Long reserved for industry, stainless steel has revolutionized the world of jewelry. More resistant than silver and more affordable than gold, it offers an excellent alternative to precious metals.
But not all steels are created equal when it comes to being worn against the skin. There are several types of stainless steel used in jewelry, each possessing different properties.
In this article, I will decode the different types of stainless steel, their characteristics, and which ones you should favor for your jewelry.
What is stainless steel?
Stainless steel, often called inox steel or stainless steel, is an alloy composed mainly of iron and chromium.
Chromium plays a key role: it forms a thin invisible protective layer, called a passive layer, which protects the metal against corrosion and oxidation.
Thanks to this property, stainless steel offers characteristics that are particularly sought after in jewelry:
- excellent resistance to corrosion
- great long-term durability
- resistance to water, perspiration, and humidity
- easy daily maintenance
- shiny and modern appearance
These qualities make it a material of choice for the creation of jewelry such as necklaces, bracelets, rings, or earrings.
Why has stainless steel become essential in jewelry?
Beyond its technical properties, stainless steel is now established as a material perfectly suited for everyday jewelry.
1. A metal designed to be worn every day
Stainless steel does not tarnish, does not blacken, and retains its shine even when in contact with water, perspiration, or daily products.
2. Excellent skin tolerance
Quality steels, such as 316L or 304, are generally well-tolerated by the skin and limit the risk of irritation.
3. Durability that stands the test of time
Unlike other metals, stainless steel is unalterable: it retains its appearance and structure for many years.
4. A more responsible choice
Stainless steel is a fully recyclable and durable material, which makes it an interesting option in a more conscious approach.
The 3 dominant steel grades in jewelry
Not all stainless steel grades are suitable for prolonged contact with the skin. Here are the three most common types in jewelry.
How to recognize quality stainless steel jewelry?
Here are 3 tips to help you choose quality stainless steel jewelry that is durable, aesthetic, and safe:
-
Observe the finish: Quality stainless steel jewelry generally features a smooth and uniform surface, a shiny or polished appearance, and good scratch resistance. An irregular or dull finish may be a sign of inferior quality.
-
Pay attention to the color: High-quality stainless steel, such as 304 or 316L, is distinguished by a homogeneous hue and subtle cool reflections. Conversely, a color that is too bright (very vibrant gold or silver) may indicate lower quality plating or a less durable alloy.
-
Check the brand's transparency: Trusted brands generally state the type of steel used, the material's properties, and maintenance tips. This information is often a good indicator of quality and seriousness.
Understanding plating: gold or rose-gold stainless steel
Stainless steel is naturally silvery-gray. To obtain gold or rose-gold stainless steel jewelry, the PVD (Physical Vapor Deposition) plating technique is used.
Unlike classic "flash" plating, PVD vaporizes metal, often nitrided titanium mixed with gold, under vacuum. The result is a color fused to the steel, which is extremely resistant to wear.
FAQ - Everything you need to know about stainless steel jewelry
Can I shower with my steel jewelry?
Yes. 316L and 304 stainless steel perfectly resist clear water and soap. This is one of its greatest advantages compared to brass or silver-plated metal. Just remember to rinse the jewelry with fresh water after swimming in the sea or a pool.
How do I clean stainless steel jewelry?
A soft cloth and a little soapy water are sufficient. If the jewelry is engraved, a soft toothbrush can dislodge impurities in the recesses. Avoid abrasive products that could scratch your jewelry. Discover all the best practices in the jewelry care guide.
Does stainless steel contain nickel?
Yes, the majority of stainless steels contain a small amount of nickel to ensure their strength. However, in 316L steel, the nickel is "trapped" in the molecular structure and is not released onto the skin, which makes it hypoallergenic for most people.
Does stainless steel turn yellow over time?
No. Unlike 925 sterling silver, which oxidizes by turning black, or base metal, which eventually yellows, natural steel keeps its color. For gold-tone jewelry, the durability will depend on the quality of the PVD plating, but it is far superior to that of classic fashion jewelry.
Do stainless steel jewelry pieces oxidize?
No. Stainless steel is designed to resist corrosion. Jewelry made of 316L and 304 steel generally does not oxidize under normal conditions of use. They retain their shine for a long time and require little maintenance.
Is stainless steel good for the skin?
316L (surgical steel) and 304 stainless steels are generally well-tolerated by the skin. 316L, thanks to its very low releasable nickel content, is particularly recognized for its hypoallergenic properties and is suitable for sensitive skin. 304 also offers good daily tolerance, making it a reliable option for the majority of jewelry.
Conclusion
Stainless steel has established itself today as one of the most appreciated materials in jewelry, thanks to its resistance, durability, and timeless aesthetic.
Among the different grades, 316L and 304 stainless steels stand out for their excellent properties for jewelry: resistance to corrosion, comfort against the skin, and great longevity.
Understanding the types of stainless steel better allows you to make informed choices and favor jewelry that is durable, elegant, and made to last over time.
