Dragon Jade Qing Dian 20mm Mushroom Shaped Crystal

Among the books, decks, and stones on 14th Street is this mushroom-shaped crystal carving: Dragon Jade Qing Dian 20mm Mushroom Shaped Crystal (shop SKU A222).

Jade in jewelry and carving may be nephrite or jadeite, both tough, fine-grained stones long prized in many cultures. In Chinese and other traditions, jade is associated with harmony, virtue, and protection. Those ideas belong to folklore and personal practice, not to any medical claim.

The title lists a size of 20 mm. 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: A222
