Bowenite Chrome 28,40 ct (GEM-BC1802)


Beatiful bowenite in cabochon from B. Chatenet's ex-collection. This variety of antigorite is a recent discovery (2011) still rarely offered on the world market. This gemstone presents a rare optical effect called "Usambara", sometimes seen on some chrome tourmalines from Tanzania. The color perceived under ambient light is dark green but at a certain distance and thickness of a strong transmitted light (optical fiber), the color is red.
