Emerald cuts have a formal feeling to them and when that is combine with a color that does not want to play, you are dealing with a presence. This open ended blue tourmaline does let a little slide into blue green with my yellow light, but it never looses it cool. I sure that it dress for dinner and prefers attire with a touch of gray like himself. He is a good tourmaline to deal with because he is clean cut and not exceptional bright, but still a good medium toned fellow all around. It weighs 1.20 carats.
