Jump Ring Types: Which Should You Use?

What Are Jump Rings?

Jump rings are small metal rings used to connect components in jewelry making—attaching a clasp to a chain, connecting a pendant to a bail, linking charms to earrings, or building chainmaille patterns. They are among the most fundamental jewelry-making components, yet the differences between types are significant and can determine whether a piece of jewelry lasts a lifetime or falls apart within months.

Jump Ring Metals and Alloys

Jump rings come in the same range of metals as finished jewelry: sterling silver, fine silver, 14K or 18K gold (in various colors), gold-filled, brass, copper, stainless steel, and niobium. The metal choice affects conductivity, hypoallergenic properties, hardness, and cost. For finished jewelry that will be worn, always match or exceed the quality of the other components.

Jump Ring Sizes and Gauges

Jump rings are specified by two dimensions: inner diameter (ID) and wire gauge (thickness). A ring described as 4mm 20ga has a 4mm inner diameter and uses 20-gauge wire. Thicker wire (lower gauge number) creates stronger rings; thinner wire (higher gauge) creates more delicate-looking rings. The ring diameter must match the component it will connect.

Closed vs Open Jump Rings

Open jump rings have a small gap that allows them to be threaded through other components before being closed with pliers. Closed jump rings are soldered shut in a circle and are used when a permanent, secure connection is required. For structural connections—attaching a clasp to a chain—always use closed, soldered jump rings.

Wire Shape: Round vs Half-Round vs Square

Round wire jump rings are the most common and work for most applications. Half-round wire jump rings have one flat side and one round side—when the flat side is soldered, they create a smooth, flush connection ideal for visible chain connections. Square wire jump rings are used in chainmaille and create a distinctive geometric aesthetic.

Frequently Asked Questions

How do I close a jump ring without distortion?

Use two pairs of chain-nose or flat-nose pliers. Hold one side in each hand and bring them together gently—pushing rather than pulling. Never twist or pull apart, as this will distort the round shape.

Should I solder jump rings?

For any structural connection—anything that will bear weight or experience movement—soldered jump rings are strongly recommended. An unsoldered jump ring can work itself open over time.

What gauge jump ring should I use?

For most jewelry, 20-22 gauge jump rings are appropriate for smaller connections (clasps, earrings). For structural connections like heavier chains or larger pendants, use 18-20 gauge.

Why do my jump rings keep breaking?

If jump rings break during construction, the wire may be work-hardened from over-handling. Use fresh jump rings. If they break after wearing, the ring may have been undersized for the load.

Can jump rings be used to resize a ring?

Adding a jump ring to a chain necklace (to make it shorter) or using a jump ring as a connector for an extender chain is a legitimate resizing technique. Never try to add a jump ring directly to a finger ring band to change its size.
