It looks like Assyrian or Old Persian cuneiform to me, but I can't tell much else about it. It does look as though someone made the marks by hand...
here's the wikipedia page about variations of cuneiform, maybe you can compare the marks to their alphabet charts.

Thank you! Comparing the two, I don't really think it's cuneiform, though it is so similar. :/
I talked to my friend. She knows absolutely nothing about it except that a ten-year-old Russian girl said it was very special and gave it to her after my friend had given her a Bible. It's probably just a little stick figure, but I might look into having a jewelry expert (if that's even a thing) examine it.
Thank you everypony for your help!
