| i've had obsidian roll out of my yard before & there's a BIG difference between rough obsidian & scuffed/slightly tumbled obsidian. in fact black obsidian will cease to resemble glass as soon as you first start tumbling it. it will gray out a bit & look like dull black rock when it's dry. to get it really glassy again, you have to tumble it completely smooth & use polish on it. in my opinion polished obsidian looks like rough's poor relation in comparison--only a shiny black rock instead of true glass. the difference sounds subtle, but if you lay them side by side there's a purity in the raw glass that gets lost under the polish. the only point to tumbling obsidian is to get the knife edges off it. | ||||||||||||||||
