Welcome, Michelle NYC,
We need to see more of your necklace, please! It does look interesting. What are the marking on the clasp~the insert part? Also please show more of the pearls. And if you could adjust the exposure so the pearls are more like in real life, that would be great.
The clasp could be 14K, as it has a safety catch, but the character on the clasp probably isn't related to the actual maker.
