PVD Coating vs. Gold Plating: Why Your Jewellery Keeps Tarnishing

It’s a familiar frustration for anyone in the UK who loves gold jewellery: you buy a gorgeous necklace or pair of hoops, wear them out a handful of times, and within a few weeks, they lose their shine. Worse still, they leave a faint green ring on your skin or reveal a dull, copper-toned metal underneath.

Whether it’s humidity, a sudden British downpour, or a workout at the gym, standard fashion jewellery often struggles to keep up with everyday life.

The culprit? Traditional gold electroplating.

However, modern jewellery design has shifted towards a process called PVD (Physical Vapour Deposition) coating. To understand why your jewellery keeps tarnishing and how to stop buying pieces you have to replace every season, the key lies in the science behind these two techniques.

Why Traditional Gold Plating Tarnishes

Traditional gold-plated jewellery is made by submerging a base metal—usually brass, copper, or low-grade alloy—into a chemical bath containing gold ions. An electric current deposits a microscopic layer of gold over the metal.

While electroplated pieces look radiant on day one, the finish sits on top of the metal like a delicate coat of paint.

The Chemistry of the "Green Skin" Reaction

1. Friction & Wear: Daily contact with skin, clothing, perfume, and water rapidly wears away the thin electroplated layer.

2. Exposed Base Metals: Once the micro-thin gold layer chips or thins out, the brass or copper base underneath is exposed to air and moisture.

3. Oxidation: Copper and brass react chemically with sweat, water, and oxygen (oxidation). This forms copper carbonate—the exact compound that tarnishes your jewellery dark brown and leaves a greenish residue on your skin.

The Solution: What Is Gold PVD Coating?

Physical Vapour Deposition (PVD) is a high-tech vacuum coating process adapted from aerospace and medical manufacturing.

Instead of dipping metal in liquid chemicals, the jewellery is placed inside a high-temperature vacuum chamber. Real 18k gold is vaporized into a plasma state and blasted onto a 316L Surgical Grade Stainless Steel base.

Rather than sitting on top of the metal, the gold atoms fuse directly into the surface of the steel at a molecular level.

Comparison: PVD Coating vs. Traditional Gold Plating

To highlight the contrast, here is how the two methods perform side-by-side:

3 Reasons Why PVD Jewellery Outperforms Standard Plating

1. You Never Need to Take It Off

With standard gold plating, care instructions usually advise avoiding showers, perfume, swimming, and workouts. Because 316L stainless steel does not rust and PVD coating does not react to moisture, PVD jewellery is completely shower-safe and waterproof.

2. It’s Hypoallergenic and Gentle on Sensitive Skin

Most skin irritation caused by cheap jewellery stems from nickel, brass, or copper leaching out once the plating wears off. Surgical grade 316L stainless steel is biologically inert, making it ideal for sensitive skin and daily ear stacks or neck chains.

3. Better Cost-per-Wear Value

A £15 gold-plated necklace that turns brassy after three months costs far more over time than investing in quality everyday staples. A PVD-coated piece keeps its warm 18k gold lustre for years, giving you true low-maintenance luxury.

Designed for Everyday Life

You shouldn't have to treat your everyday jewellery like fragile glass. Understanding the difference between gold plating and PVD coating makes it easy to choose pieces that suit an active, modern lifestyle without sacrificing elegance.
