Vintage solid 14K 583 rose gold woven chain necklace in mint condition from Soviet era circa 1980. Length - 26 1/2, weight - 5.7 grams, thickness - 1.5mm, nice and sturdy. The beauty of the vintage Soviet gold marked 583 (equivalent of 14K) is that USSR jewelry factories followed strict requirements not only for the gold content, but also for other alloy components.
That special alloy was created to make gold jewelry more durable.
