More Information:

Cinnabar is a brittle, bright red mineral composed of the chemical HgS (Mercury Sulfide). It was mined for its pigment and as a source of mercury by the Romans and has been used by the Chinese and people in different parts of South America for artwork.

Although Cinnabar is a soft mineral, measuring ~ 2.5 on Mohs scale, it is extremely dense and has a higher refractive index (RI) then any other mineral, even diamonds, making it desirable to gemologists.
