Mexican Stone ID

After reading all the Mexican stone comments I pulled an old definitely Mexican stone and brass box that I’ve never been able to identify. No stamping. What is this stone?

 

Mexican stone ............... sorry...that's all I got !!

 

It's what geologists would call a rock: a mix of different minerals. Some of it is probably malachite. Could you back off & take a photo of a broader section & try to minimize glare?

 

That’s been workin’ for me for at least 20 years lol! I’ll go take some more pics now but that photo is really what it looks like. No idea here either but it’s a great old box.

 

What tends to turn up in searches are collectors' specimens. Not at all saying this is what yours is, & yours has more than 3 minerals included, but this is the sort of thing:

From the photo it looks like a number of copper minerals in matrix,something like the photos in the link... http://www.greatrough.com/rough_chrysocolla.shtml

 

Thanks all. That makes sense to me Hollyblue. Definitely a lot of stuff in a matrix.

 

Definitely a tossed salad of stuff. Brightening up the colors a little:

 

Oops, posted faster than photo could load.

 

I call that material RPR - random pretty rock. The Indians do similar things - random bits of chrysocolla variants in a matrix that may be natural and may not. It does its job and acts like a box. Cigarette box maybe?

 

I think too large. I guess maybe cigars-wood lined and at least 18” across but I’m not home now. Thumbs up on RPR!
