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 is not used in jewelry making, but a resin product that closely resembles it, is used in jewelry. The red color is so fresh and vibrant that, in China, many people call it "China Red."

History

Cinnabar was used to create the scarlet red pigment vermillion. The earliest use for vermillion comes from a Neolithic burial site in Palencia, Spain that dates to 5,000 years ago. The body was covered in vermillion, and it is believed that the pigment was used to preserve the remains of the deceased. The pre-Columbian civilizations of Mesoamerica (c. 1200–400 BCE) used powered cinnabar to decorate statues found in ancient temples. There is evidence for organized cinnabar mining in Huancavelica, Peru that dates to 1400 BCE. It is believed that the pre-Columbian Andean cultures and the Incas used the mercury ore to refine gold. The powder was used for thousands of years as a rouge and as an ink for writing. In the Neolithic period in China the cinnabar was powdered and mixed with the sap of rhus verniciflua trees to create a natural plastic. The lacquer was applied in multiple layers to vessels and decorative objects and then carved into geometric patterns or scenes from nature. This technique was popular from 600 BCE until 200 AD in China.

Care

Gentle wear, avoid ultrasonics and high heat. Modern resin cinnabar is safe and does not contain mercury.
