Which pendant bail suits a thick chain and which suits a thin one?

ZKZ Editorial TeamMain answer · Product & gemmology desk

The bail should let the chain pass through freely without being so wide that the pendant slides, tilts or looks oversized. A thin chain suits a small or medium bail, and a thick chain needs a large opening. Check the inner size of the bail in millimetres against the chain width, clasp and any links, before buying.

How the two interact

• Too small a bail. The chain will not fit, or it fits but the clasp or a link jams. Forcing it can bend the bail or scratch the chain.
• Too large a bail. The pendant moves and twists, and can sit sideways.
• A good fit. The chain moves smoothly and the pendant hangs straight.

Measuring

1. Ask the seller for the inside width and height of the bail, not only the outside size.
2. Measure the thickest part of your chain, including the clasp. The chain has to pass over the clasp if you thread it on.
3. Allow a little space, so the chain does not rub the bail tightly on each side.

Bail styles

• Fixed bail. Soldered to the pendant. Sturdy, but its size is fixed.
• Hinged or open bail. Can be opened so that a chain with a large clasp or a decorative link fits. It is more flexible, but a hinge is a point of wear.
• Tube or slide bail. A tube that slides along a chain, often used with flat or round chains.
• Jump ring. A small ring that joins the pendant and the bail. It lets the pendant swing and turn.

Choosing by chain

Our advice A fine cable or box chain suits a small, neat bail. A thick curb, rope or snake chain needs a wide bail or a tube. If you want to swap chains often, choose a larger bail and check the fit with each.

Care

Fact GIA says fine jewelry should be checked every six months. For a pendant, check the bail and the jump ring for wear, thinning or a gap.

Our advice A bail that is rubbed by a heavy chain wears faster, and a worn bail can break and lose the pendant. If you see a bright worn patch or a thin spot, have it checked.

It depends A pendant that is meant to sit on a chain for life can have a bail made to the chain. A custom bail is an option from a jeweler.

Uncertain We cannot match exact sizes without the pieces, so measure both before you buy.
