Help with rock ID

[sgtled3533]

Hello all. First time posting in the geological forum. I'm a metal detectorist and have just returned from a hunt at a local park. Found the usual clad coins and tons of junk. However, the most interesting find of the day (in my eyes) is this green stone wrapped in silver strands. It definitely looks homemade, but the metal tested positive for silver. That aside, I'm more interested in the green stone. I'm guessing it's nothing amazing, but I'd still like to ID it it's got some nice details to it. Someone liked it enough to wear it around! Thanks in advance!!

Malachite

Thanks for the detailed description hahaha! Much appreciated! I'll research the stone and see what it's all about.

No problem might as well just look it up, but in short it is a copper mineral for the most part. Pretty soft so keep it away from metal or it will scratch easily. if you want to polish it up, use tin oxide or chromium oxide on leather.

Malachite indeed. The method used here to set the stone is called "wire wrapping". Quite popular some years back.

Banded malachite. CuCO3 (Basic Copper Carbonate). Not as common to find in nature since people used it for large-scale green paint production. But they stopped using it.
