Cinnabar carvings from China appear regularly on the market but aren't abundant. Be advised that people have used this material to make a red pigment since antiquity. Some so-called "cinnabar carvings" you may find are actually wood pieces painted with cinnabar lacquer.
Chicken blood stone's red color is due to the presence of cinnabar. Jadeite may also contain traces of this mineral.
Although commonly associated with the color red, specimens may range from brown to gray and even black.
Sources
Hunan Province, China yields the world's finest crystals. Crystalline cinnabar is very rare.
Other notable sources include:
United States: Arkansas, California, Nevada, Texas, Utah.
Bosnia and Herzegovina; Germany; Italy; Mexico; Peru; Russia; Serbia; Spain.
Stone Sizes
Cut specimens are extremely small, normally less than 3 carats. Some rough exists that might cut up to 50 carats. Fine transparent Chinese crystals are unlikely to be cut, since they're extremely valuable as mineral specimens.
Gem cutters can make cabochons up to several inches in size from massive cinnabar.
Devonian Group (Calgary, Alberta, Canada): 2.68 (red, Mexico).
Since cinnabars have a hardness of 2, store any jewelry separately from other stones to avoid contact scratches. Clean only with a soft brush, mild detergent, and warm water. Consult our gemstone jewelry cleaning guide for more recommendations.
