Gemstone of the Week: Clinohumite

(Clinohumite image found on GemSelect.com)

Clinohumite is a stunningly gorgeous and very rare gemstone!  It was discovered in 1876 by Sir Abraham Hume.  This gem (like many others) was first discovered at Mount Vesuvius.  Clinohumite may be various shades of orange, yellow, and brown and is sometimes such an intense orange that it borders on being red.  At present, there are only three known locations where Clinohumite (of gem-quality) may be found:  the Pamir Mountains in Tajikistan, the Mahenge plateau of Tanzania, and in Siberia (the Taymyr region). Clinohumite is about a hardness 6. Ordinarily, this hardness would make it perfectly suitable for use in jewelry, but it still tends to be a fragile stone so great care must be taken when setting it. Because of its rarity, Clinohumite can be very expensive.
