A 1.20mm diameter ball chain necklet in Sterling Silver. Ball chain, also known as bead chain, is made up of small spheres as opposed to traditional links. These spheres are held together with connector bars which can sometimes move freely inside the spheres, allowing greater flexibility. When used in jewellery, thin ball chains can create a delicate but modern look to a design, or larger ball chains can be used to hold military style 'dog tag' ID findings. This ball chain necklet is made up of 1.20mm diameter spheres, and has a total length of 18" (45cm). This chain is fastened with a bolt ring.
