Antique Victorian Love Knot Mourning Brooch Central Black Stone w/Some Chipping - I think Jet (possibly Onyx or other, untested) Gorgeous Engraved Details Loop for chain, watch fob, etc. It was filed/notched to test for gold content at some point; I don’t believe it’s solid gold, but it has that appearance! (I haven’t done an acid test.) It’s a very lovely bright yellow gold with no evident plating wear! C-Clasp In gorgeous antique condition!
