Best 10 karat gold necklaces and chains

Start here: the 10K solid yellow gold rope chain, 4 mm, 26 inches. A rope is the most forgiving chain to own — the twist hides scratches, it holds up to daily wear, and at 4 mm it reads substantial without being heavy. It's the one I'd buy first.

Who the others suit:

• Miami Cuban link (3–10 mm, 20–30 in): pick this if you want a flat, polished, statement look and can choose your width and length.
• Singapore pendant chain (16/18/20 in): the best base for a pendant — fine, sparkly, and it sits neatly under a collar.
• Mariner / anchor link: a classic, slightly nautical alternative to a rope for men and women.
• Diamond-cut lite rope (2 mm): for a lighter, more delicate everyday chain.
• Rose gold rope and the heavy 11 mm Monaco Cuban: for someone who wants colour or real presence.

Buying tips: insist on "solid 10K," not "gold filled" or "gold plated" — filled and plated pieces are a different product entirely. Check the clasp (lobster is the most secure), and remember a wider chain in the same length weighs and costs more. For pendants, 16–18 inches sits at the collarbone; 20–24 inches wears over a shirt.
