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 Rose 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, 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.
14K gold is especially well suited to colored alloys. Pure gold makes up 14 parts out of 24, so the gold color is nice and rich, and with 10 parts out of 24 for other metals (with other colors) that rich gold can be “tweaked” quite a bit. Rose 14K gold is a great example of this. The rich red of copper combines with gold to make a beautiful rosy-warm golden color that looks amazing when combined with sterling silver (or green niobium!)

Working with 12 Gauge Jump Rings
Chainmaille jewelry made with 12 ga jump rings will be very (very!) substantial. These sizes also work well as big, bold accent rings in striking modern designs. I recommend using two pairs of the extra-wide duckbill pliers to give the best control of these heavy gauge rings.
