What is the difference between hallmarks and maker's marks?

Have you ever scrutinized those tiny engravings on your gold jewelry or silver, Convinced they held a precious secret? These hallmarks, whether for standardization or maker's marks, do not serve the same purpose: One guarantees the purity of the metal, the other marks the craftsman who shaped it. Discover their key differences to distinguish between the two and ensure your purchases are secure!

Uses of punches

The hallmark - or assay mark - serves to to certify the precious metal content of a piece of jewelry, for example 750/1000 gold orsilver 925/1000. It acts as proof of conformity and quality, particularly important in the jewelry and second-hand market.

The maker's mark, him, identifies the manufacturer or importer : it is a professional signature that links the work to its author. 

In practice, these two marks do not serve the same purpose. The hallmark protects the buyer regarding the nature of the metal, while the maker's mark allows for the traceability of the piece. Together, they form an essential duo to secure a purchase and trace the history of a piece of jewelry. 

Hallmarks, a legal requirement in jewelry

In jewelry, a hallmark is mandatory above certain weight thresholds in France, notably from 3 grams for gold and the platinum, and from 30 grams for thesilver. This requirement gives the jewelry evidentiary value and reassures the buyer about the conformity of the metal. 

The maker's mark is also essential in the professional sector, as it allows for the identification of the manufacturer or importer before the application of the guarantee mark. Customs specifies that there is no exemption from the requirement to use these two marks in this context.

This requirement explains why precious jewelry often bears several marks at once. One of the hallmarks protects the consumer, the other documents the origin of the coin. For resale on the second hand, it is a key indicator to verify the authenticity and consistency of a piece of jewelry. 

Issuing bodies of the hallmarks

The hallmark is part of an official guarantee system: it is applied after the metal has been tested by the customs administration or an authorized body/professional, depending on the countryIn France, this hallmark certifies the purity of the precious metal and complies with a precise regulatory framework.

The maker's mark, however, is borne by the professional himself after registration with the competent guarantee office. Customs specifies that it must be inscribed on a copper plate and that it contains an initial letter as well as a symbol specific to the manufacturer or importer.

Typical shapes of punches

Hallmarks take on standardized shapes and symbols depending on the metal and the country, often featuring animal heads. In France, for example, 18-karat gold is associated with the eagle's head, thesilver at the head of Minerva, and the platinum to other official symbols such as the dog's head depending on the titles. 

The maker's mark has a more personalized form: in France, for precious metals, it is generally presented as diamond-shaped, usually horizontal, framing the manufacturer's initials at both ends and a distinctive symbol in the center, called dispute. It is this highly codified structure that allows one to quickly distinguish the signature of the craftsman from a hallmark. For plated items, the shapes differ, with a square or a pentagon depending on the case, while the responsibility hallmark has yet other shapes for importers. 

Where can I find the hallmarks on my jewelry?

Stamped into the metal, often on the hidden side of the piece of jewelry, hallmarks, whether for fineness or maker's marks, are placed where they do not interfere with either the aesthetic reading or the wearing : inside a ring, on the back of a pendant, on the clasp of a necklace or bracelet, sometimes on the end rings or the post of an earring. This discretion is intentional, as the hallmark must authenticate the work without altering its beauty.

How to correctly read a hallmark?

Reading a hallmark involves first identifying its function: is it a hallmark that guarantees the metal's purity or a hallmark that identifies the manufacturer? Then, you must observe its shape and the symbol it contains. 

When examining antique jewelry, the best approach is to cross-reference several elements. The stated metal, weight, hallmark shape, and the presence of a maker's mark should all be consistent. If any detail seems inconsistent, it's best to request an expert appraisal or compare it with official reference materials. 

In practice, the hallmark answers the question “What is this piece of jewelry made of?” while the master hallmark answers the question “Who made it?” This simple reading already allows for a better understanding of the value of a coin and avoids the most frequent confusions.
