AAAA quality pearls represent only 2.5% of the annual pearl harvest. Each pearl is a rarity in itself, representing the highest quality available anywhere. The necklace offers an amazing variation of colors that exemplify the beauty of South Sea pearls. Each pearl is carefully hand-picked and matched precisely according to the "theme" of this pearl necklace. All pearls are AAAA in quality with gorgeous overtones and "Superior" grade luster, our highest grade available in every category. The necklace is strung and double-knotted with silk thread and comes affixed with our standard 18K white gold ball clasp. Necklace lengthening and premium clasp options are available at checkout.
