Coquimbite With Chalcanthite
Javier Mine, Ayacucho Department, Peru
Miniature, 4.0 x 4.0 x 4.0 cm
This is one of the larger and most colorful specimens overall, 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! The purple coquimbite is included with internal specks of bright blue chalcanthite crystals. I have not seen this before and even in this find, it is not common. These crystals are among the world's best of species now, for both form and the robust purple color. This crystals are so well-developed, and so fine, some of the best of these look 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.
