Necklace & Bracelet Clasp Types
A clasp is more than a practical device used to fasten your jewelry. It is part of the overall design and can be a very important focal point. Be sure to consider if it will suit your needs of durability, fashion, comfort and peace of mind.
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. This type is also considered a more expensive finding that can add to the overall value of the jewelry piece.
Magnetic Clasp: The popularity of the magnetic clasp has greatly increased in recent years. It is a quick and easy way to secure jewelry while not having to fuss with a tiny clasp, which can be difficult if you have long fingernails, arthritic hands or other mobility challenges. 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. Although this type of clasp is found on both bracelets and necklaces, it is particularly popular on bracelet styles. These types of clasps are often reserved for more expensive jewelry.
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.
Created exclusively by Charles & Colvard, Moissanite is a model of sheer beauty that is fast becoming a shining star in today’s hottest jewelry designs. It is a high-quality unique stone unlike any other.
Moissanite has very high dispersion and displays 2.4 times more fire than diamond (0.044). Its inherent high refractive index gives Moissanite a dazzling sparkle, while its precisely calibrated and carefully hand-cut facet patterns intensify fire and maximize brilliance.
Moissanite is extremely durable. It is harder (more resistant to scratching) than ruby or sapphire – second only to diamond – and it is resistant to breakage.
Larger sizes of near-colorless Moissanite (6.5mm or 1 carat and larger) might appear to have a slight color. A variety of factors, such as dispersion, tint and the type of jewelry setting, can create and affect this unique color appearance. Moissanite aficionados enjoy the slight hue that results in a very natural-looking gemstone.
Moissanite’s high dispersion produces flashes of rich rainbow (spectral) colors. The appearance and degree of these tints are less noticeable when Moissanite is set in jewelry. Jewelry set in gold (yellow, rose or white) and/or set in platinum will affect the face-up appearance of Moissanite.
Nobel Prize-winning chemist Dr. Henri Moissan discovered minute quantities of natural silicon carbide (later named Moissanite in his honor) while analyzing part of Arizona’s Diablo Canyon meteorite crater in 1893. Upon close inspection, he noticed the tiny crystals shimmered with brilliance and dispersion, although they were too limited in quantity and not large enough to use in jewelry.
Almost 100 years after Dr. Moissan's amazing discovery, Charles & Colvard, with the aid of science, developed a way to create Moissanite. Appreciated for its overwhelming brilliance, Moissanite continues to take the jewelry world by storm.
Brilliance: The white light leaving a jewel, traveling upward, which is visible to the eye. Brilliance is sometimes referred to as "sparkle."
Dispersion: Flashes of rainbow colors. Also called "fire."
Hardness: Resistance to scratching. The higher the number, the more resistant.
Luster: The shininess of a jewel.
Toughness: Resistance to breakage.
