Description
Warm yellow gold and precise diamond-cut facets come together in a cable chain that catches light from every angle. Each square link is machined to a consistent finish, giving the chain a brightness that a smooth-polished surface simply cannot match, all in a profile slender enough to layer or wear alone.
Adjustable length means the chain settles exactly where you want it, whether at the collar or a touch lower. A lobster clasp holds it securely through daily wear, and solid gold construction means the colour runs all the way through, needing nothing more than an occasional polish to look its best.

What affects the price of cable chains?
Metal, width, length and whether the chain is solid drive the price. Karat gold (10K or 14K) costs more than sterling silver or stainless steel, and wider, longer chains use more metal. Diamond-cut finishes and diamond accents also play a part. Use the Price filter on this page to set a budget.
Which cable chain styles are most popular?
Fine gold and sterling silver cable chains lead the list. Diamond-cut 14K yellow gold, flat sterling silver and 10K yellow gold chains in slim widths come first. Stainless steel cable chains and adjustable sterling silver styles follow close behind.
What width of cable chain should I choose?
Choose under 2mm for everyday wear, 3mm and up for presence. Fine widths sit quietly alone or under a pendant. Chains around 4mm to 7mm or wider, including bolder stainless steel options, stand on their own as a statement piece.
Does a diamond-cut cable chain look different from a plain one?
Yes, diamond-cut links sparkle more. Small facets are cut into the surface, so the chain catches light from more angles. Plain and flat cable chains look smoother and softer. Pick diamond-cut for shine, or plain for a quieter everyday look.
How do I pick the right cable chain length?
Match the length to where you want it to fall. Around 16 inches sits close to the collar, 18 inches rests at the collarbone, and 20 to 24 inches hangs lower. Many chains here come in a range of lengths, and adjustable styles let you vary the drop.
Which cable chain metal suits everyday wear?
Solid gold, sterling silver and stainless steel all work for daily wear. Gold stays bright with little upkeep, sterling silver is a budget-friendly classic, and stainless steel suits bolder widths. See sterling silver chains to compare.
