Yes. Gold Scanner is built as a karat checker for the full common range — 24K, 22K, 18K, 14K and 10K. It cross-references visible stamps (999, 916, 750, 585, 417), color tone, and hallmark patterns to estimate purity, then converts to fineness or millesimal scale on request.
The hallmark identifier recognizes common purity stamps (24K, 22K, 18K, 14K, 10K, 999, 916, 750, 585, 417), country assay marks, designer and maker stamps, and date letters. It works across jewelry, coins, bars, and antique pieces from major gold-producing regions.
Gold Scanner pulls live market spot prices and combines them with detected karat purity and weight to produce an estimated USD value. Estimates are accurate enough for quick triage and resale comparison, but for insurance, pawn loans, or legal appraisal we recommend confirming with a certified precious metals expert.
