Vintage Ear of Corn Ring Spiny Oyster Zuni Bev Etsate Size 9

Big vintage ear of corn ring with hand carved spiny oyster. It has inlay dots of turquoise, lapis, malachite, coral and jet. Face measures 1 7/8" by 1 1/8". Size is approximately a 9 to 9 1/2 . The shank is not a perfect circle, flat side under the setting makes it hard to slide onto the mandrel. It weighs 18.1 grams. The shank has a pretty overlay design.  Signed BE for Bev Etsate Zuni on the back. 

I have three rings from this artist and from the same estate. You can see them in the last photo. They are offered separately.
