Gemmy, twinned, honey-brown colemanite crystals, with flashes of interior fire, richly and aesthetically cover the mounded matrix on this showy and excellent specimen from the small, one-time 2005 find in Turkey. Very interestingly, a second generation of totally colorless colemanite is found on the edges of the crystals. Ex. Tarnowski Collection.
