This indicolite has a touch of green, which is much more common than the pure blue to purple side of tourmaline, open ends which is less common and more desirable to me than dark closed ends, and is flawless which everybody likes.  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 material.</ins></div></td></tr>
