The calculation
18K melt value comes straight from the spot price and its purity:
melt = spot/g × purity × weight(g)
= $148 × 0.75 × 1
= $111 per gramSubtract roughly 15% for a realistic buy-back offer. To value a whole piece, weigh it in grams (a $10 jewelry scale is accurate enough) and multiply by the per-gram figure above.
Should you sell 18K gold for scrap?
- Confirm the purity from the hallmark first. The stamp sets the multiplier — 18K means 75.0% gold. Not sure what the mark says? See the hallmark guide or the karat & alloy reference.
- Weigh it accurately in grams, excluding gemstones and any non-gold clasps or findings.
- Compare offers. Dedicated refiners pay closer to the $111/g melt value; pawn shops and mall "we buy gold" counters usually pay less. A designed or branded piece can be worth more sold intact than melted.
- Not sure of the metal or hallmark? Scan it in the Jewelry Identifier app to read the metal, purity, and stamp from a photo before you negotiate.

- Q. How do I calculate the value of 18K gold?
