Blue Chalcedony is a demure crystal, subtle and mystic, cool and serene, ethereal yet solid. It has an inviting, soft blue translucence, and an almost imperceptible movement within the stone that invokes a stillness of silent reverence. It's calming, and speaks of spirit and trust.
Chalcedony was considered a sacred stone by the Native American Indians, using it to promote stability during their ceremonial activities.
