Victorian 10K Gold Hand Carved Cameo Pendant Necklace Carnelian Shell

This very pretty Victorian hand carved cameo is set in an unusual 10k Gold (marked on the bail) filigree rectangular frame. I believe it would be from between turn of the 19 and 20 century. It could be a bit older. The setting is a lovely floral Victorian style pattern. It’s a sweet, lovely piece. It is marked 10K . Total approx 1-1/4 inch on the long side. It would make a lovely gift. The piece weighs 4.2 Grams
