Barrel Clasp: Used on most rope chains to make the chain more secure. The barrel clasp looks like part of the chain and twists to get a pendant on and off.

Lobster Claw Clasp: As a traditional clasp style found in bracelets and necklaces, the lobster claw is generally reserved for heavier styles that may need added strength. The closure's shape is more oblong, similar to a teardrop shape, and is controlled by a tip that opens and closes the spring in the clasp.

Magnetic Clasp:A magnetic clasp relies on a strong internal magnet that works to pull both ends of the clasp together. In most cases, a magnetic clasp is used for light to medium weight jewelry pieces that do not put excessive stress on the magnet.

Slide Insert Clasp: This type of clasp is exactly as it sounds. With a box-like shape that is hollow on the inside, the wearer will slide the nearly-flat tab into the box until it clicks, indicating a secure closure. On some jewelry, a slide insert clasp will be accompanied by a side safety catch, which adds strength and security to the clasp.

Spring Ring Clasp: One of the most common closure types, the spring ring clasp is typically used for light to medium weight bracelets or necklaces. It is round in its design and features a small tip which controls the opening and closing of the spring. The circle then closes around another smaller loop or link at the other end of the strand.

Toggle Clasp: A toggle clasp is a narrow piece of metal, usually designed in the shape of a bar, which is then pushed through a circular ring to act as a fastener. Unlike the lobster claw or spring ring clasps, a toggle clasp is not controlled by a spring. The pretty design is less secure than other closure types, but is usually meant to be a big part of the design and is meant to "show". The clasp is an attractive way to secure a chunkier link bracelet or necklace.

Bracelet Sizing
To measure for a bracelet, wrap a soft, flexible tape measure around your wrist bone. Then, add 3/4" to 1" to that measurement to determine your bracelet size. Generally, 7" is considered a standard women's size and 8" is considered a standard men's size.

Another way to get an ideal fit is to measure the length of a bracelet you own. For bracelets that are to be slipped over the hand, measure the widest part of your hand to ensure the bracelet will fit over it.

Keep in mind that different bracelet styles tend to fit differently depending upon the clasp and materials used. Bracelets with adjustable clasps are usually one size fits all. Those with large beads or stones have less room for your wrist. Also, bracelets with links can usually be shortened by removing one or more links.
