Vintage 14K (or 12K) gold filled Victorian Conch shell Cameo pendant

Vintage handmade gold filled filigree pendant. With a real authentic lady's head Cameo, hand carved from natural Conch shell. Stamped F.S.G.F. Back in the day, the gold filling was most commonly done with 14 karat gold, and sometimes with 12 karat gold. 1" long (with bail). In excellent condition, as pictured. Gold filled vintage jewelry is considered valuable and collectible as it tends to be of better quality and also contains quite a bit of real gold.
