A lobster clasp is a type of fastener commonly used in jewelry, particularly in necklaces and bracelets. It is named for its resemblance to a lobster's claw. The clasp features a spring-loaded mechanism that allows it to open and close securely, making it easy to attach and detach from a chain or other jewelry components. These clasps are typically made from metals like stainless steel, gold, or silver, ensuring durability and resistance to tarnishing. Due to their reliable design, lobster clasps are favored for their strength and ease of use, making them a popular choice among jewelry designers and consumers alike.
