Lobster clasp
A spring-loaded claw-shaped clasp, the most common closure used on necklaces and bracelets.
A lobster clasp is a small metal clasp shaped like a claw, with a lever on one side that, when pressed, opens a spring-loaded gate so it can hook onto a jump ring or chain link. Releasing the lever lets the spring snap the gate shut again, closing the loop securely.
Sizes range from small, delicate clasps suited to fine chain to larger, easier-to-grip versions used on statement pieces or for anyone who finds tiny clasps hard to operate one-handed. The clasp's finish, silver-tone, gold-tone, or antique, should generally match the other findings on the same piece.
When buying, check that the spring action feels smooth rather than stiff or loose, since a weak spring can pop open under light pressure. A common mistake is choosing the smallest, most delicate-looking clasp for a piece that will see daily wear, when a slightly larger, sturdier clasp would hold up better and still be easy to open.
