These Brand New Rope Chains are 100% GENUINE 10K YELLOW GOLD and are STAMPED 10K. These chains are REAL GOLD, they are NOT PLATED, NOT FILLED. These chains have a lighter feel, but rest assured these chains are still entirely made of 100% Pure 10K Gold. These chains fasten with a 10k Yellow Gold Lobster Clasp that is very strong and easy to use (1.5mm version features a Spring RIng Clasp). These chains can be layered, stacked, worn on their own or with a pendant. These high quality rope chains will not tarnish or discolor as they are Pure 10k Gold and MADE IN ITALY. The high precision diamond cuts on these chains give them more shine without compromising their smoothness and overall comfort.
