Chromian Amesite is a chromium (Cr) bearing variety of Amesite that is colored lavender to purple by the presence of the Chromium. Chromian Amesite is named for its chromium content and its relationship to Amesite. Amesite was named in 1876 by Charles Upham Shepard in honor of James Tyler Ames (1810 - 1883), who was an American inventor and part owner of the Chester Emery Mines in Massachusetts and had a rare and unusual collection of minerals. A find of Chromian Amesite in 2001 at the Saranovskii Mine, Urals Region, Russia produced exceptionally rich and colorful specimens with crystals to 4 mm and intense purple colors. Although Amesite crystals are typically too small to be faceted, the Russian Chromian Amesite can be formed into beautiful druzy-style cabochon gems covered in short, sparkling purple crystals as pictured above.
