The gold hallmark: what you need to know
Before buying gold jewelry, it's essential to pay close attention to its authenticity. In France, several factors can be used to verify a piece of jewelry's authenticity and gold content. Hallmarking is a technique used in jewelry making to guarantee the authenticity of the precious metal.
In this article, we will explain how to recognize the different hallmarks on gold jewelry.
What is a gold hallmark on a piece of jewelry?
In the world of jewelry, hallmarking gold is a common technique used to guarantee that a piece of jewelry was indeed made with this precious metal. Using a small tool called a hallmark, the jeweler applies a discreet mark to the jewelry to certify its purity.
But in addition to guaranteeing the authenticity of the jewelry, hallmarking also indicates the gold content of the piece. It's important to know that a gold hallmark is mandatory on jewelry containing 3 grams or more of gold. Platinum and silver hallmarks can also be found on jewelry made with these metals. The hallmark can be a mark with a specific shape, or it can be a small indentation on the jewelry. We will see later that the shape of this engraving is also important.
Hallmarking is a method that also works for materials other than gold, such as steel. It's important to note that the gold hallmark is applied during the jewelry design process or when jewelry made abroad enters France. This serves as a guarantee of the precious metal's authenticity for future buyers.
How to recognize the gold hallmark?
There are several ways to determine if a piece of jewelry is made of gold or not:
- check if the jewelry has an engraving;
- place the gold jewelry near a magnet;
- submerge the jewelry in a bowl filled with white vinegar.
To identify a piece of gold jewelry, you need to look for a hallmark or engraving. In our country, there are several ways to determine if a piece is precious or solid gold. This can all be seen by the shape of the hallmark. On precious metals, the engraving might be a seahorse for 24-karat gold, an eagle for 18-karat gold, a scallop shell for 14-karat gold, and a clover for 9-karat gold. In other words, the gold content varies depending on the animal depicted.
The higher the karat number of the gold, the higher its gold content. For example, when discussing a 9-karat or 18-karat bracelet, the 18-karat bracelet will be more valuable because of its higher gold content. This also explains its higher price. The hallmark may also be a serial number for manufacturing traceability or simply an engraving representing a dot.
Another way to check the purity of a piece of jewelry is to place it near a magnet. It's important to know that gold jewelry is not magnetic. In other words, if your jewelry sticks to the magnet, then you can be certain that the item is not gold.
Finally, there are many ways to identify a piece of gold jewelry, such as immersing it in a container filled with white vinegar. If the object turns black, then the jewelry is most likely gold-plated. However, if the jewelry retains its color and shine, you can be certain it is solid gold.
Where is the gold hallmark located on a piece of jewelry?
Generally, on gold rings, the hallmark is located on either the inside or outside of the band. Therefore, it's important to carefully examine the piece of jewelry from all angles before purchasing it. Furthermore, depending on the type of jewelry, the hallmark may not be in the same place. On a gold necklace or bracelet, the hallmark is most likely located near the clasp.
How many hallmarks should there be on a gold piece of jewelry?
It's important to note that a gold piece of jewelry must bear a specific number of hallmarks to guarantee its authenticity. In fact, it must have at least two hallmarks, representing both the gold content and the gold purity. Therefore, you now know that in France, a genuine gold piece of jewelry (weighing more than 3 grams) will automatically display at least two gold hallmarks.
