Vintage Turquoise Petit Point Sterling Silver Signed Ring

This vintage Native American made ring is signed Peter and Vivian Haloo. Based on my research this is a Zuni snake eye petit point turquoise ring. Handed down from my Aunt, it sits in my jewelry box and I’m selling so someone can enjoy it! Based on a plastic sizer I have it may be a size 6. PLEASE NOTE: Close up pictures make turquoise look brighter than they are. Cover picture and second picture show coloring accurately.
