This traditional emerald cut weighs. 5.22 carats. I love this color in tourmaline and it reminds me of warm tropical seas. It is not really dichroic like sea foam. It is bright, open ended and flawless. I came in a lot of selected rough from Namibia. A great deal of Namibian blue to blue/green tourmaline is heated to lighten it even in its rough form, so I don't know for sure, if this piece has been heated or not. Still I purchased this rough from someone very close to the source and it was not presented as heated. Heating tourmaline to lighten indicolite/blue green tourmaline is permanent and is accepted by the trade without a price discount, in part because the labs can not distinguish between heated and unheated tourmaline.
