The Truth About Gold-Plated Jewellery — What You Need to Know Before Buying

You have been there. You order a chain online, it arrives looking exactly like the product photo — rich, warm, gold. You wear it for two weeks. Then it starts to fade at the clasp. Then a dark line appears where it sits on your neck. Then the whole thing is greenish-black and in a drawer somewhere.

This is not bad luck. It is not a defective product. It is physics — and the jewellery industry is counting on you not knowing the difference.

Here is the full truth.

Why Standard Gold Plating Always Fails

Standard gold plating — the kind used on the vast majority of affordable jewellery — is a process called electroplating. A metal object is submerged in a solution containing gold ions, an electric current is applied, and a thin layer of gold bonds to the surface.

The keyword is thin. Most commercial gold plating is between 0.5 and 2 microns thick. For reference, a human hair is approximately 70 microns in diameter. Your gold coating is a fraction of that.

At that thickness, everyday wear — friction from clothing, contact with skin oils and sweat, exposure to water and humidity — wears through the gold layer quickly. Once the base metal is exposed, oxidation begins. The result is the tarnishing, discolouration, and green skin staining that is so common with affordable jewellery.

The Industry's Dirty Secret

Jewellery brands know this. They rely on it. A product that fails in two months is a customer who returns to buy another product in two months. It is a business model — but not one that serves you.

The language used in product listings is designed to obscure this reality. "Gold-toned." "Gold-finish." "Gold-coloured." "Gold-plated." All of these mean the same thing: a thin layer of gold on a base metal that will not last.

The exception — the technology that genuinely changes the equation — is PVD.

What PVD Gold Actually Is

PVD stands for Physical Vapour Deposition. Unlike electroplating, PVD is a vacuum-based process. Gold is vaporised in a vacuum chamber and the particles bond directly to the surface of the metal at a molecular level — not just coating the surface but becoming part of it.

The result is a layer that is 5 to 10 times thicker than standard plating, significantly harder, and bonded at a structural level that friction and moisture cannot easily penetrate.

PVD is the same technology used in high-end Swiss watchmaking, aerospace components, and medical devices. It has been adapted for jewellery because it is simply the best coating technology available.

How to Identify Real Quality Before You Buy

• Ask about the coating process. If the brand cannot tell you whether it is electroplating or PVD, assume it is electroplating.
• Look for a warranty. A one-year colour warranty signals that the brand is confident its coating will last. No warranty is a red flag.
• Check the base material. Surgical steel (316L) is the correct base for daily-wear jewellery. Brass and copper corrode faster and transfer colour to skin more readily.
• Test the waterproof claim. Any reputable brand selling waterproof jewellery should be able to demonstrate it. Ask for it. Look for video proof.
• Read the reviews carefully. Customers who have worn a piece for more than three months will tell you the truth that product listings will not.

What This Means for Your Purchase Decision

The price difference between low-quality electroplated jewellery and properly made PVD gold jewellery is smaller than most people expect. At UniqueJewels.in, our PVD gold chains start at Rs. 999 — the same price range as the market chains that will turn black in a fortnight.

The difference is not the price. It is the knowledge of what you are buying.

Buy once. Buy correctly. Wear it every day for the next two years. That is the actual value proposition — and it is one that cheap jewellery can never match.
