Mexican Jalisco Rainbow Obsidian Cutting Rough Box! Utah Wonderstone with some being the perfectHere is a gorgeous box of Mexican Jalisco Rainbow Obsidian! Some of them are high grade, some of them are gamble cutters! Each one is showing some form of Rainbow, but some have a skin covering them that makes it hard to see how they might cut! This is still a great price on this box, and with at least a couple high grade chunks, this is a batch you will for sure make more than your investment on! These are unpolished, uncut, and photographed wet.
