I got a box of copper conglomerates from vegasjames. I grabbed a small piece to try. On the 14k wheel, this still had a very nice and attractive matte finish. At 50k the high spots polished. Which I think is also nice. I have no idea what it is other than maybe chrysocolla. It has a true color close to emerald green with some Russian amazonite color thrown in. It was very soft and a challenge to cab. I imagine it is a lot like natural turquoise to cab- which I haven't done very much of. It's not something I would typically do, but I really like it. I love all the texture. I can see this mounted in a really cool silver setting. I need to take it to the flat lap to even out the bottom a little, but otherwise I am leaving it- unless I go back to the matte finish, not sure. The box was actually a mix of all kinds of copper things a lot of which look nothing like this. I'm anxious to try out some more. So what do y'all think - matte or polish? Imagine the color a bit more dark and rich as matte. Anyone seen chrysocolla like this?

Tela, I'm not sure what I'm looking at. Are they all the same finish, or different finishes? Please clarify. Thanks.

IF it were matte, it would obviously be matte, but the color would be a littler darker and richer. There isn't a whole lot of shine on it because the surface is so rough. This just happens to be very porous stone. I've never cut one with this texture, but I'm rather fond of it.

I think when you flatten the back you should then polish the back to matte. It will make it easier for you to decide. I think matte will win out

I kind of like that textured effect. Looks more natural that way. I have a cab somewhere that came off a hunk of copper ore I found behind a cafe in AZ. Finished with that dimpled effect and I kept it cause it was cool looking....Mel

I think Roger had a good idea about finishing the back first, but my inclination is to go for the shine.
Peace, Rich

That mine contains a wide variety of copper minerals. Chrysocolla, cuprite turquoise, malachite, dioptase and possibly rosasite and azurite.
The host rock is mainly dolomite and quartz. The browns to black are limonite, which is a generalized term for a mixture of iron oxides and hydroxides.
Looking at the piece it looks like the greens are malachite and the darker emerald green dioptase.
Have not come across any pieces with that texture yet.
