- Aris Phonolite, Namibia
A single, loose, gem crystal of this rare species, from the newest and most significant find for the material in a long time. In fact, it is so unusual for the crystalline form, and the color, that I did not believe the ID was legit till proven 2 years back. This is a very fine single, small but of high quality and obvious gemminess!
