16 Comon Necklace Clasp Types

The necklace clasp is a part of the exquisite necklace, bearing the two primary responsibilities of fixing the chain and perfecting the overall effect of the necklace, which is an indispensable part of the necklace. A necklace clasp hidden in the subtle is not often concerned, but it has excellent knowledge. Let’s understand!



W-clasp, also known as M-clasp. We know its name from its shape. W-clasp most often appears in plain, gold, and platinum jewelry. Because gold and platinum have relatively high ductility, the metal can bear repeated bending without breaking, so such a clasp is the best. The W-clasp is usually welded on one side to prevent the necklace from falling off, and the other side is used to open and close. Its opening and closing are mainly broken by hand, which should be bent many times each time it is taken and worn, but if it is broken too hard, it will cause the clasp to break. Repair if you find any signs of damage.



S-clasp is often used on bracelets. When used, the S-clasp must be broken off before it can be worn, so it is also used for metals with excellent ductility, such as gold and platinum. The S-clasp is not a clasp with two sides open; the clasp is usually welded to one side to prevent the necklace from falling off, and the other is used to open and close.
