"18K gold plated" sounds precise, but most people buying it don't actually know what the number means or how to tell good plating from poor plating. Here's what's actually being described.

What the karat number means

The karat number describes the purity of the gold used, not how much of it is on the piece. Pure gold is 24K. 18K gold is 75% gold, alloyed with other metals for strength — the same standard used in fine solid gold jewellery, not a lesser version invented for plating.

So 18K gold plating means a genuine 18-karat gold alloy has been used for the layer on top. It says nothing about how thick that layer is, which is the part that actually determines how long a piece lasts.

What actually determines durability: thickness

Plating thickness is measured in microns, and this is where quality genuinely varies between brands. Very thin "flash" plating, sometimes under half a micron, is common in fast fashion jewellery and can wear through within weeks of regular wear. Thicker plating, several microns, lasts substantially longer under normal conditions.

This is the detail that almost never appears on a product listing, and it's the real difference between plated jewellery that disappoints and plated jewellery that doesn't.

What's underneath matters just as much

Plating over a poor base metal fails faster regardless of thickness, because the base itself reacts with air and skin once the plating wears anywhere at all. Plating over solid sterling silver behaves very differently to plating over brass — silver is far less reactive, so even light wear doesn't expose something that discolours or irritates skin underneath.

Why plated jewellery exists at all

Solid 18K gold jewellery is priced by the gram of actual gold content, which puts even a simple piece well beyond most everyday budgets. Plating gives the same gold-toned look and the genuine feel of gold at the surface, at a fraction of the cost, because you're paying for a fine layer rather than a solid piece throughout.

This isn't a compromise or a lesser category — it's a different, legitimate way of making gold-toned jewellery accessible, used by brands across every price point, including many that don't advertise it as plainly as they should.

What actually extends the life of a plated piece

A protective coating. A thin transparent e-coating sealed over the plating acts as a barrier against air, water and the natural oils on skin — all of which are what wear plating down over time. This is a manufacturing choice some brands make and others skip.

How it's worn. Perfume, lotion, and swimming all speed up wear regardless of plating quality. Jewellery on last, off first, is the simplest rule.

How it's stored. Dry, separate from other pieces, away from bathroom humidity.

Where ANVIRA sits

Every ANVIRA gold piece is 18K gold plated over genuine 925 sterling silver, not brass, and finished with a protective e-coating. We won't claim it never wears — no plated piece can honestly claim that — but the combination of a precious metal base and a sealed finish is built to outlast typical plated jewellery by a meaningful margin.
