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 are striated, with a 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.
