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.
