Closure systems: Stability, security and reliability

The closure system is one of the most important elements of the entire piece of jewelry. Stability and a secure hold are, along with reliability, one of the most important factors in the mechanics. We designed our clasps with these basic properties in mind. To guarantee these basic conditions, the quality characteristics are always in the foreground with our clasps.

Clasps, loops and other end pieces

Our assortment of clasps consists on the one hand of loops and on the other hand of decorative closures, the bows. Loops form the connecting link between the carefully selected rhinestone with setting and chain. The jewelry loops form a pendant claw besides a loop or a triangle.

Furthermore, we also offer rings and clips as well as other end pieces for bracelets, necklaces or other jewelry accessories. Whether for attaching drops of jewelry to bracelets or earrings, as end rings for colliers or as clips for cloths, our clasps leave almost no designer wishes unfulfilled.

The secure and creative finish of a piece of jewelry

By means of your jewelry designs and our careful and detailed manufacturing, you can design unique pieces of jewelry. You can use our clasps for necklaces, bracelets, accessories, ear jewelry or other costume jewelry for everyday use or special occasions. Consequently, jewelry designers can use our clasps everywhere as stylish finish.
