9ct Yellow Gold Box Chain 0.60mm 50cm

A box chain is formed from square-section links that close into a continuous row of cubes. The squared profile gives four flat faces along the chain, so light is returned in clean lines rather than scattered.

This piece is 9ct yellow gold, 0.6 mm across the nominal width and 50 cm long, weighing approximately 1.166 g — solid throughout, not hollow-filled. The articulation is tight and the drape is deliberately low, which keeps a pendant hanging dead centre instead of drifting. It is the usual choice where a pendant needs to sit still.

Will this suit me?

• Where it sits: At 50 cm it sits just below the collarbone and clears a crew neckline, giving a pendant room to hang free of fabric. It is also the usual starting length for men.
• How it looks: At 0.6 mm this is a fine chain: a thin, bright line that reads as delicate on its own and lets a small pendant take the attention. It weighs about 1.2 g. The square links give a sleek, smooth line that catches the light evenly.
• With a pendant: Suits a light pendant or charm, such as a small solitaire. For anything heavier, a chain of 1.3 mm or more is the safer match. A pendant slides freely along the smooth, square links.
• Everyday wear: 9ct is the harder alloy and stands up well to daily wear. It is solid throughout, so a jeweller can repair or shorten it. Fine chains are the most delicate kind: take it off to sleep, swim and train, and store it hanging or laid flat to avoid knots.
• 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: 40 cm, 45 cm, 60 cm. Metals: 18ct white gold, 18ct yellow gold, 9ct white gold. Widths: 0.52 mm, 0.8 mm.

9ct yellow gold is 375 parts per thousand fine gold. The higher alloy content makes it hard and more scratch-resistant than 18ct, which is why it's always been the popular choice for everyday wear.

Servicing. The closed box profile is straightforward to solder, though the join must be cleaned back flush to keep the square line unbroken.

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