Collection: Tourmaline

Tourmaline is a complex borosilicate that crystallizes in a wider range of colors than almost any other gem, from green verdelite to pink rubellite and bicolor combinations. 22sGems sources gem tourmaline from classic pockets including Aricanga and Cruzeiro in Brazil, and Paprok and the Malkhan region in Asia. Collectors look for glassy luster, clean terminations, and the crisp vertical striations that define the species.
