How Much Is 31 Grams of 24K 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.

This weight band is common for everyday jewelry lots. Separate by karat first, then compare offers as a % of melt.

Mid-range weights often come from multiple pieces sold together—separate karats first to avoid blended offers.

Weighing & sorting tips

  • If your buyer tests only one spot, ask them to test a second point on repaired pieces (solder areas can read differently).
  • 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.

FAQ

How much is 31 grams of 24K gold worth?
At the live USD spot price we use on MyGoldCalc, 31 g of 24K gold has a rough melt value of about $4,494.38. That is weight × 24K purity × gold price per gram—not a quote to buy your item.
Is $4,494.38 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.

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.
