Zuni Necklace

This necklace and earrings were sold as a set. I bought these from a dealer in Carlsbad, New Mexico. The store was at the entrance to the park. Could anyone tell me about this necklace and its approximate value? The necklace is stamped
JY and marked sterling. Who is the artisan? Thank you!

This necklace was purchased around 1990. Thanks, Wolfetotem
