This large round, untreated chalcedony cabochon has a silky, translucent blue color and its durability makes it ideal for setting in bezel mountings in nearly any style of jewelry. Combine it with complementary-color stones to create mixed-stone pendants, rings and bracelets or use it by itself to draw attention to its soft, blue color.

A compact microcrystalline quartz, chalcedony (pronounced "cal-SID-nee") is a tough, durable stone 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.
