First of all. I don’t know if anyone made Black Slags. I have louped the flea bites. I’ll venture out but I think Some black glass in this one. I have no idea on the ID. It’s 3/4
It’s probably one of the few Mint marbles I have. Under 30x loupe there is one extremely small flea bite. I think this would probably knock it out if being Wet Mint.
Yes. Second picture from right to left shows the purple go from dark transparent purple to a semi transparent purple. The thin ribbon is what has me stumped. A blue dominated purple. I wish my pics were better to show the blue the thin ribbon.
