This beautiful emerald cut weighs 5.78 carats. It is clean and bright with great transparency for a medium dark toned gemstone.
This is a beautiful gemstone. Its bluer a/b axis blends beautifully with the more yellow green c axis. I said blend because the tone level of both axis are the same and that gives such a light bright feeling to a stone that is at least a medium tone level gem. I wish that all the African greens would learn from the best Afghanistan greens on how to really behave. I would not call this the highly prized “sea foam” tourmaline because it is too rich, but the same desirable qualities are present, with the possible exception of not being a “neon” gem. Top quality sea foam Afghanistan tourmaline has a “neon” brightness that I have only seen in one other type of tourmaline. That is a high quality paraiba type tourmaline. The effect can not be photographed and makes “neon” gems appear to generate more light than they are receiving, under lower light conditions. Incandescent lighting really helps in this case as is usual with blue and green tourmaline.
This well proportioned emerald cut is clean and bright, with a weight of 5.78 precious carats.
