Properties clinohumite belongs to humite group of minerals which is known for having a mixture of silicate and oxide in their structures. It is an extremely rare mineral and an especially rare gemstone. Clinohumite a relatively new addition to the world of gems clinohumite was first discovered in 1876 within stones erupted from mount vesuvius.
Clinohumite is a gemstone quality magnesium silicate with a chemical formula distinguished by silicate and oxide layers. Indeed the mineral is essentially a hydrated olivine and occurs in altered ultramafic rocks and carbonatites. Clinohumite was first discovered in metamorphosed limestone ejected from mt vesuvius in 1876.
