Metals and punches
Gold is one of the most precious metals, highly prized in the world of jewelry. Used for thousands of years for its beauty and durability.
The different types of gold and their uses
Gold used in jewelry comes in several varieties depending on its purity and alloys. Each type of gold offers unique characteristics in terms of cost, durability, and aesthetics. Learn about the distinctions between gold plated, 9 karat gold, 14 karat gold, and 18 karat gold:
Gold Plated
Gold plating consists of a thin layer of gold applied to a base metal, such as copper or silver. Although less expensive, it offers the appearance of solid gold without the price. It is widely used in jewelry.
9 carat gold
9 karat gold contains approximately 37.5% pure gold, with the remainder made up of other metals such as copper and silver. This type of gold is more affordable and more scratch-resistant, making it ideal for everyday jewelry.
14 carat gold
At 58.3% pure gold, 14 karat gold offers a good balance between purity, durability and price. It is often used for wedding rings and jewelry requiring increased strength.
18 carat gold
18k gold is made up of 75% pure gold, which gives it a rich golden color and high value. It is the preferred choice for luxury jewelry due to its superior quality and shine.
All creations from Maison Naomie Richard are made exclusively in 18-carat gold to accompany you throughout your story.
Gold and its alloys
An alloy is a combination of two or more metals melted together to achieve specific properties. Gold is often alloyed with other metals to create different shades and improve its strength.
Discover the different gold alloys used within the House:
Yellow Gold
To make yellow gold, about 12.5% copper and 12.5% silver are added to 18-karat gold. This alloy retains the classic golden color while being durable and versatile.
Rose Gold
Rose gold is created by adding approximately 20% copper and 5% silver to 18k gold, giving it a distinctive and romantic pink hue that is very popular in contemporary jewelry.
White Gold
White gold is made by mixing about 75% pure gold with about 25% white metals such as palladium or nickel. It is often plated with rhodium for a brilliant shine. It is prized for its modern elegance and its similarity to platinum.
The punches
Hallmarks are marks placed on jewelry to ensure its authenticity and purity. There are two main types of hallmarks:
The State hallmark
The state hallmark, also known as the guarantee hallmark, is affixed by an official authority. In France, this hallmark attests to the precious metal content of the jewel. For 18-carat gold, the hallmark is often an eagle's head.
The Master's Hallmark
The master's mark is a mark specific to each jewelry manufacturer. It identifies the craftsman or company that made the piece. This hallmark is often a unique signature or symbol specific to the jewelry workshop.
On our jewelry, the State hallmarks are systematically present. Unlike the Master hallmark which will only be present on creations containing more than 3 grams of Gold.
Gold Mining and Recycled Gold
Gold mining is often associated with controversial mining practices, involving deforestation, water pollution and poor working conditions for miners. These abuses have a significant environmental and social impact.
Aware of these issues, we have chosen to use only recycled 18-carat gold for our creations. This recycled gold comes from old jewelry, industrial debris or used electronic components.
By recycling gold, we reduce mining and our ecological footprint, while supporting more responsible and sustainable jewelry, with the commitment to offer you jewelry that respects our planet.
