About ClinohumitesClinohumite is a gemstone variety belonging to the Humite group of Minerals. It is quite uncommon and sought after by collectors due to its extreme rarity. There can be said to be only a few thousand carats known to exist, almost all of which are in private collections.
It is typically dark brown to orange in color somewhat similar in appearance to hessonite garnets. They have an orange-yellow fluorescence under short wave ultraviolet light. Their refractive index ranges from 1.623 to 1.728 and they have a hardness of 6 on the Moh's scale.
Clinohumite was first discovered in metamorphosed limestone ejected from Mt Vesuvius in 1876 however the occurrence was too small and commercial to be converted to gemstones. Transparent gem-quality bright yellow to deep orange clinohumite was found only recently (in the early 1980s, and later in 2000) in the Pamir Mountains of Tajikistan. There are a few other notable deposits such as Taymyr region in Siberia which had occurrence which was dark brown in color and the more recent find in the Mahenge Plateau in the Ulanga District of the Morogoro Region of Tanzania, Africa in 2005.
