How Much Is 1 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.

Micro weights are easy to misread on a kitchen scale—use a 0.01 g jewelry scale for a reliable estimate.

Light pieces can include steel springs or plated parts; a quick magnet check helps, but testing is better than guessing.

Weighing & sorting tips

  • If the piece is tiny, weigh it with a small container, then subtract the container tare (don’t try to balance it on the edge).
  • If your pieces are mixed-karat, weigh each karat separately; otherwise a blended estimate can mislead you.

How we calculate melt

This page uses our live USD per-gram rate for 18K (derived from spot and purity), not the headline 24K figure alone. In words: 1 g × 18K alloy × $109.10/g ≈ $109.10 full metal value before any buyer haircut.

What buyers might pay for this weight (illustrative)

Dealers pay a share of melt. Below uses the same total melt as this page ($109.10). For tiny lots, some buyers have minimum fees—combine pieces before selling so fees don’t dominate the payout.

FAQ

How much is 1 grams of 18K gold worth?
At the live USD spot price we use on MyGoldCalc, 1 g of 18K gold has a rough melt value of about $109.10. That is weight × 18K purity × gold price per gram—not a quote to buy your item.
Is $109.10 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.
Should I remove stones or clasps before weighing?
If you can do it safely, weigh gold-only metal; stones and some clasps add weight but often don’t increase scrap payout. If you can’t remove them, ask how the buyer deducts non-gold parts.
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.
