What Is a Jump Ring? Types, Sizes, Uses, and How to Choose

A jump ring is one of the smallest parts of a jewelry project, but it can have a big job. These small metal rings are used to connect charms, clasps, chains, pendants, earring parts, and many other jewelry components.

If you are new to jewelry making, learning how to use a jump ring correctly can make your projects much easier. The most important skill is knowing how to open and close one without changing its round shape. You also need to choose the right size and wire thickness for the piece you are making.

What Is a Jump Ring?

A jump ring is a small metal ring used to connect two or more jewelry components. It usually has a small opening where the two ends of the wire meet. This opening allows you to attach a charm, clasp, chain, pendant, or other finding.

Jump rings are available in many sizes, wire gauges, shapes, and metals. Some are made to be opened and closed with pliers, while others are permanently closed.

An open jump ring is useful when you need to attach or remove a jewelry component. A closed jump ring has its ends joined together, often by soldering, so it is not designed to be opened with pliers.

You may find jump rings in round and oval shapes. Round rings are common for everyday jewelry projects, while other shapes can be useful when you need a particular fit or look.

A jump ring can be used to:

• Attach a charm to a bracelet
• Connect a clasp to a chain
• Attach a pendant to a necklace
• Connect sections of jewelry chain
• Add a dangle to an earring
• Attach jewelry findings
• Repair some types of jewelry

Even though jump rings are small, the correct size and wire thickness can make a big difference in how well a finished piece holds together.

How to Use Jump Rings?

Using a jump ring is simple once you learn the correct technique.

For most open jump rings, you will need two pairs of jewelry pliers. Flat nose, chain nose, or similar pliers can work well. Two pliers give you better control over the ring and help you make small adjustments.

Here is the basic process:

1. Hold the jump ring with one pair of pliers on one side of the opening.
2. Hold the other side with your second pair of pliers.
3. Twist the two sides in opposite directions to create an opening.
4. Slide the charm, chain, clasp, or other component onto the ring.
5. Twist the two sides back together.
6. Check the join carefully to make sure there is no noticeable gap.

The important part is the direction in which you open the ring. Do not pull the two ends straight away from each other. Twist the sides instead. This helps the ring keep its original round shape. Jewelry making guides commonly recommend this method because pulling the ring apart can make it harder to close neatly.

Take your time when working with small rings. A good pair of pliers can give you much more control, especially when working with smaller jump rings.

How to Open Jump Rings?

Opening a jump ring correctly is one of the first techniques a new jewelry maker should learn.

You will usually need two pairs of pliers.

Step 1: Hold the ring

Hold one side of the jump ring with one pair of pliers. Hold the other side with your second pair.

Position the opening between the two pliers.

Step 2: Twist the ring

Move one pair of pliers toward you while moving the other pair away from you.

This creates a small opening without pulling the entire ring out of shape.

Step 3: Attach your component

Once there is enough space, slide the chain, charm, clasp, or other component onto the jump ring.

You normally only need to open the ring enough to fit the component through it.

Step 4: Close the ring

Reverse the twisting movement and bring the two ends back together.

The key thing to remember is:

Twist a jump ring open. Do not pull it straight apart.

This technique helps keep the ring closer to its original circular shape.

Opening a ring too far can also make it harder to close neatly, so use the smallest opening that lets you add your jewelry component.

How to Close a Jump Ring?

After adding your jewelry component, the next step is to close the jump ring.

Hold each side of the opening with your two pairs of pliers. Slowly twist the sides back toward their original position.

Look closely at the two ends.

They should meet as evenly as possible. If there is a small gap, make tiny adjustments with your pliers until the ends line up.

Do not squeeze the ring aggressively. Small movements give you better control.

A properly closed jump ring should have the ends sitting together without an obvious opening. Jewelry making instructions also recommend checking the join visually after closing because a gap can allow a component to slip out.

Before finishing your jewelry piece, gently test the connection. If the ring moves apart easily or you can see a clear gap, adjust it again.

Types of Jump Rings?

There are several types of jump rings, and each one can be useful for a different project.

1: Open Jump Rings

Open jump rings have a small opening and can be opened with pliers. They are commonly used for attaching charms, clasps, chains, and other jewelry components.

2: Closed Jump Rings

Closed jump rings have no usable opening. They are often soldered or otherwise permanently joined.

They can be useful where you want a permanent connection.

