Malachite Azurite Native Silver pseuodmorph botryoidal chrysocolla

[Agateyes]

Hello all,

 

      I need help identifying a piece I was inherited recently.  My best guess is a combination of Azurite, malachite, native silver, botryoidal chrysocolla, and some type gemstone imbedded in the azurite main specimen, with who knows what.  I could be way off, but I’m going off similar pieces of my collection and knowledge.  The top has an interesting metallic botryoidal effect around the main specimen.  I am unsure of the location and it has some weight.  Thanks in advance for your consideration and assistance,

Wow,  I love it,  but I just do not not have the Geology smarts to figure out and answer.  I barely recognize the botryoidal chalcedony with a touch of druzy fossils that I find... Some members do understand the geology and will come along...

Hi, nice specimen. I'm thinking that purple is likely fluorite. The photo is not quite focused enough to see the crystalline structure well. Perhaps another attempt at that area to sharpen up the image?

 

Or they could be azurite or even purple calcite crystals...or maybe I'm not sure what you are trying to identify but think you are referring to the purple gemmy mass?

 

If we could get a nice zoom into some of the individual crystals that would be helpful.

Hello and thank you for the response.  I was trying to identify the purple mass that is pseudomorph metal of some kind, I think.  I misspoke about the botryoidal chrysocolla, it was for another piece.  The specimen looks to have azurite, malachite, native silver and copper, I’m not sure what else, some looks like gold.  I will get some better pictures loaded, it was high winds today, I apologize.

Relying solely on the colour of minerals leads to errors. We have to determine the crystal system to go further.

 

No doubt about azurite (which some see purple, but it’s intense blue in reality). You can see the shape of the crystals. For green the most common association is indeed malachite, but chrysocolla is not excluded.

 

Sur ta photo n° 9, on pourrait deviner que l'azurite recouvre un cristal indéterminé, ce qui arrive également en minéralogie. In the future put numbers to your photos, it will help in the discussion.

 

About metallic minerals (gold, silver etc) I do not think I see traces.

cooper minerals, hematite and possibly some cubic galena (guess base on  pics, associated minerals and experience)

The outer surfaces with the traces of malachite and azurite remind the stuff that comes out of Morenci, Arizona, but none of my examples from there have such an interesting cavity/vug. It's a keeper!
