Tourmaline in Quartz Tumbled Crystal

Tourmaline in Quartz Tumbled Crystal is a tumbled stone (shop SKU L1095A) on the shelves at Namaste Bookshop in Manhattan.

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.

Tumbled stones are polished in a drum, which softens sharp edges and brings out color. 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.
