What is 3-micron gold plating? Definition and difference

Qu’est-ce que le plaqué or 3 microns ? Définition et différence

What is the difference from “fine gold-plated” jewelry?

3-micron gold plating is now the quality benchmark for high-end gold-plated jewelry. This designation meets precise legal criteria and guarantees excellent durability.

Gold-plated jewelry with 3 microns and fine gold-plated jewelry are made with a brass base and a certain thickness of gold. The difference between the two lies in the thickness of the plating, which is expressed in microns.

Very precise legal criteria make it possible to distinguish between the different designations:

Legally, we may use the term “gold-plated” when the plating is at least three microns thick. This is the highest quality available for fashion jewelry.

The term “3-micron gold plating” refers to a manufacturing process in which a thin layer of gold is deposited onto a base metal (brass, in our case). The mention “3 microns” indicates the thickness of this gold layer, approximately three thousandths of a millimeter. The thicker the layer, the more durable and wear-resistant the jewelry. Thus, 3-micron gold plating is very high quality, offering an elegant appearance and a shine similar to that of pure gold, while remaining affordable.

In contrast, fine gold-plated jewelry has a very thin layer of gold, well below three microns. This jewelry does not retain its original gold color for as long as gold-plated jewelry.

What is the 18-karat gold that we use?

18-karat gold, often used in fine jewelry, refers to an alloy composed of 75% pure gold and 25% other metals, such as silver, copper or nickel. This proportion ensures a certain level of durability while preserving gold’s beauty and richness. The term “karat” refers to the purity of gold, with 24 karats corresponding to 100% pure gold. Because it is blended with other metals, 18-karat gold offers the perfect balance between durability and shine, making it an excellent choice for quality jewelry.
