Chalcedony on Smoky Quartz “casts” after Laumontite Urals "sword"-shaped crystals of Vivianite with

"sword"-shaped crystals of Vivianite with white bladed Barite and minor metamorphosed Sandstone

You will have a very hard time finding individual crystals of Wavellite this size from any locality

A more than worthwhile Ferberite that would make a great addition to any collection

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

Most everything that evades the crusher is usually taken out of Bolivia by a geologist who has an "in" at the mine

Chalcedony on Smoky Quartz “casts” after Laumontite Urals "sword"-shaped crystals of Vivianite withThis locality in the Cripple Creek District (purportedly in an old mine shaft) produced unique epimorphs or "casts" of Smoky Quartz and Chalcedony replacing Laumontite. The Smoky Quartz has a distinctive muted silvery grey color, with very little luster and a somewhat stalactite esque growth due to the way the Quartz overgrew the preexisting Laumontite. The lack of luster on the Quartz is most likely due to a micro coating of Chalcedony. The biggest
