Description

You are bidding on a small sample that I traded to Dan in 2001, shortly after I found this new species. At the time it was known as triclinic roscherite. There is a single crystal of this rare species on matrix with white prisms of altered milarite and minor fairfieldite. Comes with three 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.
