14K Solid Gold Box Chain Necklace 1.25mm | Real Gold Box Chain in Yellow, Rose & White Gold

Sleek, strong and timeless — in real 14K gold.

The UXV 14K Solid Gold Box Chain Necklace is made of tiny square links that sit smooth and flat, giving it a polished, liquid-gold shine from every angle. At 1.25mm it's substantial enough to wear on its own, strong enough to carry a pendant, and still refined for everyday layering. Made entirely of solid 14K gold, it won't tarnish, fade or turn your skin green.

• 14" — Choker: sits snug at the base of the neck
• 16" — Collarbone: rests right on the collarbone
• 18" — Most popular: falls just below the collarbone; the go-to length for pendants

• 22" — Neckline: sits at or slightly below the neckline
• 24" — Long: falls toward the chest, great over clothing or as the longest layer

Frequently asked questions

Is this real gold or gold-plated?
Real solid 14K gold through and through — not plated, filled or vermeil. It's stamped 14K and comes with a Certificate of Authenticity.

How thick is the chain?
1.25mm wide — noticeable on its own, but still delicate enough for everyday layering.

Is a box chain strong?
Yes. Box links are tightly connected and don't kink easily, which makes this one of the best chain styles for wearing a pendant every day.

Which length should I choose?
16"–18" is the most popular choice. 20"–22" works well for layering, 12" and 14" are choker lengths, and 24" is a long layer.

Does the price change by color?
No — yellow, rose and white gold are the same price. Only the length changes the price.

How long does it take to arrive?
Your chain is made in 1–4 business days, then shipped by insured express courier with signature required.
