To be a GEM (highest quality gemstone) in the world of green tourmaline is saying a lot. The competition from chrome tourmaline and cuprian tourmaline is intense. Now I am not saying that this gem can match the level of saturation (purity of color) of the best chrome tourmaline or the neon qualities of the best cuprian tourmaline, but in its world of Elbaite (most common species of tourmaline in gemstones) this emerald cut is a GEM. I don’t think that it can get better than this bright, richly toned, highly saturated, non-dichroic green GEM. The GEM appears eye clean and with a fine, complete set of seven row of facets that meet the standards of the collection. I want to reiterate that the GEM is NOT dichroic. This is not really rare in lighter toned gems, but in an Elbaite that is this rich in tone, it is most unusual. It also points out the fact that you CAN NOT us dichroism as a means to determine if a gemstone is a tourmaline or not. Finally if you really want a treat, take this GEM and put it in my secret place next to a twisty florescent light inside a yellowish shade and the green blaze will amaze. This GEM weighs 4.45 precious carats.
