   Cinnabar  (HgS)
Cinnabar, always quoted by collectors as the No.1 China specific minerals is because Tongren
County of Guizhou Province is the only place worldwide to produce Cinnabar crystals over 1 cm.

The twining of Cinnabar is very distinctive and forms a penetration Spear-like twin that is ridged
with six ridges surrounding the point of pyramid.

Two suggestions to remind Cinnabar collectors

1. Check specimen carefully before buying. Take care not to buy a glued specimen!
2. Always Keep Cinnabar specimen away from strong sun light and heat. Light and heat would
accelerate the oxidation process of Cinnabar and make the crystal dull and less transparent.
