50 x Jumpring in stainless steel 1.2x5mm

What is a jump ring?

A jump ring is a small metal ring (usually round, sometimes oval) with a small cut or slit that allows it to open and close. They’re one of the most basic and essential findings in jewelry — like the screws and nails of the jewelry world.

What are jump rings used for?

• Connecting components: e.g. pendants to chains, clasps to necklaces, charms to bracelets.
• Extending: joining pieces together to add length.
• Finishing ends: attaching to cord ends, tags, or dangles.
• Creating chainmaille designs or decorative links.

Why stainless steel jump rings?

• Made from 304 or 316L stainless steel, which is: Rust-resistant and corrosion-resistant
• Hypoallergenic (ideal for people with sensitive skin)
• Won’t tarnish or lose color
• Stronger and more durable than plated brass or copper
• Keep their shape better than softer metals: harder to bend out of shape accidentally.

Sizes & gauges

Jump rings come in many diameters (from about 3 mm to over 15 mm) and different wire thicknesses (gauges):

• Inner diameter: the space inside the ring
• Outer diameter: the full width including the wire
• Wire gauge: how thick the wire itself is (thicker = stronger, but harder to open)

Common jewelry sizes:

• 4 mm / 5 mm / 6 mm for small charms and fine chains
• 7–9 mm for medium pendants and bigger clasps
• Thicker gauges (e.g. 1.0 mm or 18–20 gauge) are stronger for heavy pieces

➿ Types of jump rings

1️⃣ Open jump rings:

• Have a single split; you twist to open and close.
• Standard for most jewelry connections.

2️⃣ Closed jump rings:

• Fully soldered shut; cannot be opened.
• Used where strength is critical (e.g., to prevent a clasp from pulling open).

3️⃣ Double jump rings:

• Like two rings wrapped together (like a mini keyring).
• Extra security; makes it harder for things to slip out.

✨ Finish & style

• Natural steel silver-gray shine (often mirror polished)
• Can also find gold-tone, rose gold, or black IP plated stainless steel jump rings
• Matte brushed finishes are rarer but possible

Tips for using stainless steel jump rings

• Use two pairs of pliers to open/close — always twist, don’t pull apart sideways.
• Stainless steel is tougher than brass or copper — it takes a bit more effort to bend.
• For critical connections (like a pendant on a heavy chain), consider a soldered or closed ring so it can't open accidentally.

✅ Why people love them

• Strong, reliable, and keep jewelry looking new for years.
• Affordable but look professional.
• Pair well with stainless steel chains, clasps, and other findings for a cohesive look.
