Description
This listing : 20 pounds rough midnight lace Obsidian with straight to squiggly black zebra type stripes. Each one is different in shape & pattern. Soft ball to baseball sized chunks. For medium & smaller saws. Midnight lace also was called black lace. Has nano Magnetite particles & other minerals in it. The pictures of slices are for example only. I slice midnight lace thinner than other rock slabs so it shows light through it. It can also be backed with color or metals. Makes great jewelry. Glass cuts & shapes easily but you need to not be overly aggressive in grinding. This will prevent tiny hair line scratches later. These take away from a super high polish. Finish with cerium. Also makes great light catchers in windows. Follow us on FB & Instagram Caldera rock shop. 20lb Midnight Lace Magnetite Obsidian, Softball Sizes. Black Stripes
