Introduction
As a jewelry brand owner or retailer, one of the most frequent questions you will hear from customers is whether they can wear your pieces in the shower or pool. Stainless steel makes one of the most versatile jewelry options available. It is waterproof with strong intrinsic features, which makes it ideal for use in any environment and activity, including swimming in the pool or when stuck in the rain.
But how waterproof is it, really? At Star Harvest, we have been focusing on brand jewelry customization for 20 years. Having produced over 37 million pieces of jewelry since 2005, we know exactly how this metal performs under pressure. In this guide, we break down the true waterproof capabilities of stainless steel and how to source the best pieces for your brand.
Is 100% Stainless Steel Jewelry Waterproof? (And How It Works)
The short answer is YES. However, stainless steel jewelry is only 100% waterproof when exposed to pure water. Generally, stainless steel jewelry is waterproof enough to withstand daily water contact, especially in its original silver color.
The science behind this lies in its composition. Typically, stainless steel is made up of various compounds, such as chromium, carbon, nickel, molybdenum, and iron, which makes it resistant to corrosion when exposed to pure water. The most important compound is chromium, which must make up at least 10% of the alloy. Chromium is the specific compound that makes stainless steel waterproof. When your stainless steel jewelry is exposed to water, chromium combines with oxygen to create a thin, hard, and resistant oxide layer, which repels any adverse effect possible. The formed layer is so thin that it cannot be seen with the naked eye.
Can Stainless Steel Rust or Tarnish?Yes, it can, but not until a long period of time (years). If it comes in contact with water mixed with chemicals like chlorine or saltwater, it might tarnish over time.
How Plating Affects Waterproofing
Most modern fashion jewelry features gold or rhodium plating. This directly impacts how the jewelry handles moisture:
- Gold-Plated Stainless Steel:Whether gold-plated stainless steel jewelry is waterproof or not depends on the type of PVD plating technique used, the thickness of gold applied, and the purity of the gold. If a thin layer of gold is applied, your jewelry will not be able to withstand prolonged contact with water. On the other hand, if a thicker layer of gold is applied, your jewelry will be very hard to penetrate. Generally, it’s recommended that you use 18K and above for gold plating.
- Rhodium-Plated Stainless Steel:Rhodium-plating is the process of applying a thin layer of rhodium on the surface of a base metal to enhance the beauty and durability. Is it lifetime waterproof? No, it is not lifetime waterproof, but rather, it’s sweatproof. It can withstand splashes of water, as it’s not designed for prolonged immersion or harsh water conditions.
The Star Harvest Advantage: Traditional electroplating can sometimes contain trace irritants or wear off quickly. At Star Harvest, our advanced PVD (Physical Vapor Deposition) 18K Gold, Rose Gold, and Platinum coatings are applied in a vacuum environment. This ensures the plating is not only eco-friendly and hypoallergenic but also lasts 2-3 times longer than competitors.
Daily Wear: Swimming, Showering, and 24/7 Use
To help your customers care for their purchases, it is important to know the boundaries of daily wear.
- Can You Swim With It?Yes, you can swim with stainless steel jewelry because it’s water-resistant and doesn’t rust easily. However, swimming pool water is often treated with chlorine, which is a damaging chemical to jewelry. When your stainless steel jewelry is deep into chlorinated water, it accelerates corrosion.
- Can You Shower With It?Generally, you can wear stainless steel jewelry in the shower on the condition that you don’t use chlorine and other harsh cleaning solutions. If your bathing products contain harsh chemicals, your jewelry can end up corroded.
- Can You Wear It 24/7?Thanks to its properties, waterproof nature, and resistance against extreme conditions, it can be worn 24/7 without adverse effects.
The Best Waterproof Options for Brands
If you are designing a durable jewelry line, these are the best options you can trust to withstand water:
316L Stainless Steel: This is the premium choice. There are high grades of stainless steel jewelry, such as 316L, that can withstand up to 2-5 Parts Per Million (PPM) corrosion from chlorinated water. This grade contains a large quantity of molybdenum, which improves its resistance to several forms of corrosion, as well as exposure to water and sweat.
PVD TIN Layer: This involves the application of a hard, thin layer of Titanium Nitride (TIN) onto the surface of your stainless steel jewelry. PVD coated jewelry offers a protective barrier against water, guaranteeing that your stainless steel jewelry remains intact and free from rusting.
Lifespan and Care TipsWhen made from high-grade stainless steel and designed with durability in mind, your jewelry can easily last for years without tarnishing or wearing out. In fact, PVD gold-plated stainless steel jewelry typically maintains its shine and integrity for at least 2 years, and in many cases, even longer with proper care.
To elongate the jewelry’s life, advise your customers to follow these tips:
During activities that involve contact with sharp objects or abrasive elements, it is important to remove your jewelry beforehand.
Clean your stainless steel jewelry frequently to keep it shiny and new.
Simply use a soft, clean towel and a mild cleaning solution, and do not use abrasive cloth or harsh cleaning solutions.
Store your stainless steel jewelry in a soft cloth bag when you are not wearing it, and do not keep it where it can get tangled with other objects or scratch by tougher materials.
Partnering for Success
Although there are different grades of stainless steel jewelry, only the high-graded ones can be trusted to withstand water and other damaging elements. Therefore, consult a professional custom jewelry manufacturer for the best quality that can be worn 24/7 in any condition without worries.
