Phosgenite is a lead mineral that is exceptionally rare as a gem material - it has a hardness of only 3 on the Moh's scale and is extraordinarily difficult to cut.  In fact, it is not necessarily that gem rough that is completely unobtainable, it is finding someone willing to cut it.  Phosgenite is nearly impossible to polish and flat out loves to splinter away to nothing.  Despite this, the high refractive index and adamantine luster (due in part to the lead) make the prospect of gem Phosgenite somewhat irresistible to collectors.  To say we were rather taken aback by the quality of this gem is something of an understatement; this is without a doubt, the very finest cutting we have ever seen achieved on this material.  You may indeed recognize the cutting as the work of a regular contributor to goods on this site, an amazing talent to be sure.  The size is simply magnificent and the color is extremely attractive.  Moreover, the locale is a classic and rough from here is simply unavailable.  A statement rarity if ever there was one!
