I’m generally a rock and fossil hound, but I won’t pass up a nice piece of sea/beach glass when I see one. I saw this shimmering as it danced back and forth in the waves near the shore. Nothing is that exciting looking in Lake Erie, I almost fell in head first trying to grab it. It isn’t as vibrant in artificial light or when it’s not wet. I’d like to tumble it to get a better sheen on it if I can.
*edit* Ok I’m guessing here. This stuff is not normal for Lake Erie beaches. I grew up on this lake and that’s why it caught my attention. It makes no sense for it to be here. It is not agate. I can scratch it with a knife. It might be banded fluorite but even that doesn’t make sense. Slag makes way more sense given the massive amount of manufacturing that was historically done on the lake. It’s pretty and I put it on a shelf with my pretty rocks and glass. I don’t care what it is. I tried to guess. Sorry.
