Copper Replaced Petrified Wood

This piece of Petrified Wood has been replaced with Copper rather than Agate. Then, oxidization occurred to bring out its green color, resulting in this interesting and rare specimen of wood.
Winslow, Arizona 

Please note there is some mineral tack residue on the bottom (see last image). We recommend placing new tack here to prop mineral on display
