These are some of the best Augelite crystals to hit the mineral market in a long time. This piece features a fine, sharp, lustrous, colorless, gemmy crystal of Augelite measuring up to 2.2 cm sitting atop micro Siderite crystals on matrix. The quality of the Augelite crystal is very good and it is one of the largest crystals I've seen from this mine. The crystal on this specimen is 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!! 5.1 x 4.2 x 2.8cm
