I need some help identifying this necklace

I’ve never used this site before, but was wondering if anyone could help identify this necklace. I purchased it from an estate sale and I believe it’s a vintage Hopi piece.

Looking through Margaret Wright’s Hopi Silver book the hallmark is attributed to McBride Lomayestewa. It has him active from 1955 until 2002. This is a google search for his name https://www.google.com/search?q=mcbride+lomayestewa+hopi+jewelry&noj=1&source=lnms&tbm=isch&sa=X&ved=0ahUKEwitpt7axsDTAhVFs1QKHeALDmsQ_AUICSgC&biw=1920&bih=1044. Thanks for sharing.

Wow, thank you so much for your help!!
