Frequently asked questions
How much is 1 gram of 9K gold today?
The pure-gold content of 1 gram of 9K alloy is worth about $50.23 (37.50% 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 (37.5% of the item's weight) minus a refining/risk discount. Craftsmanship, brand and stones do not count in scrap pricing.
How does 375 fineness map to karats?
375 fine equals 9K: one karat is a 1/24 share of gold, so karats = fineness × 24 ÷ 1000.
