What Are Jump Rings Used For in Jewelry Making? Types, Sizes & Uses

A jump ring is a small jewelry finding that helps connect different parts of a piece. It can attach a clasp to a chain, connect a charm or pendant, or link an earring drop to an ear wire. Although it is small, it plays an important role in keeping a finished piece connected and functional.

Choosing a jump ring is not just about finding one that fits. Its gauge, material, shape, and construction can affect how well it works for a particular design.

In this guide, we’ll look at the different ways jump rings are used in jewelry making, the types available, how to choose the right one for your project, and how to open and close it properly.

What Is a Jump Ring?

A jump ring is a small metal ring made from wire, with a cut that creates an opening. The opening allows the ring to be twisted apart, threaded onto a jewelry component, and closed again with pliers.

Jump rings are available in different sizes, gauges, shapes, and constructions, and are one of many jewelry findings used in jewelry making. Common options include open jump rings, closed or soldered rings, and split rings.

What Are Jump Rings Used For?

Attaching clasps to chains

Jump rings are commonly used to connect clasps such as lobster clasps, spring rings, and toggle bars to a chain. They create a small connecting point between the clasp and the chain, allowing the clasp to move freely without putting all the movement on the chain's end link.

Adding charms and pendants

A gold jump ring for a necklace can attach a charm, pendant, or gemstone drop to a necklace or bracelet. It also makes the component easier to remove or replace when you want to change the design.

Making dangle earrings

Jump rings can connect ear wires to pendants, chain sections, bead clusters, and other earring components. Using one or more rings allows these pieces to hang and move freely.

Joining multi-part and layered designs

Layered necklaces, tiered bracelets, and multi-strand designs often use jump rings to connect separate sections. They can bring several components together while keeping the overall design flexible.

Repairing jewelry

Jump rings can also be useful for simple jewelry repairs, such as replacing a lost charm connection or reconnecting a clasp. In some cases, replacing the damaged ring is all that is needed to restore the connection.

Chainmaille and woven designs

Jump rings are also used as the main building blocks in chainmaille jewelry. Hundreds or even thousands of rings can be linked into patterns such as European 4-in-1 and Byzantine weaves, turning the jump ring itself into part of the finished design.

What Types of Jump Rings Are Available?

Jump rings come in different constructions and shapes, and each has a slightly different use.

By construction

By shape

• Round: The most common shape and a versatile choice for everyday jewelry connections.
• Oval: Provides a longer connection point and can work well when the position or movement of the connected components matters.
• Twisted or decorative: Adds visual detail and can be used as part of the design, particularly in chainmaille and other decorative jewelry.

How Do You Choose the Right Jump Ring?

Choosing a jump ring depends on what you are connecting and how the finished piece will be used. The diameter, wire gauge, and material all play a role.

Diameter

The ring's inner diameter needs to be large enough to fit the chain link, charm loop, or clasp attachment point, with enough room for the components to move freely. A fine cable chain and small charm loop may need a smaller ring, while a heavier pendant or larger clasp may need more space. Test-fitting the ring with the actual components is often more useful than relying on a standard size chart.

Wire gauge

A thicker wire provides greater resistance to bending and pulling open, while a thinner wire gives a lighter look. Heavier charms and clasps generally need a thicker gauge, especially when the connection will be exposed to regular movement or tension.

Material

Solid gold, including 18K gold jump rings, and sterling silver are commonly used for durable jewelry and can provide a reliable connection when the ring is properly sized and gauged. Gold-filled and gold-plated rings offer a gold appearance at a lower cost, although the surface layer can wear with repeated handling. Uncoated brass and copper are more budget-friendly options, but they can tarnish more quickly and may be better suited to designs where their natural finish is part of the look.

How Do You Open and Close a Jump Ring?

A jump ring should be opened by twisting the ends apart, not by pulling them sideways. Pulling the ring open can distort its shape and make it harder to close properly.

To open it: Hold the ring with a pair of pliers on each side of the opening. Twist one side toward you and the other away from you, keeping the ends in different planes. Open it only as much as needed to add the jewelry components.

To close it: Use the same twisting motion in reverse until the two ends meet. Check the seam with your fingertip. If you can feel a gap or a misalignment, adjust the ring gently with the pliers until the ends sit flush and the ring returns to its original shape.

Jump Ring vs. Split Ring: What's the Difference?

A jump ring has a single opening and can be twisted open with pliers. A split ring is a double-coiled loop, similar to a miniature keyring, and is designed to keep components from slipping off easily. Instead of opening it with pliers, components are threaded onto the split ring by sliding them along the coil.

Jump rings are quicker to use and provide a clean, low-profile connection for most jewelry projects. Split rings take more time to attach but can offer extra security against accidental opening, making them useful for pieces that experience regular movement or wear.

As a general rule, jump rings work well for everyday jewelry connections, while split rings can be a better choice when keeping a component securely attached is a higher priority.

Common Jump Ring Mistakes to Avoid

• Pulling the ring open sideways: This can distort the ring and make it difficult to close neatly. Twist the ends apart instead.
• Leaving the ends misaligned: A gap or uneven seam can weaken the connection and may catch on fabric or hair.
• Using a gauge that is too fine: A thin ring may bend or stretch when used with a heavier charm, clasp, or other component.
• Choosing a ring that is too large: An oversized ring can look out of proportion and allow connected components to move more than intended.
• Reusing a ring too many times: Repeated opening and closing can work-harden or fatigue the metal around the opening, so replace a ring if it no longer closes cleanly.

A Small Component Worth Getting Right

A well-matched jump ring can help create a secure connection while complementing the proportions and finish of the piece.
