These are some of the best Augelite crystals to hit the mineral market in a long time. This piece features a two fine, sharp, lustrous, colorless, gemmy crystals of Augelite measuring up to 2.0 cm sitting atop micro Siderite crystals on matrix. The quality of the Augelite crystals is very good and they are some of the largest crystals I've seen from 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!! 6.8 x 4.3 x 2.2cm
