How Much Is a 18K Gold Necklace Worth?
Estimates use the same USD spot basis as our calculators. Not financial advice, not a purchase offer, and not a guarantee of what any buyer will pay.
Necklace weight varies significantly by style. A delicate chain may be 3–5g; a thick rope chain can exceed 20g. Weigh the chain separately from any pendant.
Necklaces vary wildly by chain style—rope and Cuban links can be much heavier than a fine box chain of the same length.
For a typical weight in the common range, ~5 g of 18K gold might melt around $543.70 at current spot—highly variable by actual weight and condition.
Common variations that change weight
- Repairs and solder add metal that may test differently than the rest of the piece.
- Hollow vs solid construction can change grams dramatically even when the piece looks similar.
