Lobster Clasp

A lobster clasp is a popular, self-closing jewelry clasp that resembles a lobster's claw, featuring a spring-loaded lever that opens the claw to attach to a jump ring or chain link.

This clasp type is one of the most secure and reliable closures used in necklaces and bracelets. The spring mechanism keeps the claw tightly closed until the lever is pressed, preventing accidental opening. Lobster clasps come in various sizes from tiny delicate versions for fine chains to large decorative versions for substantial jewelry.

Quality lobster clasps should have strong springs that don't weaken over time and should be sized appropriately for the jewelry's weight. They're more secure than spring ring clasps and easier to operate, though they require two hands to open and close.
