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 is known as the Speaker's Stone, the stone of one who must measure his words. It encourages reflection and meditation, its gentle radiance preparing us for action but helping to hold back words we might regret.
