This is an Indicolite, a trade name for blue tourmaline, that you should appreciate. It is a stable bright blue that sparkles all over the small emerald cut. I know it is from Namibia, just by looking at it. It appears to be eye clean and with great transparency. Nothing dark or vaguely green or gray about this beauty. Oh, did I say that I love top grade Indicolite from Namibia. I don’t think there is a better blue in the world. This small emerald cut weighs .70 carats.
