Blue Chalcedony Round Rose-Cut Cabochon

This round chalcedony cabochon features a silky, translucent blue color and its durability makes it ideal for setting in bezel mountings in nearly any style of jewelry. The stylish rose cut emphasizes the pastel blue color. Combine it with complementary-color gemstones to create mixed-gem 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 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. A favorite of yesteryear, this rose-cut faceting features a flat base (no pavilion) and a crown made up of triangular facets.
