Please note that the inner diameter listed is the size of the steel rod that we use to wind that ring size. The finished size will be a tiny bit larger (especially for big/thin rings) because the wire springs back a bit after being wrapped around the rod. And if you want rings with even larger inner diameters than are listed here, please visit the Large Aspect Ratio section of the site.
The rings/ozt numbers in this chart will be closest for sterling silver jump rings. The other metals that we use are slightly less dense than sterling silver. If you’re buying gold filled, brass or copper rings you will get a few more rings in an ounce than you see in the chart.
General Info About White Goldfill
These rings are made with 14/20 gold filled wire. This means that the gold portion is 14 karat (14 parts pure gold, 10 parts other metals), and the gold portion is 1/20th the total weight of the wire. Unlike gold plating, which is often only a few atoms thick, gold fill is much thicker. As a result, the lifetime of gold fill items is measured in decades, not weeks. Additionally, white gold filled jump rings are resistant to tarnishing. To remove dirt and oils, simply soak your chainmaille jewelry in soapy water, then rub briskly with your fingers or palms before rinsing and air drying.
The alloy of 14K gold used for these white goldfill rings is a bit unusual. The “white” of white gold is usually achieved with nickel and silver, but I have a firm commitment to avoiding nickel for all products in the Spiderchain catalog. The other, less common option for white gold is to use palladium to lighten the alloy, and that’s the route I chose. When I look at these rings I think “champagne.” It’s a soft color, not nearly so bright as sterling silver – quietly elegant.

Working with 21 Gauge Jump Rings
Dainty, detailed, and a little bit delicate, 21ga jump rings are a good choice for earrings and necklaces. This wire size can be lovely for bracelets as well, but I recommend sticking with weaves that use smaller aspect ratio sizes to give the finished chain more strength. Birdcage (AKA Byzantine) is a fantastic choice for 21ga bracelets. You’ll probably want to use two pairs of chain-nose pliers for working with 21ga rings, but maybe keep a pair of flat-nose pliers nearby just in case.
