About this fineness
The value-versus-durability balance makes 18K the standard for fine jewellery. Buy-back counts metal only — brand and craftsmanship are not reimbursed, so the gap between boutique price and scrap value peaks at this fineness.

Frequently asked questions
How much is 1 gram of 18K gold today?
The pure-gold content of 1 gram of 18K alloy is worth about $97.02 (75.00% of the per-gram market price). Retail sells above this value; buy-back pays below it.
Why do pawnshops pay less?
Buy-back values only the pure gold (75.0% of the item's weight) minus a refining/risk discount. Craftsmanship, brand and stones do not count in scrap pricing.
How does 750 fineness map to karats?
750 fine equals 18K: one karat is a 1/24 share of gold, so karats = fineness × 24 ÷ 1000.
