What is this?

Can’t tell from one photo. Can you post more at different angles?

I'll take a few more, unfortunately the quality isn't the greatest I currently only have a tablet to use. It's small in size, brown outside, smooth, but looks like the interior is made up of something else? (Greenish in color) I'm not sure if it is a rock or something else. I will post more pictures shortly.
