Vintage 1980s Givenchy goldtone O-link choker necklace. This substantial, elegant piece is designed with two alternating link styles: round O links with a smooth, high polish finish, and tripartite almost Roman numeral 3 links with a finely brushed / textured finish. It features a fold-over clasp closure, in good, strong condition. Near the clasp, the necklace is signed on the bottom of the interior an O link, "© Givenchy Paris New York” in an oval cartouche. Exterior diameter about 6.5", interior diameter 5". The necklace measures about 17.75” length (without the clasp) and 0.75” width, and weighs about 4.4 ounces--almost 125 grams. The necklace is in excellent pre-owned, vintage condition, showing little wear--the photos do not do it justice! Beautiful.
