2/$20, Small Glass Bottle Pendant w/ Tiny Genuine Blue Chalcedony Cabochons

Small Glass Bottle Pendant w/ Tiny Genuine Blue Chalcedony Cabochons There are 20 tiny genuine high-quality blue chalcedony cabochons in this small bottle. 1 3/4". Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. In common practice, only the translucent, single-color types of this material are sold under the name “chalcedony.” Blue chalcedony is a highly prized gemstone. The blue variety of chalcedony occurs only when it does not contain many color-changing impurities. This stone is perfect for carving, cutting, crafting, and tumbling. The most valuable natural specimens of blue chalcedony bend the light in such a way that they appear to be lit from within.
