Description

You are bidding on a beautiful miniature sample with a matrix of rich, iridescent chalcopyrite hosting many nice groups of tennantite crystals with a few chalcocite plates. Rich sample obtained by Dan from Casey Jones in 1996. Comes with two original slides scanned and shown here. 

This sample is from the collection of Dan Behnke, long-time friend, micromounter and prodigious photographer. I am pleased to be able to offer selections from his large collection, many of which are illustrated specimens in Rocks & Minerals, The Mineralogiocal Record, Photo Atlas of Minerals and many other publications. All samples from his meticulously catalogued collection will come with his original index card with all notes, photography annotations and other pertinent information, as well as any slides Dan may have taken of the sample with publication notes and date the photo was made.
