Each chain differs in the kind of links: the beaded chain, for example, is composed of spheres instead of open links. These tiny spheres are attached at regular intervals along the length of the chain by connecting bars. This type of jewellery chain generally requires a snap clasp.
The forzatina chain is the most common type and takes its name from the large chains used on ships to tie together convicts destined for penal colonies. It is made up of individual oval links that intertwine in a uniform pattern, with each link set at ninety degrees to the next. Each section of a forzatina chain, in gold or silver, is identical to the next, giving it a simple yet classic appearance.
The curb chain is a variation of the previous one, in which the links are twisted and diamond-cut so that they lie flat along the surface. This shape of gold or silver chain has a wide variety of widths, ranging from a few millimetres up to several centimetres.
The rolò chain is composed of alternating round links, welded to give a more comfortable feel and superior strength. These links are more wide than thick, the wire has a semi-round cross-section and the inner side of the link is flat, which differentiates them from forzatina chains.
The Venetian chain, on the other hand, is popular for its geometric simplicity. It is made of wire that is flattened and bent to form cubic links that provide a robust but classically smooth, shiny, and uniform appearance. It is the rhodium-plated 925 silver or gold chain most commonly used to wear pendants, also made in silver or gold, which are usually given as gifts for Baptism or Holy Communion.
