^^disagree, clearly river worn diamonds.

But seriously, crack them open, you maybe lucky and find a fossil inside!

Yeah, goofs aside these are just river pebbles. Surface weathering can yield really deceptive colors and patterns, but they look a bit quartzite ish. That said, sometimes these stones can yield interesting cabochons. I've cut a few I collected from drain gravel at college which turned out neat.

Yeah, I took some to my mineralogy professor when I was a freshman and that was what he told me. When I cut them open most lookes veey different inside.

Absolutely, if you like them keep them. If you get a saw in the future slicing them through the middle is a great experience too.
