Red Branch Coral Claw Necklace

Vintage necklace of red branch coral in a claw design. Measures 18" long. Longest "claw" is 1 1/2" long. C. 1960s. Coral is somewhat chalky from age. I did clean and oil it with olive oil, but it could use a few more oilings. Weight: 14 grams. Clasp appears to be sterling silver.
