About this fineness
Because 958 items are uncommon, they are often priced individually — collectible value can exceed metal value. Weight-based buy-back still follows the same pure-content formula as any fineness.
23K alloy is 95.80% pure gold. So one troy ounce of pure metal takes 32.5 g of this alloy, and a 10 g item holds 9.58 g of gold.

Frequently asked questions
How much is 1 gram of 23K gold today?
The pure-gold content of 1 gram of 23K alloy is worth about $128.32 (95.80% 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 (95.8% of the item's weight) minus a refining/risk discount. Craftsmanship, brand and stones do not count in scrap pricing.
How does 958 fineness map to karats?
958 fine equals 23K: one karat is a 1/24 share of gold, so karats = fineness × 24 ÷ 1000.
