How Much Is 4.5 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.
Light-weight pieces (roughly under 10 g) are common for single rings, small chains, or earrings. Heavier items add up quickly—compare with a kitchen scale.
Light-weight totals often match one ring, a delicate chain, or small earrings. If stones are present, gold-only weight may be lower than total weight.
At the live spot used on this site (USD), 4.5 g of 18K gold has a rough melt value of about $489.33. This is not a purchase offer—just an estimate from spot × weight × purity.
Weighing & sorting tips
- If a shop quotes a number fast, ask what % of melt they’re paying—percent clarity beats guessing.
- Weigh without stones when possible; stone settings add weight but not scrap metal value for most buyers.

- 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.
