A cast lobster clasp is a type of jewelry clasp that is shaped like a lobster claw, which is where it gets its name. It’s a popular and secure fastening mechanism used in necklaces and bracelets, especially in fine jewelry. Here’s how you can explain it to a client:

1. Design: The clasp features a spring-loaded arm that opens when you press down on a small lever. Once attached to the other end of the necklace or bracelet, it automatically closes and securely fastens the piece.

2. Casting Process: Unlike stamped clasps, a cast lobster clasp is made using a casting process, which involves pouring molten metal (like gold or silver) into a mold to create the shape. This process tends to result in a more solid, durable clasp with intricate detail.

3. Why it’s used in fine jewelry: A cast lobster clasp is often heavier and sturdier than other types of clasps, which is important when securing high-value jewelry pieces, ensuring that they remain safe during wear.

A cast lobster clasp is a high-quality, reliable option that enhances both the security and aesthetic of fine jewelry.
