How Much Is 21 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.
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.

- Is $2,283.54 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.
