Valuation of Prestige Pearl Necklace

by Paul Rocca
(Bonita CA., USA)

I have a Prestige hand knotted two strand set of pearls with a sterling silver clasp. The clasp has 3 additional pearls in the middle on the clasp and also has diamonds or rhinestones in the clasp design. Could you give me an idea of what they may be worth? Also in the original leather and satin case.
