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 consists of a spring-loaded mechanism that allows it to open and close easily, providing a secure way to connect two ends of a chain or cord. These clasps are typically made from metals like stainless steel, brass, or sterling silver, ensuring durability and resistance to tarnishing. They come in various sizes and designs, making them versatile for different styles of jewelry. Many people prefer lobster clasps for their reliability and ease of use compared to other types of clasps.
