Calcite on Siderite (ex Rich Kosnar Collection)

Item Description

This locality is a bit obscure, but is known to Colorado collectors as it has produced some of the most interesting and easily identifiable Calcites from anywhere. In the early 1980s, Richard Kosnar collected several superb specimens from this locality, which he referred to as "Windy Ridge", but the correct name for the locality is Billy Creek. The piece hosts a sharp, translucent, well-formed, classic, white scalenohedron with a satiny interior. The crystal is associated with minor pink-orange Dolomite and brown Siderite. A very attractive and hard to find thumbnail specimen that would make a great addition to a Calcite suite or a collection of Colorado minerals.
