Vintage Zuni Red Coral Petit Point Post Chandelier Earrings Signed Bill & Lou

Beautiful pair of unusual red coral petit point earrings. I have not seen another pair like these by these talented artists for sale. A bit tarnished by age, I have not tried to clean the silver. I bought these beauties for myself but have only worn them a few times. Size is approximately 2.25" at longest x 0.75" at widest Please ask any questions.
