Antique Victorian Pendant With Hand Carved Conch Shell Cameo

Gorgeous and rare antique Victorian pendant. The Cameo is hand carved from a real organic Conch shell. The metal composition is unknown and looks like two tone gold - yellow and pink. Can't find any marks, so it could be rolled gold (with 10K or 14K gold foil), or gold filled. But it does feel as there is some karat gold in it, especially on the top layer. On the sides, the intricate metal layering is visible, with three layers in some areas. This is a very unique and rarely found antique workmanship. 1.5" long (with bail). Has some signs of age, as pictured, but still very beautiful and pleasing to the eyes.
