These are some of the best Augelite crystals to reach the mineral market in a long time. This piece features dozens of fine, sharp, lustrous, colorless, gemmy crystals of Augelite measuring up to 0.5 cm 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. This rare phosphate mineral is not seen often in any format from any locality.
