Argentium Jump Rings
4mm diameter rings = 0.8mm diameter wire
5mm diameter rings = 1mm diameter wire
6mm diameter rings = 1mm diameter wire
Made in Argentium 935 Silver, these jump rings are tarnish and firestain resistant, with hypoallergenic properties and a bright-white colour. If you are soldering or fusing them, a low-temperature heat-treatment can increase hardness and durability.
