Did you cut this one yet CW?
Looks like there is at least one fracture you will need to avoid. Usually I would try to cut across the pattern to show the best play of color while avoiding any obvious cracks/fractures. I've also cut along with the fracture on some pieces which of course does remove most of the fracture with the cut. The idea is to make a piece usable for the desired cab shape(s) you have in mind. Typically a cab blank will be about 3-5mm or so slabbed, but I've worked small pieces such as this with only 1 side (back) being flat. It's a bit more work tryin to rough the shape of the uneven top into a dome but it can be done. What is the material? I'm gonna guess from the photos that it is Malachite.
