What is a split ring in jewellery?

Definition
A split ring in jewellery making is a small finding made from a tightly wound double loop of wire, essentially a miniature key ring, used to attach charms, pendants or clasps to a chain or bracelet. Because the wire is doubled back on itself, pieces threaded onto a split ring cannot slide off accidentally the way they can from a simple open jump ring. They are fiddly to open without the right pliers but very secure, which makes them useful anywhere you need a reliable, permanent-seeming connection.
Frequently asked questions
- What is the difference between a split ring and a jump ring?
- A jump ring is a single open circle of wire with a cut gap that you pry open and close. A split ring is a doubled loop of wire with no gap, like a key ring, so the connection is far more secure. Jump rings can open accidentally under tension; split rings generally cannot.
- Do I need special pliers to open a split ring?
- Split ring pliers have a small hook or notch on one jaw that catches the coil and pries it open, making the job much easier on your fingers and nails. You can manage without them but it is uncomfortable work for anything other than the occasional ring.
- What size split ring should I use for a charm bracelet?
- For most charm bracelets a split ring between 5mm and 8mm works well, depending on the thickness of the bracelet wire or links. Match the ring diameter to the finding you are attaching it to, and make sure the wire gauge is heavy enough for the weight of the charm.
