CORO Pegasus (DES.Pat.Pend.) Silver Leaf Necklace

Coro necklace with entwining silver leafs and "j" hook. This necklace is marked with CORO written in script, Pegasus beside it, then underneath, DES.PAT.PEND. I almost went blind trying to make this out! It is an extremely old piece, very gently worn. There are 2 flaws that I can see. On two of the leafs, there is a "pin head" size flaw where the silver has rubbed off. Very minute. This Coro necklace is approximately 17" long. Exquisitely beautiful! Thanks for looking.
