james avery

Got this on one of the local Bay beaches in shallow water with my Equinox 600. Came in a steady 30 -31, nice high tone.

This is a retired James Avery charm/pendant. I can find no info on it. There is not one like it posted on eBay that is current or sold. Seems to be vintage James Avery with how it's made compared to the more modern pieces. Any ideas on its name? Years it was made? Value?
