I don't think this is an artifact but it's an interesting rock. I have 2 pieces like the one I'm showing. It is covered in small, very metallic dots. I don't know how to explain. The black dots are very shiny. It's incredibly shiny but my camera will not show so I made the last picture out of focus on purpose so you can see the shine. The litt!e black dots do flake off of the rock. Just wondering if anyone had ever seen something like this piece. Thanks for any help!

Looks porous, like pumice or scoria, altho scoria’s “pores” bigger and not so uniform, but none of my pieces of those have mica or any shiny stuff in them. Maybe some form of Ga/SC red sandstone? Whatever it is, sure forum folks figure out. It’s very, very intriguing, not to mention cool!Digging in GA, ‘bout a mile from the Savannah River
