Fluorite on Orthoclase, Papachacra, Argentina

Dark purple fluorite octahedra tightly stacked on prismatic orthoclase crystals. The grouping and colour contrast make this a handsome miniature. The fluorite is translucent with an interesting "patchy" colour-zoning I have not seen before. Ex Mike Menzies #1116. From the isolated Papachacra area, Argentina. Dimensions: 4 x 5.5 cm
