Amphibole Quartz Polished Point

Among the books, decks, and stones on 14th Street is this crystal point: Amphibole Quartz Polished Point (shop SKU DAMQ8).

Quartz is crystalline silica, a hard, durable mineral found in many colors and habits. In crystal traditions, quartz is often associated with clarity. 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.

• SKU: DAMQ8
