Amethyst "cactus" point, February birthstone
A nicely defined amethyst point which has masses of tiny points all over its sides, making it look prickly, hence its colloquial name of cactus amethyst. Discreetly attached to a polished black onyx base. Amethyst is a February birthstone.
3/4 inch (1.9 cm) wide, 5/8 inch (1.6 cm) deep and 13/16 inch (2.0 cm) tall.
