18ct White Gold Diamond-Cut Curb Chain 2.16mm 40cm

A curb chain is made by twisting each link ninety degrees and compressing it so that it lies flush against its neighbour. The faces are then diamond-cut — machine-faceted back to a bright mirror surface — which is what gives the chain its flash along the length.

This piece is 18ct white gold, 2.16 mm across the nominal width and 40 cm long, weighing approximately 6.92 g — solid throughout, not hollow-filled, rhodium plated. Because the links interlock face to face rather than edge to edge, a curb chain feels denser and more solid in the hand than an open-link chain of the same nominal width, and it lies flat against the skin.

Will this suit me?

• Where it sits: At 40 cm it sits high, at the base of the throat, just above the collarbone. It is the shortest standard length and works best alone or as the top layer. On a larger neck it fits closely, so if it's for a man, 50 cm is the usual starting point.
• How it looks: At 2.16 mm it has real presence: enough to be worn on its own without looking heavy. It weighs about 6.9 g. The links lie flat against the skin, and the diamond-cut faces add brightness.
• With a pendant: Carries heavier pendants, including those with a wide bail.
• Everyday wear: 18ct is softer than 9ct and richer in colour; it wears well day to day with a little care. The bright white finish is rhodium plating, which wears with daily contact and can be renewed by a jeweller. It is solid throughout, so a jeweller can repair or shorten it.
• Finding your length: Measure a chain you already own from end to end, clasp included, or run a piece of string around your neck to where you'd like it to sit. Our sizing guide has more help.
• Other options: Lengths: 45 cm, 50 cm, 60 cm. Metals: 18ct yellow gold, 9ct white gold, 9ct yellow gold. Widths: 1.4 mm, 2.8 mm.

18ct white gold is 750 parts per thousand fine gold in a white alloy, finished with rhodium plating. The plating is a wearing surface and is renewable; beneath it the alloy carries a faint warm cast, which is normal for white gold.

Servicing. Solid curb links take a solder join well; the faceted faces should be re-cut or re-polished after any repair so the join does not read as a dull spot.

Weights are supplier figures and are approximate; small variation between individual pieces is normal in chain manufacture.
