These pearls were passed down to me from my Aunt. At the very least, I know that they are over 40 years old but possibly order. The box indicates they were purchased from Cornell's Jewelers in Rochester, NY. The pearls are very iridescent in color and there are 80 of them. The clasp is filigree, and appears to be white gold. Their is an imprint that indicates 14K. Can you give me an idea of what kind of pearls they are and a ballpark of what they might be worth? Thanks
