After some tests, I believe I have a giant chunk of Specular Hematite with white and blue quartz
I did some tests to figure it out, scratch test, vinegar test, 365nm UV light. Its quite heavy, and has a massive scheen that runs across it when you turn it in the light at different angles. I finally chiseled and broke a chunk off of the big piece to see what's under, I cleaned it and it looks a lot like little mirrors everywhere and brown/red on the side for the layers of the shiny Specular Hematite.
the white and blue chunks coming out of the back and side did not react to vinegar and scratched the ceramic without leaving a mark. the reddish brown hematite left a reddish brown streak on the ceramic, but just barely, it scratched the ceramic a bit before it left a mark. The UV light didn't cause the bluish and white protruding chunks sticking out to react or do much other than reflect the light.
I don't know for sure where it's from, I got it from someone who said their grandparents brought it home from one of their vacations in the 70s. Might be somewhere around the meramec caverns/ozarks area in the USA, as I was told they went there a lot, but wasn't certain if that's where it came from.
Several pictures of the big main rock, front and back. I got a picture where I chipped some of the lip off. There's several pictures of after I cleaned the pieces I broke off, both side views, close ups, and different angles on the main face of them.
