Nice to see a new collector on this forum. But to be perfectly up front, I am skeptical.
What exactly does djurleite, chalcocite, malachite, azurite all together mean? Has your example been analyzed? Do you have any paper copy of its analysis?
And, copper wood, sandstone, Chinese formation, triassic?? The whole specimen description taken together just sounds gobbly-gook foreign to me. Maybe some expert can sort it out.
What is the specimen's locality? Without a specific locality, specimens like this have relatively little collector interest.
If that is what the specimen's label said, rather than putting it all into your posting, I would put the actual label itself in the photo along side the specimen.
And finally, are you sure it is all natural. Looks like it may have had some areas of its blue color enhanced or dyed.
Sorry to be so critical, but learning is gaining experience....for both of us.... BOB

Hello Bob. I’m glad you asked. The only thing I can really add to this is that it’s petrified wood. The collector I purchased it from wrote it up almost exactly the same as I did. I will upload a photo of the tag that came with the specimen. I hope this helps.

That label certainly helps. Note that it includes the specimen's locality in New Mexico.
Now it seems more legitimate, but if there is any question of all the copper minerals analysis is suggested. As to its colors, a 5 minute soaking in acetone should confirm whether its blue color has been enhanced or dyed. BOB

I apologize. I thought I listed the location, but I guess I never did.
You suggest I soak this in acetone?
First time that I’m sharing and I'm already learning! That’s awesome!
Thank you Bob! I will do as you suggested and let you know what happens.

Note that it's the Chinle Formation, not Chinese Formation. Probably an error caused by automated spelling correction software... I hate those programs! ;))
Nice rich piece anyway.

Oh oops! To be honest I wrote “Chinese”.
Am I able to edit that and correct it?

| I have many specimens with no background info. When I post them I’ll be hoping for help identifying as much information as possible. Can’t wait!

| I'm always glad to help, as are most members of the forum. However, there are some basic tests you should conduct yourself before posting "unknowns". Otherwise, we waste a lot of time with "back-and-forth". Please see the "General guide with rules and tips."

Please post these in 'For Beginners : What is it, where is it from', not this one. It will make for a far cleaner thread
