What makes jewelry really waterproof? The technology explained

The secrets of waterproof jewelry revealed

Waterproof jewelry is the perfect choice for an active lifestyle. Whether you're swimming, showering or playing sports - you don't have to take off these robust pieces. But what exactly makes jewelry waterproof? We'll explain the technology behind it.

Special coatings for maximum durability

The key to waterproof jewelry is special coatings and alloys that protect the metal from corrosion and oxidation. A rhodium or ruthenium alloy is often used, which creates an extremely hard and scratch-resistant surface.

Another option is PVD coating (Physical Vapour Deposition). This involves coating the metal with ions from precious metals such as gold or platinum in a vacuum chamber. The ions bind firmly to the carrier material and form an extremely robust and waterproof layer.

Stainless steel - the all-rounder among jewellery metals

Stainless steel is particularly suitable for waterproof jewelry because it is naturally very corrosion-resistant. The alloy of iron, chromium and nickel forms a passive oxide layer that protects the metal from tarnishing.

To make it even more robust, stainless steel is often additionally coated, for example with PVD gold plating. This creates scratch-resistant and waterproof jewelry that is still affordable.

High-quality gold plating for shine and color fastness

Special processes are also used to make yellow gold or white gold jewelry waterproof. A thick rhodium alloy on the surface protects the precious metal from discoloration and oxidation.

The rhodium layer is also extremely scratch-resistant and allows the gold plating to shine unchanged for many years - even with frequent contact with water. With the right technology, you can wear your jewelry without any restrictions. Invest in high-quality, waterproof pieces and enjoy jewelry that will stay beautiful for years.
