Green Tourmaline

Among the books, decks, and stones on 14th Street is this crystal: Green Tourmaline (shop SKU GTFEL259).

Tourmaline is a group of complex silicate minerals that occur in many colors, including pink and black. In crystal traditions, tourmaline is associated with protection and with balancing energy. Those ideas belong to folklore and personal practice, not to any medical claim.

Natural stones vary in color, clarity, and shape, so the piece you receive will have its own character even when the weight, grade, or size is listed.
