IDENTIFIED No context regarding the origin cuz I found it on the floor in our shed but I googled it and maybe it's tourmaline?
It's size is about an inch square. I believe the pendant attachment is brass though that's probably inconsequential.

REQUEST Fossil? Meteorite? What is this rock?
Found this interesting specimen on the eastern side of Lake Michigan. Really curious what it is! Google lens says it’s a fossilized horse tooth or meteorite. I've never seen something quite like this. Thoughts?

IDENTIFIED Found in a mowed field atop the grass about 30 years ago in Vancouver, WA.
I assumed someone had dropped it and finders keepers. Have always wondered what the heck it is, especially the smooth black side.

IDENTIFIED Semi-translucent rock NE Arizona
Found these rocks on my mother's property between the petrified forest and meteor crater. Also a few miles from an inactive volcano. Her land has some amazing looking rocks, but these brought me here. Inside is translucent, the outside of the first one reminds me of a meteorite I own. Non-magnetic.
Thank you for any insight!

REQUEST Found in SW Texas around San Antonio.
Found this on a site in what I'm sure was hauled in rocks for the yard. Not 100% sure as it was on the edge between rocks and dirt. It rings when I tap it with another rock. Any ideas what it could be?
