Are these rocks safe (Pics)

I want to make sure these are safe to use and can the rocks be to sharp to cut my beardie?

They seem a bit sharp to lay flat on. I probably wouldn't add them... The brown one might be ok though. Is the dark purple stone Fluorite?

I wouldn't put something that sharp in with a beardie just because it is better to be safe than sorry. We found nice flat, smooth ones in a river bed, bleached them, baked them in the oven to kill anything and our beardies have loved them for months. Didn't cost anything except time.
