Gold Filled vs. Gold Plated: What's the Difference and Why It Actually Matters

If you've ever bought a piece of gold jewelry that looked perfect in the store and turned your skin green three weeks later, you already understand why this matters.

Not all gold jewelry is created equal. And when you're investing in a handmade piece you want to wear for years — not months — knowing the difference between gold filled and gold plated can save you a lot of disappointment.

Here's everything you need to know, in plain language.

Gold Plated: The Basics

Gold plated jewelry is made by depositing a very thin layer of gold onto a base metal (usually brass or copper) through an electroplating process. The gold layer is measured in microns — and it's thin. We're talking anywhere from 0.5 to 2.5 microns typically.

What does that mean in practice? It means that over time — sometimes quickly — that thin layer wears away. Sweat, water, friction, and body chemistry all accelerate the process. You're left with the base metal showing through, which can tarnish, discolor, and in some cases irritate sensitive skin.

Gold plated pieces can look beautiful when they're new. But they're not built to last.

Gold Filled: What Makes It Different

Gold filled jewelry is a completely different construction. It's made by pressure-bonding a thick layer of solid gold to a base metal core — typically brass. In the United States, gold filled pieces must contain at least 5% gold by weight, which is legally regulated.

That layer of gold is 50 to 100 times thicker than gold plating.

What that means for you: gold filled jewelry is durable, long-lasting, and with basic care, can last decades. It won't flake, chip, or peel the way plated jewelry does. It's also safe for most people with sensitive skin or metal allergies, because the gold layer is thick enough that the base metal rarely makes contact with your skin.

Why RILLA Uses Gold Filled

Honestly? Because I wear my own jewelry everywhere.

To the gym. In the shower. To sleep. To the pool. I am not precious about it — and I didn't want to make pieces that required that kind of care. I wanted to make something you could actually live in.

I chose gold filled because it's the closest you can get to solid gold without the solid gold price tag. It behaves like gold. It looks like gold. And if you treat it even halfway decently — which, as I mentioned, I do not always do — it will last you a very long time.

My goal has always been to use the highest quality materials I can while keeping my pieces accessible. Gold filled lets me do that.

What About Gold Vermeil?

You might also see gold vermeil (pronounced ver-MAY) when you're shopping for jewelry. Vermeil is similar to gold plating but with two key differences: it uses sterling silver as the base metal instead of brass or copper, and the gold layer must be at least 2.5 microns thick.

Vermeil is a step above standard gold plating in quality, and it's a great option — especially for people with metal sensitivities, since sterling silver is generally well tolerated. The trade-off is that it's more expensive to produce, and the gold layer, while thicker than standard plating, is still thinner than gold filled.

It's something I'm personally interested in exploring for RILLA in the future. For now, gold filled remains my material of choice for the durability it offers.

What About Sterling Silver?

Sterling silver is 92.5% pure silver, mixed with a small amount of other metals (usually copper) for strength. It's a beautiful, high-quality metal with its own distinct look — cooler-toned, classic, and timeless.

Unlike gold filled or plated pieces, sterling silver doesn't involve any layering. It's solid silver all the way through, which means it's extremely durable. The trade-off is that silver can tarnish over time when exposed to air and moisture — but the good news is that tarnish is surface-level and easy to remove with a soft cloth.

At RILLA, the rings in our current collection are crafted in sterling silver. It was the right choice for our first ring designs — solid, durable, and beautiful in its own right. As we expand the ring collection, we'll be offering gold options as well.

The Bottom Line

If you want jewelry you can actually live in — shower in, sweat in, sleep in — gold filled is your answer. It's not a compromise. It's a smart choice.

That's why every RILLA piece (outside of our sterling silver rings) is made with gold filled metals. Because beautiful jewelry should be for living, not just for looking at.
