I recently acquired this piece, the seller claimed it to be VICTORIAN 22KT SOLID GOLD ENAMEL PANSY. I don't see a jewelry mark, though the seller claimed there is one on the clasp, which is so small I can' t make out if it is a dent or a mark. See pic 4. It weights about 10.4g. Is this a truly Victorian piece? Is 22k common during that era? Much appreciate.
