Necklace buttons commonly include W button, S button, spring button, hidden button, fishtail button and so on. Among them, W-buckle and S-buckle are common on metal necklaces with good ductility such as gold and platinum, while spring buckle is common on some slender and delicate necklaces, hidden buckle is common on many big-name jewelry necklaces, and fishtail buckle is mostly used on pearl necklaces.

W-buckle W-buckle is a kind of necklace buckle. W button is also called "M button". This kind of buckle is mainly opened and closed by hand. Metal necklaces with good ductility, such as gold and platinum, often use this clasp because it is not easy to break and has good load bearing.

S-buckle S-buckle is also a common necklace buckle. Similar to W-buckle, this buckle needs to be broken by hand to wear, and it is mainly used for malleable metal ornaments such as gold and platinum, but the difference is that one side of this buckle is welded firmly and the other side can be broken off, effectively preventing the necklace from slipping.

Spring buckle Spring buckle is a common mechanical buckle in necklaces. This kind of buckle controls the opening and closing of the buckle through the spring-loaded mechanism, and is used for most slender and delicate necklaces.

The hidden button is named because the shape of the button cannot be seen. This buckle is fixed by the spring clamping into the groove, and its shape can be round or square. Many big-name and high-grade jewelry can often see this hidden clasp, because this clasp will not affect the overall beauty of the necklace.

Fishbone buckle In addition, fishbone buckle is also a kind of necklace buckle, which is usually used for pearl necklaces. With this buckle, you can wear a necklace just by hanging a small hook on the fishhook buckle, but the disadvantage of this buckle is that it can't bear overweight items.
