Chalcedony on Smoky Quartz “casts” after Laumontite Urals A more than worthwhile Ferberite

When it comes to mineral species

A most unusual Calcite specimen from the Idarado that clashes with the typical “feathery” Manganoan Calcites that we are used to seeing from this mine

Specimen # HYALMEX41619

Chalcedony on Smoky Quartz “casts” after Laumontite Urals A more than worthwhile FerberiteThis locality in the Cripple Creek District (purportedly in an old mine shaft) produced unique epimorphs or "casts" of Smoky Quartz and Chalcedony replacing Laumontite.
