A cluster of naturally coloured purple amethyst crystals from Brazil. This is actually the end of a stalactite or stalagmite. Do you know how to tell which is which in situ? A stalactite has to hold on tight, a stalagmite might reach the roof. Amethyst is a February birthstone.
1 3/16 inches (3.0 cm) wide, 1 inch (2.5 cm) deep and 7/16 inch (1.1 cm) tall.
