A piece of jewelry is only as good as its clasp. Often overlooked, the closure is one of the most functional — and quietly elegant — details in fine jewelry design. At CINCO, every component of a piece is considered with intention, and the clasp is no exception.
Whether you're shopping for a delicate chain necklace or a layered bracelet stack, understanding clasp types helps you make a more informed choice — and ensures your jewelry stays exactly where it belongs.
The 5 Main Types of Jewelry Clasps

1. Lobster Clasp
The lobster clasp is the most widely used closure in contemporary jewelry. Named for its resemblance to a lobster claw, it features a spring-loaded mechanism that opens with a simple push and snaps shut securely.
Best for: Necklaces and bracelets of all weights.
Why we love it: Reliable, durable, and easy to operate with one hand — a true everyday essential.
2. Spring Ring Clasp
A classic in fine jewelry, the spring ring is a small circular clasp with a sliding mechanism. Subtle and lightweight, it sits almost invisibly on delicate chains.
Best for: Lightweight chain necklaces and minimalist styles.
Why we love it: Its discreet profile keeps the focus on the piece itself — perfect for the CINCO aesthetic.
3. Box Clasp
The box clasp is a two-part closure where a tab slides into a box-shaped housing, locking flush against the piece. It creates a seamless, flat finish that blends into the design.
Best for: Tennis bracelets and chain bracelets, line necklaces, and multi-strand pieces.
Why we love it: Sleek and secure, it disappears into the jewelry — ideal for pieces where continuity of design matters.
4. Magnetic Clasp
The magnetic clasp uses opposing magnets to snap together effortlessly. No fiddling, no frustration — just a clean, intuitive closure.
Best for: Everyday bracelets and necklaces; particularly helpful for those with limited dexterity.
Why we love it: Effortless to use without compromising on security or style.
5. Fish Hook Clasp
Also known as a barrel or torpedo clasp, the fish hook closure is a two-part system where a hook slides into a decorative housing. Often ornate, it becomes part of the jewelry's visual identity.
Best for: Pearl-style and heritage necklaces, beaded strands, and statement pieces.
Why we love it: Thin, elegant, and visually seamless — it elevates the piece rather than interrupting it.

The right clasp depends on three things: the weight of the piece, how you'll wear it, and your personal ease of use.
