Sulphur - large hoppered crystals
El Desierto Mine, San Pablo de Napa, Daniel Campos Province
6.4 x 3.2 x 2.4 CM (cabinet)
Very pure Sulphur in textbook perfect crystals showing aligned prism forms and hoppered faces. Excellent bright yellow color and in undamaged condition, a modern classic. The El Desierto Mine is a rather small operation located on the flanks of a volcano at very high elevation. It has not been worked for a few years and when we visited the locality some time ago it was really inhospitable to say the least. However the best Sulphur specimens in recent decades have come from here. Better pieces like this have vivid canary yellow color, very bright luster and are rather transparent. The color is much brighter than most specimens of the other classic localities (Sicily and Russia) and there is no hint of Petroleum inclusions that are common elsewhere. These large crystals show very clear epitaxial stacking and exceed 5 CM. Choice for the locale and for the specie. Far better than the usual quality from this unusual place.
Very odd, single large etched crystal of Sulphur, complete all around and complexly stepped. Bright color and in perfect condition, this high elevation locality at one time produced a few fantastic world class Sulphur crystals. Sulphur is a common element world wide but there are few good crystal localities. The former mines in Sicily, Russia and Bolivia were the greatest sources and specimens from each are completely different. The legendary Rock Currier was very involved in importing Sulphur specimens from here years ago. When we visited the locality in 2012 it was completely shut down with nobody there. I am not sure if it has worked since. This specimen is from over 25 years ago.
