Item Description
A classic association specimen from the famous Keystone Quarry featuing small whitish crystallized Prehnite with acicular Byssolite and Adularia. The piece comes from the Rich Kosnar collection, and the label on the bottom of the box states that the piece was mounted by D. L. Oswald over 40 years ago. To top it off the piece mentions the name of the famous U.S. mineralogist Arthur Montgomery, although it does not indicate if the piece came from him directly.
