Skeletal Amethyst Backbone Point

Among the books, decks, and stones on 14th Street is this crystal point: Skeletal Amethyst Backbone Point (shop SKU SAS65).

Amethyst is the purple variety of quartz, colored by traces of iron. In crystal traditions, amethyst is associated with calm and intuition. 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 or grade is listed.
