Latin for Red) is the name given to the pink or red variety, with ruby
red stones the most highly prized. Rubellite crystals ar striated with
triangular cross section and a rounded outline. They may also occur with
a fibrous habit and show a cat's eye when cut in cabochon form. Russian
pink and red tourmaline occurs in weathered granites. Other sites include
Madagascar, the USA, Brazil, Myanmar and East Africa. The specific gravity
of tourmaline varies with color, dark red has a higher SG than pink. |
