Silver extension chains are suitable for making jewellery that needs a partially variable length. Working with extension chains is very easy and even beginners can handle it. Using a connector ring, you attach an extension component to one segment of a clasp and so create a counterpart of a variable length. All extension chains are made from silver with fineness of 925/1000 and we also offer them in gold-plated versions of 24k gold or 18k rose gold.
