This item is (1) 10mm long x 4mm wide Gold Filled Lobster Claw Clasp. Great for use with a Split Ring or Jump Ring. These Clasps are Gold-Filled NOT gold-plated. Stamped 12/20 GF. Gold-filled findings are a base metal with 12K Gold heat and pressure bonded to it. Unlike Gold plating, it will not wear or flake off. The Gold you see is indeed 12K gold and the findings tend to hold up better than pure 12K ones due to the strength of the base metal center.
