Description/Interesting Notes:
A terrific example of native copper from Michigan!!! This specimen consists of a large cluster of thick, chunky copper crystals that host a
significant showing of epitaxial malachite!!! This specimen is SOLID and hosts some very well formed crystals!!! There are some
sharply defined faces present and the crystals are much better formed than the pictures show!!! This specimen was acquired in an old collection and
appeared quite curious - the surface alteration was quite significant and it appeared that there were other possible copper alteration
species present in addition to malachite!!! I first wondered if it had been treated in some way at some time, however the alteration was not uniform around the specimen and there
were even some unaltered areas - in addition there is some calcite present which does not show any kind of etching or alteration!!! Either way, it is a
significant, and handsome specimen indeed!!!
The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
