These small markings on your favorite pieces of jewelry carry great meaning and provide valuable information about the origin, material and quality of the jewelry. In this blog post, you will learn everything you need to know about jewelry hallmarks and why they are so important.

What are jewelry stamps?

Jewelry stamps, also known as hallmarks, are small markings placed on jewelry pieces. They serve as identification marks and provide information about the manufacturer, the material used and the purity of the metal. These stamps are often tiny and placed in inconspicuous places on the jewelry so as not to affect the aesthetics.

The different types of jewelry stamps

  1. Fineness stamp

The fineness stamp indicates how much pure precious metal is contained in an alloy. This is especially important for gold, silver and platinum, as these metals are often mixed with other metals to make them more durable. Here are some of the most common fineness stamps:

  • Gold : 999 (24 carat), 916 (22 carat), 750 (18 carat), 585 (14 carat), 375 (9 carat)
  • Silver : 999, 925 (sterling silver), 835, 800
  • Platinum : 999, 950, 900, 850

For example, a 925 silver stamp means that the piece of jewelry is made of 92.5% pure silver.

  1. Manufacturer stamp

The manufacturer's stamp identifies the manufacturer or designer of the piece of jewelry. This can be a symbol, a logo or a combination of letters. For collectors and lovers of branded jewelry, this stamp is particularly important as it confirms the authenticity and origin of the jewelry.

  1. Test mark

Hallmarks or official hallmarks are official stamps that confirm that the piece of jewelry has been tested for its fineness by a recognized testing center. These marks vary from country to country and are a guarantee of the quality of the metal. However, these marks are not mandatory and are therefore not often found.

  1. Annual stamp

Some jewelry, especially antique pieces, have year stamps indicating the year of manufacture. These stamps are especially valuable to collectors because they help determine the age and history of a piece of jewelry.

The importance of jewelry stamps

Jewelry stamps carry a variety of important information and offer several advantages:

  1. Authenticity : Jewelry hallmarks help confirm the authenticity of a piece of jewelry. This is especially important when purchasing expensive or antique jewelry to avoid counterfeits.

  2. Quality : The stamps provide information about the quality and fineness of the metal. A high fineness means that the piece of jewelry contains a high proportion of pure precious metal, which increases its value.

  3. Value : Jewelry hallmarks can increase the value of a piece of jewelry, especially if it is from a well-known designer or manufacturer. Collectors place great value on well-documented and hallmarked pieces.

  4. Legal Compliance : In many countries, assay marks are required by law to ensure that the fineness of precious metals is correctly stated. This protects consumers from fraud and misrepresentation.

  5. Traceability : Jewelry hallmarks provide a way to trace the origin and history of a piece of jewelry. This is especially valuable for heirloom and antique jewelry as it helps document their history and provenance.

Tips for interpreting jewelry stamps

Reading and interpreting jewelry stamps can sometimes be challenging, especially when the stamps are small or worn. Here are some tips to make deciphering easier:

  1. Magnification : Use a magnifying glass or jeweler's loupe to get a better look at the stamps. This makes it easier to see small details and symbols.

  2. Reference Charts : Have reference charts handy that explain the different stamps and their meanings. There are many online resources and books that can help you identify the stamps.

  3. Professional help : If you are unsure, consult a jeweler or jewelry expert. They can help you interpret the hallmarks and determine the authenticity and value of your piece of jewelry.


Jewelry hallmarks are small but extremely meaningful markings that can reveal a lot about a piece of jewelry. They confirm the authenticity, quality and origin of the jewelry and provide important information for collectors and buyers. By understanding and interpreting jewelry hallmarks, you can make informed decisions when purchasing and caring for your jewelry. So, next time you hold a piece of jewelry in your hands, take a closer look at the hallmarks - they have a lot to tell!

Happy jewelry shopping and stay curious!
