Aquamarine Gem

Among the books, decks, and stones on 14th Street is this crystal: Aquamarine Gem (shop SKU AQM98).

Aquamarine is the blue to blue-green variety of beryl. In crystal traditions, it is associated with calm communication and with the sea. 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.
