This was listed as peacock ore.  I can see one area ( top ) that appears to be extra heavy with copper, but I don't think it is enough to be labelled as Peacock Ore.

It seem much more like a chrysocolla mix of copper, azurite, and dendritic tenorite. Unless what I think is tenorite ( black ) is actually just more copper.

Looked interesting enough to give it a whirl !

In my youth, peacock copper ore was usually chalcopyrite with the rainbow patine that it produces as the sulphides reacted with water. Perhaps that description no longer applies.  dunno

I remember Don..

Like everyone else, it can appear beautiful looking to us at first only to be disappointed after cuting into it and literally falling apart in the saw. Sometimes no matter how thick I cut them, even up to a 1/2" they have still fallen apart.

Even if this does slab ok but ends up being sort of questionable, might have to use something as backing to make sure it stays together before cabbing.

Guess will find out !

bummer.  bricks The best cutting chrysocolla I've found so far is the sonoran and narcozari stuff. Have had some good peruvian stuff too.  I've cut stuff from Ray mine and Inspiration mine but both tend to need heavy stabilization unless they are well silicated, which is not very often.

Thanks Don..

The seller was nice enough to refund..  I have been looking for a nice chunk of the Sonora, but gosh..., am I mistaken that it has sky rocketed in price over the past few years ?

I do not remember paying as much as they are charging for it now.. 100+ dollars for some pretty small chunks of just the average stuff.. The really nice bright, distinctive black, red, and blue pieces are running 150/200..
