Victorian Silver Locket

This is a silver locket marked with a lion and an h, which makes it British silver and it is also marked BBros on the back with another set of hallmarks, which unfortunately have worn away. I do wonder if the coloured flowers and leaves are gold. I have had this locket since I was a little girl, as it was in my Nana's button box, and she eventually gave it to me. I think it was fairly battered when I got it, but it is a lot worse now and the hinge has broken, but I wore it a lot in my youth, with a 4 leafed clover in it for luck.
