Fine examples of larger, bi-color Tourmalines in which one of the colors is actually colorless are quite scarce.  This absolutely precision cut example features a roughly 60/40 split between a bright bluish-green side and a perfectly colorless one - a classic Afghan set of colors.  The contrast is lovely - the green side is really set off by the colorless.  Exceptionally well cut, it is possible to get a nearly full return of light here - zero windowing at all.  There are a few extremely thin feathers near the color separation that have been oriented as to be essentially invisible when viewed straight on.  A fine size and very attractive.
