A beautiful pair of oval shape cabochons of natural blue chalcedony hand polished with the weight of 91.45 cts and dimension of it is 22×30×9 mm. 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 the form of Quartz that is compact and microcrystalline. It occurs in many different forms, colors, and patterns, and many varieties have been used as gemstones since antiquity. In the gemstone trade, the term Chalcedony is often used specifically to describe the white, gray, or blue translucent type of Chalcedony, but its technical term includes all additional varieties.
