How Heavy Should a Real Gold Chain Be: Weight Reference Guide

August 29, 2026

The weight of a gold chain in grams is the single most important number in any gold jewelry purchase. It determines the metal value, confirms whether the construction is solid or hollow, and tells you whether the price you are being asked to pay is fair or not. This guide gives you the reference weights for every major chain style and size so you can verify any chain before buying.

Why Gram Weight Is the Most Important Number

Gold is priced as a commodity — by weight, by purity. The gram weight of a chain combined with its karat tells you exactly how much gold it contains and therefore what it is worth at any given day's spot price. A seller who cannot or will not tell you the gram weight of a specific chain variant is hiding the most important piece of information in the transaction. Every legitimate gold jewelry seller specifies gram weight. At FJNYC, it is listed for every variant of every product.

Reference Weights — Solid 10K Cuban Link Chain

3mm · 20in: 12–17g
4mm · 20in: 17–24g · 22in: 19–27g
5mm · 20in: 30–38g · 22in: 32–42g · 24in: 35–46g
6mm · 22in: 40–54g · 24in: 44–59g
7mm · 22in: 54–72g · 24in: 59–79g
8mm · 22in: 70–95g
10mm · 22in: 105–145g

Reference Weights — Solid 14K Cuban Link Chain

14K chains weigh approximately 40% more per gram than 10K chains of the same dimensions because 14K gold is denser. Multiply the 10K reference weights above by 1.38 to get approximate 14K solid weights.

Reference Weights — Rope Chain (Solid)

2.5mm · 20in: 8–12g
4mm · 22in: 16–22g
5mm · 22in: 22–30g
6mm · 22in: 30–40g

Reference Weights — Franco Chain (Solid)

2mm · 22in: 12–18g
3mm · 22in: 20–28g
4mm · 22in: 32–44g
5mm · 22in: 50–68g

Hollow Chain Weights

Hollow chains typically weigh 20 to 35 percent as much as solid chains of the same stated dimensions. A hollow 5mm Cuban link at 22 inches weighs approximately 8 to 15 grams — compared to 32 to 42 grams for the solid version. If a chain falls significantly below the solid reference weights above for its stated size, it is hollow regardless of what the listing says.

How to Use These Numbers

Before buying any gold chain: ask for the gram weight of the specific variant you are considering. Compare that weight to the reference ranges above for that style, width, and length. If the weight falls within the solid range, the chain is solid. If it is significantly below, it is hollow. Then apply the price check: gram weight × current spot price per gram for that karat = metal value. A fair retail price is 40 to 80 percent above that metal value.
