  • This is a great geological ans well as mineralogical specimen. It shows four different, parallel, sheets of copper in shale fragments. Now the largest one that you see is dominant but there are three other parallel sheets in the specimen! Very cool.

  • Largest Crystal Size: cop-20mm
  • $150.00
  • White Pine Mine
  • Ontonagan County
    Michigan, USA
  • Now this is an odd one! There are opening in this odd matrix that are lined with tiny, green, sparkling epidote crystals. An odd habit of copper has formed on the epidote is sort of shaggy, radiating aggregates of copper foil. Sort of. Either it is some weird sort of copper crystallization or it could be some sort of epimorph of copper after an earlier radiating mineral. In some areas, the epidote is crystallized on the copper. There are also vugs of tiny adularia or datolite crystals on the back of the matrix. Unusual and interesting!
