Abstract: Bloodstone is an unique Chinese precious stamp stone，consisting of “blood” (fine-grained cinnabar aggregate) and “ground” (fine-grained dickite aggregate)．Up to now，the bloodstone deposits were discovered only in Changhua of Zhejiang Province and Balin of Inner Mongolia，which are situated in Mesozoic－Cenozoic circum－Pacific active continental margin of China．Comparative studies show that some mercury deposits in Okhotsk－Chukchi volcanic rock belt of northeastern Russia possess many similarities with Chinese bloodstone deposits in many aspects，including regional tectonic setting，volcanic host rocks，ore-controlling structure and ore—body morphological feature，alteration of host rocks，sub-volcanic rocks and genesis of the deposits．Some mercury ores from the mercury deposits may be used as bloodstone gems in the near future．
