Turquoise Crystal with Display Card

Among the books, decks, and stones on 14th Street is this crystal: Turquoise Crystal with Display Card (shop SKU KTTA13).

Turquoise is a blue-green copper aluminum phosphate, long prized in jewelry traditions around the world. In crystal traditions, it is associated with protection and communication. Those ideas belong to folklore and personal practice, not to any medical claim.

It comes with a display card. 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.

• SKU: KTTA13
