Dioptase from Namibia 0.150ct loose Japanese-German book
Dioptase is a gemstone characterized by its vibrant emerald green color with a slight bluish tint. Its color is so similar that it is said to have been mistaken for an emerald when it was first discovered. Due to its fragile nature and the fact that it is often found in small, granular crystals, it is a rare stone that is rarely cut. It comes with a certificate of authenticity from the Japan-German Gemological Institute.
