These are some of the best Bolivian Augelite crystals to hit the mineral market in a long time. This piece features a fine, sharp, lustrous, colorless, gemmy crystal of Augelite measuring 9 mm sitting atop micro Quartz crystals on matrix. The quality of the Augelite crystal is very good and it is a very good sized crystal from this mine. This rare phosphate mineral is not seen often in any format from any locality. Ex. Brian Kosnar.
