Ideal for use with pearl and gemstone strands, this 18-karat yellow gold round safety clasp features an eye-catching open twist pattern with a smooth bright finish. Its elegant styling makes it a great choice for a wide variety of necklaces and bracelets. Designed for single-strand use, the shape of this secure closure blends seamlessly into a strand of round pearls. Safety clasps (also called pearl clasps) feature two parts that connect in two different ways, providing a fail-safe that helps prevent loss of higher-value necklaces or strands. The interior part of the clasp is a slender hook with notches along the outer edge; the exterior part is hollow except for a locking bar. The interior part hooks over the locking bar and then slides inside the exterior part, the notches catching along the inner sides to hold the clasp securely closed. Even if the notches fail for any reason, the hook keeps the strand in place.
