About Clinohumite
Clinohumite is an uncommon, brittle, magnesium silicate mineral that somewhat resembles the hessonite variety of grossular garnet. Specimens can be orange, yellow, red, brown, or a combination of those mentioned. It was first discovered in 1876 in metamorphosed limestone from Mount Vesuvius, and gem-quality crystals were first found in the Pamir Mountains of Tajikistan in the early 1980's. Clinohumite crystals are typically smaller grains, with larger crystals being highly sought after by mineral collectors.
General Chemical Formula - (Mg,Fe)9(SiO4)4(F,OH)2
