Tasna mine, Rosario section of Cerro Tasna, Nor Chichas Province, Potosi Department, Bolivia - This material was some of the first Augelite to come out of Bolivia in a long time when it hit the market in the early 2000's. This piece features several sharp, highly lustrous, gemmy crystals of Augelite measuring up to 7 mm associated with greenish-brown compressed rhombohedra of Siderite with lustrous octahedral Pyrite on micro Quartz matrix. This is definitely one of the showier specimens of Augelite we've offered from Tasna, in a while as many of them are just lumps. It's a very good quality piece for the species, and the associations make it very desirable for collectors. If you're a Bolivian mineral collector, do not pass this one up, because it's a very worthwhile Augelite from Tasna. Ex Rob Lavinsky collection.

Machacamarca Mine, near Colavi, Dept. Potosi, Bolivia - These are some of the best Augelite crystals to hit the mineral market in a long time. This piece features dozens of fine, sharp, lustrous, colorless, gemmy crystals of Augelite measuring up to 5 mm associated with minor octahedral Pyrite plus Quartz on matrix. The quality of the Augelite crystals is very good and they are certainly good sized for this mine. The crystals on this specimen are definitely some of the best quality I've seen from Bolivia as well. This rare phosphate mineral is not seen often in any format from any locality.