3: Split Rings

Split rings have a construction similar to a tiny key ring, with overlapping layers of wire. They can provide a secure connection for some jewelry and accessory projects.

4: Oval Jump Rings

Oval jump rings have an elongated shape rather than a perfect circle. Their shape can be useful when connecting certain jewelry components.

5: Heavy Jump Rings

Thicker jump rings are useful for projects that need more strength. The correct choice depends on the weight of the jewelry and how much movement or pulling the connection will experience.

What Size Jump Ring Should You Use?

Jump ring size is usually discussed in millimeters, while wire thickness is often described by gauge.

The outside diameter tells you the overall width of the ring. The inside diameter tells you how much usable space there is inside the ring.

Wire gauge describes the thickness of the wire. With many common gauge systems, a higher gauge number means thinner wire. For example, A Girl's Gems notes that its 20 gauge jump rings are thicker than its 22 or 24 gauge options.

There is no single jump ring size that works for every jewelry project.

A small lightweight charm may work well with a small ring. A bracelet with several heavier charms may need a thicker ring.

Jump Ring Size and Gauge Chart

The measurements below are general guidelines rather than universal sizing rules. Actual dimensions can vary by manufacturer, metal, and product.

Jump Ring Size	Approx. Wire Thickness	Common Uses	Strength	Beginner Notes
2–3 mm	Thin	Small beads, delicate jewelry	Light	Good for small lightweight parts
3–4 mm	Medium	Charms, earrings, small bracelets	Medium	Useful for many small projects
4–5 mm	Medium	Bracelets, necklaces, charms	Medium to good	A common size range
5–6 mm	Medium to thick	Bracelets, clasps, larger charms	Good	Useful when more space is needed
6–8 mm	Thick	Larger charms, chain, heavier designs	Good to high	Check that the larger ring suits the design

Always check the actual product specifications before buying because the same diameter can be available in different wire gauges.

How Strong are Jump Rings?

The strength of a jump ring depends on more than its diameter.

Wire thickness is one of the main factors. A thicker ring generally provides more resistance to bending than a thinner ring made from the same type of metal.

The metal itself also matters. The shape and construction of the ring can affect how it behaves during use.

Other factors include:

• Ring diameter
• Wire gauge
• Metal type
• Whether the ring is soldered closed
• Weight of the jewelry
• Size and type of clasp
• How much movement the jewelry receives
• How well the ring has been closed

For a lightweight necklace charm, a thin jump ring may be enough. For a bracelet with several heavier charms, a stronger ring may be a better choice.

Do not choose a jump ring based on diameter alone. Consider both its size and wire thickness.

How to Make Jump Rings?

You can make jump rings yourself from jewelry wire.

You will need jewelry wire, a round mandrel or another suitable cylindrical tool, cutters, and pliers. For clean results, the cutting tool should be suitable for the type and thickness of wire you are using.

Start by wrapping the wire around the mandrel. Keep the coils close together so they form a consistent spiral.

After creating the coil, cut through the wire to separate individual rings.

The size of the mandrel affects the diameter of the finished rings. The wire thickness affects the gauge and strength.

After cutting the rings, check the ends. Rough or uneven cuts can make a ring difficult to close and may create a sharp edge.

Making your own jump rings can be useful when you need a particular wire type, size, or finish. However, ready-made jump rings can save time and give you more consistent sizes when making several pieces of jewelry.

How to Solder Jump Rings?

Soldering a jump ring means joining its ends permanently with solder and heat.

This can be useful when you want a connection that is not meant to be opened during normal use. Closed soldered rings can be used in some bracelet, necklace, chain, and other jewelry designs.

The basic process involves:

1. Select a suitable jump ring and soldering setup.
2. Close the ring so the ends meet cleanly.
3. Clean the metal as required for your soldering method.
4. Apply the appropriate solder and heat.
5. Allow the connection to cool.
6. Clean and inspect the finished joint.

Soldering requires proper jewelry making equipment and safe working conditions. Work in a suitable area with good ventilation and use the protective equipment recommended for your tools and materials.

If you are new to jewelry soldering, practice on scrap metal before working on a finished piece.

For projects where the ring needs to remain removable, use an open jump ring instead of soldering it closed.

How to Choose Jump Rings for Bracelet Making?

Bracelets move constantly while they are being worn. They can also experience pulling when the wearer puts them on, takes them off, or catches them on clothing.

For this reason, choosing a suitable jump ring matters.

