Chalcedony is one of the Quartzes. Perhaps the most prized is Blue Chalcedony. It can range from a regular blue to a grayish blue. Chrysoprase is the apple green Chalcedony. Chalcedony was a sacred crystal to some American Indian tribes, helping the community ties to remain strong and it encouraged visions. Chalcedony balances the physical, emotional, intellectual, and ethereal (spiritual) bodies.
