These are not your Grandmother's pearls! I never offer faux pearls, but I couldn't resist these ones. They are extremely good quality, not the kind that flake and peel. These ones have the most beautiful nacre and the length is so impressive at 40 inches long. I had the beads re hand knotted with silk cord.There originally was a platinum clasp with diamonds on this necklace, but I couldn't justify the price for a faux peal necklace so I added an appropriately aged clasp in silver instead. The pearls graduate is size from 4mm to 8.5mm. The nacre is a very pleasing yellow tones. The clasp is marked 935 for the quality of silver. It has 2 tiny genuine pearls on it. Condition is very good. C. 1920 and American in origin.
