Understanding Gold Markings & Stamps

Gold EducationJewelry

The tiny stamps and marks on gold jewelry tell a story — about purity, origin, manufacturer, and sometimes even the era in which a piece was made. Learning to read these markings helps you understand what you own before selling.

Purity Marks

The most common marks indicate gold purity:

### Karat Marks

  • **24K** or **24 Karat**: Pure gold (99.9%)
  • **18K** or **18 Karat**: 75% gold
  • **14K** or **14 Karat**: 58.3% gold
  • **10K** or **10 Karat**: 41.7% gold
  • ### Percentage Marks

  • **999**: 99.9% pure gold
  • **750**: 75% gold (equivalent to 18K)
  • **585**: 58.5% gold (equivalent to 14K)
  • **417**: 41.7% gold (equivalent to 10K)
  • ### Regional Variations

  • **.750** or **750** is common in European and Asian jewelry
  • **18K** is standard in the Philippines and many Asian countries
  • **14K** is common in the United States
  • **9K** (37.5% gold) is legal in some countries but rare in the Philippines
  • Maker's Marks

    Jewelry manufacturers stamp their pieces with identifying marks:

  • Luxury brands have distinctive logos (Cartier, Tiffany, Bulgari)
  • Individual artisans may use initials or symbols
  • Manufacturer codes help trace origin and authenticity
  • Hallmarks

    In some countries, official assay offices stamp gold with hallmarks that indicate:

  • Purity (verified by testing)
  • Manufacturer
  • Year of production
  • Country of origin
  • What If There Are No Marks?

    Unmarked gold is common, especially in:

  • Traditional or handmade jewelry
  • Older pieces where marks have worn away
  • Pieces from regions where marking is not mandatory
  • Gold bars or raw gold
  • Absence of marks does not mean a piece is not genuine — it simply requires professional testing.

    Fake Marks

    Unfortunately, counterfeit gold sometimes carries fake marks:

  • Stamps may be superficial or poorly executed
  • Numbers may not correspond to actual purity
  • Brand marks may be misspelled or misaligned
  • Professional testing is the only reliable way to verify gold purity regardless of markings.
