Introduction
In the jewelry industry, obtaining a pristine, white finish is a key challenge that requires advanced technologies. Traditionally, rhodium plating has been a widely used solution. However, it has significant limitations, especially regarding environmental impact and durability. In contrast, Daumet’s 18K White Gold coating, a patented breakthrough, offers a more sustainable and lasting alternative. This article compares the two technologies, highlighting why White Gold coating represents the future of high-end costume jewelry.
1. Rhodium Plating: Understanding the Traditional Approach
What is Rhodium Plating?
Rhodium plating is the process of applying a thin layer of rhodium—a rare and expensive metal—over a base metal (silver, brass, “grey” gold). The purpose is to give the jewelry a bright, white finish.
While rhodium provides a very bright and white allure, it displays various limitations and challenges.
Rhodium plating remains a temporary solution for enhancing the appearance of jewelry, as the very thin coating quickly wears off, especially on items exposed to frequent friction such as rings. This necessitates regular re-plating, which can increase both the cost and maintenance burden over time.
Additionally, rhodium plating involves harmful chemicals and a resource-intensive extraction process. The metal itself is rare, with most of the world’s supply coming from a few mining locations, predominantly in South Africa. This makes the supply chain fragile and subject to strong price fluctuations.
Challenges with Rhodium Plating
- Short lifespan: The thin layer of rhodium wears off quickly over time, the underlying metal (often yellow or gray in color) starts to show through as the rhodium layer wears off and the piece of jewelry needs to be replated
- Sourcing risks: Rhodium is one of the most expensive precious metals, making its use costly, especially with rising prices.
- Environmental impact: Rhodium extraction is polluting and consumes large amounts of water and chemicals, which is increasingly unsustainable. This impact is also increased by the application technology of electroplating which imposes potential health risks on operators and also involves large volumes of chemicals and water.
2. White Gold Coating: A Revolutionary Breakthrough
What is White Gold Coating?
Daumet’s 18K White Gold coating is a patented, cutting-edge solution that overcomes many of the limitations posed by rhodium plating. Developed through years of research and development, this technology uses a gold-tungsten alloy to create the whitest, most durable 18K gold coating available today.
The metal substitution effect with tungsten provides massive environmental and social gains as this technology allows the shift from high impact metals (gold, rhodium) to low impact ones (tungsten) and reduces the global warming potential of the jewelry finishing step by 70% vs. rhodium plating.
The process behind Daumet’s 18K White Gold coating is based on Physical Vapor Deposition (PVD), a waterless and chemical-free method that ensures a long-lasting, environmentally friendly finish. This innovative approach enables jewelers to offer clients a white gold solution that is both precious and sustainable, without the need for constant upkeep.
Unique Advantages of White Gold Coating
- Patented technology: White Gold coating is the result of Daumet’s groundbreaking metallurgical research, making it an exclusive, patented solution unavailable elsewhere.
- Sustainability: Unlike rhodium, the gold-tungsten alloy used in White Gold coating significantly reduces the environmental impact. Tungsten is more abundant and far less polluting to extract than rhodium, gold or platinum.
- Durability: The coating is highly resistant to wear, scratches, and tarnishing. It does not require frequent maintenance or re-coating, providing a cost-effective and long-term solution.
- Preciosity and Aesthetics: White Gold Coating offers the beauty and brilliance of 18K gold, meeting the highest standards of high-end jewelry while ensuring a responsible alternative to traditional finishes.
Why White Gold Coating is a Game-Changer
The creation of Daumet’s 18K White Gold coating was not merely a matter of improving an existing technique but solving a centuries-old challenge in metallurgy. Traditionally, white gold required the use of metals like nickel or palladium—both of which have environmental or allergenic drawbacks—and the rhodium plating process. With Daumet’s patented gold-tungsten alloy, these barriers have been overcome, offering jewelers a genuine white gold solution that is eco-friendly, long-lasting, and precious.

Comparing Rhodium Plating and White Gold Coating: Pros and Cons
Advantages of Rhodium Plating
1. Aesthetic Appeal: Rhodium provides a bright, reflective, white finish, which enhances the brilliance of jewelry, especially white gold.
2. Durability: Rhodium is corrosion-resistant and provides a protective layer that prevents tarnishing.
3. Hypoallergenic: Rhodium-plated jewelry is often hypoallergenic, making it a good choice for sensitive skin.
Disadvantages of Rhodium Plating
1. Frequent Maintenance: Rhodium plating wears off over time, requiring re-plating, especially on rings that undergo more wear.
2. Environmental Impact: The extraction process for rhodium is highly polluting, involving heavy chemical usage and significant water consumption.
3. High Cost: Rhodium is more expensive than gold, which increases the cost of maintaining rhodium-plated jewelry.
4. Lack of customer knowledge: Rhodium plating is not perceived as a key value proposition of jewelry finishing as it know associated with an idea of preciosity in the common knowledge
Advantages of White Gold Coating
1. Sustainability: The gold-tungsten alloy used in Daumet’s 18K White Gold coating is much more environmentally friendly thanks to the massive impact gained from tungsten substitution and alloying with gold. The PVD process furthermore minimizes water use and eliminates harmful chemicals.
2. Preciosity : Daumet’s white gold coating is certified 18K, offering customers a widely known precious option for their jewelry finishes
3. Durability: White gold coating is highly resistant to tarnish, scratches, and environmental wear, maintaining its brilliance without frequent re-coating.
4. Hypoallergenic: Free from nickel and other allergens, white gold coating is a safe choice for people with sensitive skin.
Disadvantages of White Gold Coating
1. Initial Cost: While providing more margin on final product sales thanks to its unique value proposition, the average purchasing cost of white gold coating may be higher than rhodium plating.
2. Color Variation: Some consumers might prefer the exact white sheen of rhodium, although Daumet’s white gold is noted to be the whitest gold coating available.
3. PVD requires the stones to be spared before plating, so the process on stone jewelry can be more complicated than rhodium plating. Daumet is currently developing an automatic process to resolve this technical difference.
