On a matrix formed by well-developed quartz crystals, almost completely covered by rosette-shaped aggregates of muscovite crystals, on which numerous pyrite crystals shine, we can observe various aesthetic prismatic fluorapatite crystals with very good brilliance. Prismatic forms with striated faces truncated by basal pinacoids and small faces of hexagonal dipyramid. With transparence and a very uniform violet color. A very aesthetic specimen.
