Chalcedony

Chalcedony

A gentle family of stones, soft-spoken and grounding.

Chalcedony (Quartz family)Zimbabwe, Turkey & BrazilTreatment: Varies by variety

Chalcedony is a family, not a single stone. The term refers to microcrystalline or cryptocrystalline quartz that includes agate, carnelian, onyx, sard, chrysoprase, bloodstone, jasper, and heliotrope. It also names the gentle pale-blue or pink translucent stones from Turkey, Madagascar, and the American West. Most varieties share a hardness of 6.5 to 7 on the Mohs scale, making chalcedony durable for everyday wear. Treatment practices vary significantly across the family, and that variation is worth understanding before you buy.
