Cinnabar

saf-ahyuh r

Named from Arabic and Persian words for "dragon's blood," cinnabar comes in a remarkable brick-red color and has been used as a pigment in China as far back as prehistoric times. Gem crystals are rare collector's pieces, but opaque material is often cut into cabochons. Natural cinnabar is a major mercury ore and not used in jewelry making, but a resin product that closely resembles it is used in jewelry and called cinnabar. The red color is so fresh and vibrant that, in China, many call it "China Red."
