Aura Quartz

Among the books, decks, and stones on 14th Street is this crystal: Aura Quartz (shop SKU WJYAQT27).

Aura, or aura-coated, quartz is natural quartz with a thin metal-vapor coating that creates an iridescent surface. The coating is decorative; any meaning people give it belongs to personal practice.

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.

Namaste Bookshop is on the south side of 14th Street, just west of Fifth Avenue, about a short walk from Union Square.
