Vintage Zuni owl ring with turquoise, penn shell, mother of pearl and jet. Unsigned. Circa 1970's.  Personal note: When my children were little they thought the top 'brows' were mortar boards for graduation, so we called them 'Graduation Owls' and I gave each of them one when they graduated. 

Size: 6.5

Face of ring: 3/4" x 1 3/4"
