Surely one of the most exotic of faceted species - Sulfohalite is almost unheard of in faceted examples. This is not least because the hardness of this mineral is 3 1/2 on the Moh's scale, so faceting is difficult to say the least. This wonderful US gem curiosity is from the famed evaporite mineral deposits in California's San Bernadino Co. and is one of only two such examples we have ever had. The color is a typical very light brownish-yellow and the stone is quite respectably transparent for the material - what is particularly intriguing is the internal series of growth structures that result in an iridescent flash across the entire table. This adds quite a bit of color and visual interest to the stone. Most unusual.
