This is one of the very finest (for its size) of the herringbone-type coppers ON MATRIX from this amazing find! It soncists of very finely-crystallized "feathers" of iridescent copper perched delicately but firmly on gray rock matrix at the base. Each end of each feather sticks out, freestanding, into the air. NO DAMAGE and tremendous aesthetics make this a significant copper, not merely just a good locality piece. BETTER In PERSON, of course... 8.5 x 3 x 1.5 cm
