Had some fun with some thick malachite slabs yesterday.  Made these three 'faceted' cabs.

I used a diamond flexible Nova wheel for final sanding and then polished with tin oxide on leather.  I've already made a setting for one of them.  It needs final polishing and stone setting, and then I'll post a photo of it.

Here's the Argentium setting.  The inside surface was patinaed.  Sorry about the lack of focus for the photo!

I have a small piece of malachite very soft

I generally don't stabilize malachite.  It is very soft, so you have to keep that in mind.  Generally you can skip multiple sanding steps and go directly to a very fine grit.  Use lots of water as the dust is high in copper that you don't want to be breathing, and also the stone can form black 'burn' marks if it gets too hot while sanding/polishing.  Final polish I use tin oxide on leather, but sometimes touch up a bit with Zam on a muslin buff with my rotary tool.  Again don't let the thing get hot.
