Hallmarks are discreet yet incredibly valuable marks engraved on precious metal jewelry. They tell the story of each piece, revealing essential information about its origin, quality, and authenticity. Whether you are a lover of antique and vintage jewelry or a seasoned collector, understanding these small marks is crucial to fully appreciating the value of your pieces. This detailed guide will help you decipher jewelry hallmarks.
What is a Jewelry Hallmark?
A hallmark is an official mark, often stamped on the metal of a piece of jewelry, certifying its content of precious metals (such as gold, silver, or platinum) and its origin. Hallmarks have been used for centuries to guarantee the quality of materials used in jewelry making. Each country has its own hallmarking system, with specific symbols and numbers indicating the purity and origin of the metals.
The History of Hallmarks
The hallmarking of precious metals dates back to antiquity, but the system became formalized during the Middle Ages. In France, the use of hallmarks was codified under the reign of Charles VII in the 15th century. Since then, every piece of jewelry made or imported into France must bear hallmarks to attest to its compliance with quality standards. Other European countries have also established similar systems, each with its own symbols and regulations.
The Different Types of Hallmarks
Maker's Mark

Symbol: In France, it typically takes the form of a diamond shape containing the artisan's initials and a symbol.

Assay Mark:
Description: Indicates the purity of the precious metal used.
Symbol: For example, a piece of 18-carat gold jewelry will bear a hallmark representing an eagle's head in France, while a piece of platinum jewelry will bear a dog's head.

How to Read Hallmarks
The placement of hallmarks varies depending on the jewelry. They can be located inside a ring, on a necklace clasp, or on the underside of a bracelet. Use a magnifying glass to closely examine these marks. Here are some common hallmarks and their meanings:
Eagle's Head: 18-carat gold
