This stunning double strand of 7.5-8.0 mm pearls is composed of near-round (AA+) quality pearls. The pearls' surfaces are virtually clean of any imperfections and exhibit high luster. This 17 and 18-inch nested strand is double-knotted on silk and finished with a polished 14-karat, square-style clasp. If you prefer the double-strand necklace to be a bit shorter or a bit longer, please let us know. We would be happy to customize this piece to your exact specifications.
