There are about 18 nice purple cubes of fluorite on this gossan matrix from the Ojuela mine. I have been to the mine several times and I've seen a LOT of Ojuela material. Surprisingly, fluorite crystals are not that common from the mine. This piece measures 6.89 x 5.8 x 2.5 cm. The largest fluorite is about half a centimeter on edge. This is not a recent find, it is an older specimen.