Start by looking at the weight of the bracelet components.

If your bracelet has one small, lightweight charm, you may not need a very large ring.

If it has several charms, a heavier clasp, or larger metal components, consider a thicker jump ring.

You should also check:

1: Wire Gauge

A thicker wire can provide more resistance to bending. Check the gauge rather than assuming that a larger diameter automatically means a stronger ring.

2: Inner Diameter

The inside opening needs to be large enough for the component you are attaching.

A ring can have a large outside diameter but a relatively small opening if the wire is thick.

3: Metal

Choose a metal that works with the rest of your bracelet.

For example, you may want the jump ring color and metal to match the chain, clasp, or other findings.

4: Bracelet Design

A delicate bracelet may look better with a smaller ring. A chunky bracelet may need a larger and thicker ring.

5: Clasp

Check the connection point on your clasp before choosing the ring. The jump ring needs to fit through the clasp loop without being so large that it looks out of place.

A Girl's Gems offers jump rings in several sizes and gauges, including 14K gold filled and 925 sterling silver options, as well as stainless steel and other findings. Its collection includes options such as 20, 22, 24, 19, 18, and 16 gauge products in different sizes.

Jump Rings for Different Jewelry 

Different jewelry projects may call for different jump ring sizes and gauges.

1: Bracelets: Choose a size and gauge based on the bracelet's weight, clasp, charms, and amount of movement.

2: Necklaces: Small rings can work for lightweight pendants, while larger pendants may need thicker rings.

3: Earrings: Lightweight earrings often use small jump rings, but the ring still needs to fit securely through the finding.

4: Charms: Choose a ring that fits through the charm loop and is strong enough for its weight.

5: Keychains: These usually need stronger rings because they receive more pulling and movement than delicate jewelry.

6: Clasps: Check the size of the clasp loop before choosing your jump ring.

The best jump ring is the one that fits the component and provides enough strength for the finished item.

Frequently Asked Questions about Jump Rings

What is a jump ring used for?

A jump ring is used to connect jewelry components. You can use one to attach charms, clasps, pendants, chains, beads, and other findings. Open jump rings can be opened with pliers, allowing you to add or remove components.

What size jump ring should I use for a bracelet?

The right size depends on the bracelet design, component size, weight, and wire gauge. Small lightweight bracelets may use smaller rings, while heavier bracelets or designs with several charms may need thicker rings. Check both the diameter and gauge before choosing.

How do you open a jump ring without damaging it?

Use two pairs of jewelry pliers and twist the sides in opposite directions. Do not pull the ends directly apart. Twisting helps the ring keep its round shape and makes it easier to close correctly afterward.

Can you solder a jump ring closed?

Yes. A suitable jump ring can be soldered closed when you want a permanent connection. Soldering requires the correct tools, materials, ventilation, and safety equipment. It is best to practice on scrap metal if you are new to soldering.

What is the difference between an open and closed jump ring?

An open jump ring has a small gap that allows you to attach jewelry components with pliers. A closed jump ring has its ends permanently joined and is not designed to be opened in the same way.

Are thicker jump rings stronger?

A thicker wire generally provides more resistance to bending than a thinner wire made from the same type of metal, but strength also depends on the metal, ring size, construction, and how the ring is used.

How do you keep a jump ring from opening?

Use the correct gauge for the jewelry project and close the ring carefully so the ends meet properly. For connections that need to remain permanently closed, a soldered ring may be appropriate.

Conclusion

A jump ring might be small, but it holds your jewelry together, literally. Once you understand the right way to open, close, make, and solder one, you will run into far fewer broken bracelets or missing charms.

Start simple. Pick a gauge, practice the twist and close motion on a spare ring, and build from there. With a little practice, working with jump rings will feel just as natural as stringing a bead.

Jump rings are simple jewelry findings, but using the correct technique makes a noticeable difference.

Remember these basic points:

• Twist a jump ring open instead of pulling it apart.
• Use two pairs of pliers when possible.
• Open the ring only as much as you need.
• Make sure the ends meet when you close it.
• Choose the size based on the component you are attaching.
• Check the wire gauge as well as the diameter.
• Use thicker or permanently closed rings when the project requires more security.
• Match the metal and finish to the rest of your jewelry.

Once you are comfortable opening and closing jump rings, they become one of the most useful parts of a jewelry making kit. If you need different sizes and materials for your next project, you can browse the jump ring collection at A Girl's Gems.
