Gold-plated jewelry has a genuinely thin layer of real gold—usually 0.5 to 2.5 microns thick—electroplated onto a base metal underneath. The Flaire's pieces use 18K gold plating (75% pure gold) bonded over 316L stainless steel, so the gold you see and touch is real, even though the total gold content by weight is small. What actually determines how good a piece looks and how long it lasts is the karat purity, the micron thickness, and the quality of the base metal it's plated over.

What "18K Gold Plated" Actually Means

The karat number describes the purity of the gold in the plating layer, not how much of it there is. 18K gold is 75% pure gold mixed with other metals for durability, the same purity used in fine solid-gold jewelry. "Gold plated" describes the process: a thin layer of that 18K gold is electroplated onto a base metal, most commonly brass, copper, or 316L stainless steel. The Flaire plates over 316L stainless steel specifically because it doesn't corrode or discolor the way brass and copper can once the gold layer wears thin.

How Thick Is the Gold Layer? (Microns Explained)

Thickness is measured in microns (one micron = one-thousandth of a millimeter). Most gold-plated fashion jewelry falls between 0.05 and 0.5 microns—thin enough to fade within months of regular wear. Heavier plating in the 1 to 2.5 micron range holds its color and shine far longer because there's simply more gold standing between your skin, water, and the base metal underneath. When you're comparing gold-plated pieces, ask about micron thickness, not just the word "plated"—that single number is the biggest predictor of how long a piece will actually look good.

Gold-Plated vs Gold Vermeil vs Gold-Filled vs Solid Gold

These four terms get used interchangeably online, but they describe very different amounts of actual gold:

Gold Plated

A thin electroplated layer of gold (typically under 2.5 microns) over any base metal. Most affordable, least gold by weight.

Gold Vermeil

Gold plating, but with two legal requirements in the US: the base metal must be sterling silver, and the plating must be at least 2.5 microns thick. More gold and a nicer base metal than standard plating, but usually pricier.

Gold-Filled

A much thicker layer of gold (5% of total weight, mechanically bonded rather than electroplated) over a base metal. More gold than plating or vermeil, but still not solid.

Solid Gold

Gold all the way through. The most gold by weight, and the most expensive by a wide margin—an 18K gold Cuban chain in solid gold can cost 20-50x what the same design costs gold plated.

Why the Base Metal Matters as Much as the Gold

A thicker gold layer only helps if what's underneath it doesn't undermine it. Brass and copper base metals oxidize, and that oxidation can bleed through thin plating, dulling the color or causing green discoloration on skin. The Flaire plates its 18K gold over 316L surgical-grade stainless steel, the same alloy used in medical implants, because it's naturally hypoallergenic, doesn't rust, and stays stable in water and sweat. That combination—18K gold plating over 316L stainless steel—is why pieces like the Lorenzo Chain and the Luxor Set are built to be worn daily, including in the shower and pool, without the base metal working against the gold layer.

How to Make the Gold Layer Last

Since the gold layer is finite no matter how many microns thick it is, care extends the life of any plated piece: avoid direct contact with perfumes, chlorine, and abrasive cleaners; store pieces separately so they don't scratch against each other; and wipe them down with a soft cloth after wear. With 18K gold plating over 316L stainless steel and reasonable care, pieces from The Flaire's chains and necklaces collection are backed by a 1-year warranty and a 30-day return window, so you're covered if plating quality is ever in question.

Frequently Asked Questions

Is 18K gold plated jewelry real gold?

Yes. The plating layer itself is 75% pure gold (18 karat), the same purity as solid 18K gold jewelry. What's different is the amount of gold present, not its purity—plating is a thin layer rather than gold all the way through.

How much gold, by weight, is on a gold-plated chain?

It varies by micron thickness and piece size, but for a typical plated chain the gold layer weighs a small fraction of a gram—often less than 0.05 grams total. The value of plated jewelry comes from the design and craftsmanship, not gold weight, which is why it's priced far below solid gold.

Does more microns always mean better quality?

Generally yes for longevity—more microns means more gold standing between the base metal and the outside world, so color holds longer. But the base metal matters too: 1 micron of 18K gold over 316L stainless steel will typically outlast 2 microns over untreated brass.

Will gold-plated jewelry look identical to solid gold?

Visually, yes—the gold layer is the only part you see, so a well-plated piece looks identical to solid gold on day one. The difference shows up over time and in price, not in initial appearance.
