How Much Is 80 Grams of 18K Gold 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.

Heavier pieces often include hollow construction. Two similar-looking chains can differ by many grams—trust the scale, not the look.

Heavy lots reward checking for non-gold inserts and solder-heavy joints—buyers may test and adjust the offer.

Weighing & sorting tips

  • If the item is plated or filled, it won’t follow karat melt math; check stamps like GF/GP/HGE before using a gold-only estimate.
  • If the item feels “too light,” it may be hollow; value is still weight-based, so grams matter more than looks.

FAQ

How much is 80 grams of 18K gold worth?
At the live USD spot price we use on MyGoldCalc, 80 g of 18K gold has a rough melt value of about $8,699.20. That is weight × 18K purity × gold price per gram—not a quote to buy your item.
Is $8,699.20 what a pawn shop will pay?
Usually not. Pawn shops and many buyers pay a percentage of melt—often roughly 50–70% for quick cash purchases. Online buyers may pay a higher percentage. Always get multiple offers.
What if my lot has mixed karats?
Separate by stamp (10K/14K/18K etc.) and weigh each group. A single blended offer for mixed karats is often lower than itemized pricing.
Does 18K gold price change every day?
Spot gold moves with the market. Our pages refresh on a regular schedule (ISR). Use the same spot basis as our calculators when comparing numbers.
