A relatively new addition to the world of gems, clinohumite was first discovered in 1876 within stones erupted from Mount Vesuvius. Only recently have gem-quality pieces been found in locales including Tajikistan's Pamir Mountains. Clinohumite's coloring typically ranges from white to bright yellow to deep orange to red, but a few brown specimens have been found. Gemstones are sought after by gemstone collectors and rarely exceed 3 carats in size.
