Semi Precious Stone Clinohumite

Clinohumite is the other member of humite group of mineral composing a magnesium silicate with a chemical formula (Mg,Fe)9(SiO4)4(F,OH)2. The common colors of clinohumite are fashioned into bright, yellow orange gemstones. The two sources of gem quality material are the Pamir Mountains of Tajikistan, the Tyamyr region of northern Siberia. It is one of two humite group minerals that have been cut into gems, the other being the much more common chondrodite.

The monoclinic mineral clinohumite is typically dark to light brownish, orangey yellow and resemble the variety of grossular. The specific gravity for the mineral is 3.2 to 3.4 and the Mohs hardness is 6. The luster ranges for dull vitreous to resinous and the refractive index is 1.631, 1.638 – 1.668 and 1.668.
