Moss Agate Tumbled Cube

Among the books, decks, and stones on 14th Street is this tumbled stone: Moss Agate Tumbled Cube (shop SKU WJMA6).

Moss agate is a chalcedony with green, moss-like inclusions, usually of chlorite or other minerals, rather than a true moss. In crystal traditions, moss agate is associated with nature, growth, and a steady, grounded feeling. Those ideas belong to folklore and personal practice, not to any medical claim.

Tumbled stones are polished in a drum, which softens sharp edges and brings out color. 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.
