Description

Unfortunately no exact locality from this historic old mining district is given with this specimen which features beautiful pink rosette style crystals that were obviously part of a larger vugh in the pyrite rich matrix. A couple of galena crystals can be seen amongst the rhodochrosite to add a little extra interest. Best viewed with magnification to appreciate everything here.
