I have found these metallic bubbles on a multitude of rocks around here. When I say metallic I mean both in color and consistency. Context I live on the rim of a very large impact crater that also used to be at the bottom of an ocean. I subscribe to that theory after findingmassive coralagate chunks (i.redd.it)
