Jump rings

Jump rings are (usually metal) rings used to make chains, jewelry and chainmaille. They are made by wrapping wire round a mandrel to make a coil and then cutting the coil with wire cutters to make individual rings. The rings can be assembled one by one into chains, earrings, objects such as bowls or ornaments, and chain mail clothing.

The making of items from jump rings is called chain maille ("maille" is French for "mesh").

Jump rings can be described by the following qualities :

Gauge : The thickness of the wire the ring is made from. Usually measured according to American Wire Gauge standards or in millimetres, but SWG (Standard Wire Gauge) may be used.
Inner diameter: Approximately the same as the outer diameter of the mandrel used to create the rings, but the exact inner diameter will depend on the degree to which the wire springs as it comes off the mandrel.
Kerf width : The gap between the ends of the jump ring created by the cutting process
Cut type : Saw cut or pinched. The former produces a clean uniform cut whereas the latter is pinched and looks less attractive.
Outer diameter: The outer diameter of the ring, this is the same as (twice the gauge + the inner diameter).
Colour For example, anodised aluminium rings come in many colours.
Material: The common materials are gold (or plated gold), silver (or plated silver), aluminium, brass, stainless steel, copper, niobium, and titanium.
