Everyone seems to love watermelon tourmaline,(a crystal with a pink core that runs down the long axis of Elbaite tourmaline that is coated with a green rind.), but it is rare that this distribution of color is useful to the faceter. I have cut emerald cuts with their crowns of the core color and the pavilions of the rind color or visa verse, but the posted gem is the only one I was able to center the core down the long axis of the gem and have balanced bands of rind on both sides. The stone is dichroic and this shows up in the darker pink dominated ends of the long ratio emerald cuts. The core of the stone is eye clean, but the rind, like it is many times, has residual radial flaws.
The posted stone, on its own and not just a unique example of cutting a watermelon tourmaline, is attractive. If it is looked at under the bright indirect lighting of a fading day, it soaks in color like all pastels do and become quite a sight. It weighs 3.75 carats.
