d_day Posted January 9, 2019 Share Posted January 9, 2019 Looks like a mix of many things. I see what looks like malachite, chrysocolla, and some azurite. Can't tell what the brown is. Quote Link to comment Share on other sites More sharing options...
adam Posted January 9, 2019 Share Posted January 9, 2019 Yeah, its a mix of several minerals .....Better pictures would help . You didnt get a label when you purchased it? Do you remember where the specimen was from? Quote Link to comment Share on other sites More sharing options...
4meter Posted January 9, 2019 Share Posted January 9, 2019 Looks like the brown/pink material is Calcite. Very pretty piece! Quote Link to comment Share on other sites More sharing options...
Liso Posted January 9, 2019 Author Share Posted January 9, 2019 Thanks for the responses. There was no label. Purchased at a small gift shop. Could the brown be iron? I'll post higher res photos today. Quote Link to comment Share on other sites More sharing options...
Morlock Posted January 9, 2019 Share Posted January 9, 2019 Yes, the brown staining could be from iron but it's not an iron mineral...just staining. Nice specimen. Quote Link to comment Share on other sites More sharing options...

Liso Posted January 9, 2019 Author Share Posted January 9, 2019 (edited) Could this be torbernite? It looks like there is a cloudy surface on the minerals which is why I tried to wash it with water. When I did wash it, my hands began to burn and hurt. They were like that for about an hour. Then that night my left hand swelled :( any insights? Could they have washed it with toxic chemicals?

Red_desert Posted January 9, 2019 Share Posted January 9, 2019 (edited) That is different than anything I've ever seen. There is a mineral they used to treat with toxic chemicals, to make it look like peacock ore a type of copper mineral. The color must have come about as a reaction to the chemicals... might have even been a type of acid. It would have to have a bluish/gold sheen I think.

clay Posted January 9, 2019 Share Posted January 9, 2019 Pictures are a bad way to identify minerals. It appears to be copper mineralization on calcite but only testing will tell for sure. If you have a collection locality it would help a lot. I doubt it's Torbernite. Torbernite is very rare and doesn't survive long in air/sunlight, I've still to find a good representative crystal. Your specimen does have some of the characteristics found in some deposits. Torbernite is a secondary mineral of uranium deposits. Torbernite is only mildly radioactive so I doubt it could hurt you from washing in water. Try a Geiger reading - if it isn't radioactive it isn't Torbernite.

Bob(AK) Posted January 9, 2019 Share Posted January 9, 2019 Very strange looking for sure, if the brown is calcite easy to tell. We have been talking zeolites, could the stained brown be stilbite or something similar? Quote Link to comment Share on other sites More sharing options...
