Black zebra agate rough from India is a rare and unique agate with irregular black and white stripes. (Stock 220) A small amount of red may be visible on some rough with the black and white stripes. Most of the rough is in large sizes from 5 pounds to 100 pounds per piece. If you need a smaller size rough, it can be saw blocked at a cost of $.50/square inch if we get your permission in an e-mail since this will require additional funds on your order. We have flat lapped some beautifully polished heels using black zebra agate. Not sure if this new material has to be polished with diamond, but the beautiful designs and patterns of black zebra agate are quite nice. See a sample of Indian, black zebra agate slabs.
