Andesine, a red feldspar gemstone, sometimes with greenish tints and a slight labradorescence, A relatively new gem on the market, appearing in 2003, its exact origins may be from a limited deposit of natural red Andesine from an alluvial source in Congo. Although this is possible, it has yet to be proven. Aside from the possible natural stock from the Congo, the material on the market today is produced by enhancing Labradorite through diffusion treatment with copper. A rich orange red gemstone with flash is the resulting gemstone sure to please.
