There are many different types of clasps for necklaces and bracelets that must be secured around the person wearing the piece of jewelry. A bolt ring clasp is the most common type of clasp you’ll find on Western jewelry that isn’t of a heavyweight. This clasp, which is also called a spring clasp, consists of a spring that one opens and closes when one uses their fingers or fingernails to press the clasp back to open it. Letting go of the clasp after the necklace or bracelet has been secured around the wearer’s neck or wrist secures it onto a link to the jewelry piece. Bolt ring clasps are popular because they are easy to use, functional, and affordable. The sizes of bolt ring clasps vary greatly. You can find these types of clasps ranging from 5mm to 22mm. Additionally, if wear and tear causes a bolt ring clasp to break, they are fairly affordable and easy to fix, thus allowing the piece of jewelry to be worn and enjoyed for years to come.
