Victorian gold filled ruby mourning jewelry braided hair Pocket watch chain

Absolutely gorgeous mourning watch fob chain cord made from their loved ones hair braided, marked F&B 1-10 so I'm guessing it's 10k gold? Once I test and if it's 10k gold the price will double. Doesn't appear to have any peeling areas like gold filled or rolled gold looks after a while so I'm hopeful it's all gold. Has a tiny bit of fingernail polish on hair that's why it's red looking.
