Quartz epimorph after Fluorite with Ankerite and Sphalerite

Three-dimensional 'skin' of microcrystalline quartz epimorphing fluorite crystals that have dissolved away.. A little Ankerite has coated the positive epimorph whilst the coverage on the negative epimorph is much richer along with a dusting of sphalerite crystals. Neat and unusual specimen..
