O que exatamente é Granito Preto Shanxi, e de onde vem?

Shanxi preto (Shanxi preto) é um granito preto premium extraído principalmente no condado de Hunyuan, Província de Shanxi, in northern China. Geologicamente, it is actually a diabase (ou diabásio-gabro), an igneous rock composed mainly of plagioclase feldspar and pyroxene with a fine-grained crystalline structure. The quarry area is part of a geological formation stretching roughly 1,000 kilometers from Fengzhen in Inner Mongolia through the Datong mountains down to Fuping in Hebei Province. It is also known by other names such as Imperial Black, Tai Bai Qing (Taibaiqing), Beiyue Black, ou Night Rose no Japão.
