Necklace Jump Ring: 4 Essential Tips Every Jewelry Maker Should Know

When it comes to making necklaces, jump rings are small but mighty components. They connect chains, attach clasps, and secure pendants — meaning your entire piece depends on them doing their job well. If you're just getting started with jewelry making or want to refine your techniques, here are 4 essential things you need to know about necklace jump ring:

1. Choose the Right Size

For most necklaces, jump rings between 4mm and 7mm in diameter are ideal. The size you choose depends on your chain thickness and the component you're attaching (like a clasp or charm).

• 4–5mm: Great for delicate chains

• 6–7mm: Suitable for medium to heavy necklaces

✔️ Tip: The jump ring should be large enough to accommodate both the chain and clasp, but not so big that it looks bulky.

2. Pick the Proper Gauge

The gauge refers to the thickness of the wire. For necklaces, 18 gauge is a reliable all-purpose choice.

• 20–22 gauge: Thin and flexible, but may open easily

• 18 gauge: Strong and secure for everyday wear

• 16 gauge: Extra sturdy, best for heavy pendants or chunky chains

?️ Use two pairs of pliers to twist jump rings open — never pull them apart.

3. Use the Right Type: Open vs. Closed

• Open jump rings can be twisted open and closed and are easy to use for most necklace projects.

• Closed jump rings are soldered shut and offer added security for clasps or pendant drops.

? Pro tip: Use a closed jump ring at the clasp end to prevent accidental openings.

4. Match the Metal

Always use jump rings that match your necklace’s metal in both color and material. Mixing metals can affect appearance and durability.

• Sterling silver chain → sterling silver jump ring

• Gold-filled chain → gold-filled jump ring

• Stainless steel → stainless steel

? Matching metals creates a polished, professional look and avoids tarnishing issues.

Final Thought

A strong, well-matched jump ring keeps your necklace both stylish and secure. Pay attention to size, gauge, type, and material — your necklace (and your customers!) will thank you.
