Silver filled lobster clasps are a great option when you want to make silver jewelry but don't want the cost of solid sterling silver. These clasps are finished with a thick layer of 925 silver that is fused to a core of less costly metal. The silver overlay is hundreds of times thicker than a plating, which is why we consider our silver filled jewelry findings to be precious metal accessories. Silver filled lobster clasps are a popular choice for finishing the ends of necklaces.
