This native copper specimen from Michigan features unusual and complex dendritic growth - uncommon for specimens from the locality or for any copper from anywehre, for that matter. A mix of crazy elongated copper formations, many at sharp angles, weave and overlap like woven fabric, with bright luster. Ex. Kay Robertson collection, No. 11932. Kay was a prominent California collector, who specialized in European classics. To learn more about Kay, you can view this article in the March-April, 2007 Mineralogical Record ( https://www.mineralogicalrecor... ). This is a piece that just gets more and more fascinating, the closer you look at the detail.
