Natural Bi-Color Purple Tourmaline 2.12ct Polished Tumble

Not a faceted stone but a polished freeform, worked into a soft wedge with one rounded tip and a broader squared end. The color is the interesting part: a bright magenta-pink concentrated at the narrow tip runs back into a soft greyish lavender-violet across the body, with a darker plum band drifting through the middle. The finish is a high gloss all over, and a little natural pitting remains at the wide end. The material is semi-transparent, so light enters the surface and glows from within.

Polishing suits tourmaline like this, where the color zoning and the semi-transparent body show best across a smooth curve. It is untreated African material. Tourmaline is 7 to 7.5 on the Mohs scale, and a freeform piece like this suits a wire wrap, a bezel that follows its outline, or simply a place in a collection of color-zoned tourmaline. Tourmaline is the modern October birthstone.
