This is one of the sharpest large, individual barrel-shaped crystals in a lot I obtained at Tucson from this small 2009 find. Really quite remarkable for both species AND for a locale from which we never suspected or saw such things before! These crystals are among the world's best of species now, for both form and the robust purple color. This is much better in person! The minute dusting of yellow crystals is copiapite and the small white sprays are alunogen. This crystal is so well-developed, and so fine, it looks more like an Afghani apatite than any coquimbite I have seen from other locales, and many people were saying they are now among best of species material at the show. I am told a limited number came out. From the several hundred specimens we saw, we selected a few dozen of which this, although small overall, is one of my favorites.
