HEAVILY ILLUSTRATED!!! You are bidding on a small, but prominently illustrated sample with beautiful bladed sinkankasite crystals on a matrix of beautiful pink hureaulite tablets. Dan obtained this sample directly from Bill Roberts who described the species. This sample is illustrated in Photo Atlas of Minerals 2007, Rocks and Minerals 5/2000 and in the Encyclopedia of Minerals 2nd edition 1990, color plate #40. Comes with Dan's original 6 slides and index card. 

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.
