Gold Hallmarks & Stamps
Learn how to identify gold hallmarks, stamps, purity marks, maker marks, and numbers such as 375, 417, 585, 750, 916, and 999.
Found 925 on jewelry that looks gold? The stamp normally identifies sterling silver underneath the gold-colored surface. Learn how 925 differs from solid gold, gold plating and vermeil—and how to determine what your jewelry is actually worth.
A 999 stamp on gold means the item is 99.9% pure gold. Learn how 999 compares with 24K, 999.9 fine gold and other common gold purity markings.
A 916 mark generally identifies 22K gold. Learn what the stamp means, how it relates to purity and why testing still matters when estimating value.
A 750 stamp generally indicates 18K gold, or 75% gold content. Learn where the mark appears and how purity, weight and testing affect jewelry value.
A 585 stamp usually means your jewelry is 14K gold, or 58.5% pure gold. Learn what the mark means, how to tell if 585 gold is real, and how its value is calculated.
A 417 mark generally indicates 10K gold. Learn how to interpret the stamp and why a buyer considers tested purity and weight when evaluating your jewelry.
Decode common gold jewelry hallmarks and purity stamps, including karat and fineness markings, and learn why a stamp is a clue rather than proof of authenticity.
