Blue Chalcedony Sugarloaf Cabochon

Featuring an intriguing style, this untreated chalcedony cabochon sports a square shape with rounded, pyramid-like sides. The concave edges of this gemstone form cleaner facets and provide a heavier look to the gem. This cabochon has a silky, translucent blue color and its durability makes it ideal for setting in bezel mountings in nearly any style of jewelry. Use the gemstone individually, in a pair to make earrings or match it with gems of similar or complementary colors for complex designs. A compact microcrystalline quartz, chalcedony (pronounced "cal-SID-nee") is a tough, durable gemstone that is ideal for carving, cabochons and beads. Pure chalcedony is white; individual chalcedonies are labeled by the colors that come from trace minerals. Most varieties of chalcedony are dyed to enhance their color.
