Native Copper Keweenaw Co., Michigan 9.9cm x 8cm x 5.3cm Ex. Thomas F. Cole Collection (1862-1939) Ex. California Institute of Technology Collection No. 1005

Description/Interesting Notes: A magnificent and unique old time native copper from Michigan!!! This specimen is from the collection of famed copper magnate Thomas F. Cole (1862-1939) and retains an old label (with Cole collection notation) from the California Institute of Technology Collection!!! This unique and aesthetic native copper specimen consists of numerous, isolated crystals scattered across its broad face!!! This is very unusual since most native copper specimens from the region tend to be more-or-less intergrown groups of contiguous crystals!!! I must note that these crystals are much sharper than they appear in the pics!!! The isolated crystals range in complexity from sharp single crystals to "balls" of interpenetrant crystals that show numerous sharp, square-shaped faces surrounded by more complex faces!!! Upon close inspection one can see that the native copper is quite well crystallized throughout!!! The crystals have a stunning patina that ranges from brassy-golden to a lively red!!! The matrix is covered with tiny, gemmy quartz points (many of which have copper inclusions upon close study with a loupe or scope)and there are some unusual, unidentified deep blue microcrystals scattered about as well!!! This specimen is simply INCREDIBLE in person - you simply do not see native copper specimens with such presentation!!! Thomas F. Cole had unprecedented access and means to acquire the finest native copper specimens Michigan produced and it is easy to see how this unique specimen caught his eye!!! This specimen is in fantastic condition all around and displays stunningly in person!!! Simply an amazing, and historic, old time native copper specimen!!! Don't miss out on this valuable beauty (its previous price was well into the four digits)!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
