Quick answer
Solid gold is gold alloy all the way through. Gold filled is a thick layer of real gold bonded to a base metal with heat and pressure, making up at least 5% of the piece's total weight. Gold plated is a very thin layer of gold applied by electroplating. All three look the same on day one. They tell very different stories after months of daily wear.
Here is how each one is made, how it wears and which one makes sense for the piece you're buying.
Key takeaways
- Solid gold never wears off and costs the most. 14K is 58.3% gold.
- Gold filled bonds a thick gold layer, at least 1/20 of the weight, and stands up to daily wear.
- Gold plated is a thin electroplated layer, best for earrings and occasional pieces.
- Decide with one question: how often will it touch your skin?
Solid gold
Solid gold jewelry is gold alloy throughout. Cut it in half and it is the same metal inside and out.
Pure gold is too soft for most jewelry, so it gets mixed with other metals for strength. The karat tells you how much of it is gold, in parts out of 24. 14K gold is 58.3% gold, the rest being other metals that make it harder and more wearable.
- Pros: nothing to wear off, ever. Can be polished and resized.
- Cons: the most expensive option by a wide margin, especially for chunkier pieces.
- Best for: heirloom pieces and anything you plan to wear for decades.
Gold filled
Gold filled jewelry has a solid layer of gold bonded to a base metal using heat and pressure. It isn't a coating. It is a real, thick sheet of gold fused to the core.
To be called gold filled, the gold layer has to make up at least 5% of the total weight of the piece. That is why you'll see the stamp 1/20 14K GF: one twentieth of the weight is 14K gold.
- Pros: far more gold than plating, so it holds its color through daily wear. Much more affordable than solid gold.
- Cons: costs more than plated jewelry. Very heavy friction over a long time can still reach the core, and resizing isn't as simple as with solid gold.
- Best for: pieces you wear every day, like the necklace or ring you reach for every morning.

Gold plated
Gold plated jewelry has a very thin layer of gold applied to a base metal by electroplating. The piece sits in a solution, an electric current runs through it, and gold settles onto the surface.
What's underneath matters a lot. Cheap plated jewelry often sits on a base that can irritate skin once the gold wears. At Daellia, our gold plated pieces are 925 sterling silver plated with 18K or 14K gold. That means real silver under the gold, and no nickel or lead.
- Pros: the most affordable way to get a rich gold color. Great for trend pieces and statement looks.
- Cons: the layer is thin. Friction, water, sweat, lotion and perfume wear it down over time. How fast depends on how often you wear it and how you care for it.
- Best for: earrings, occasional pieces and styles you want to try without a big spend.
What the label has to mean
US rules set a floor. To be sold as gold filled, the gold layer must be at least 10K and at least 1/20 of the metal's weight. Gold electroplate only needs 0.175 microns of fine gold, and heavy gold electroplate 2.5 microns.

Which one should you buy?
Ask yourself one question: how often will this touch my skin?
- Every day, all day? Gold filled. It gives you the most wear for the money.
- A few times a week or less? Gold plated over sterling silver is a smart buy. Earrings get very little friction, so plating lasts longest on them. Browse our moissanite hoop earrings.
- Once in a lifetime? Solid gold, if the budget allows.
And if you prefer white metal, 925 sterling silver plated with rhodium gives a bright, cool finish that pairs cleanly with white moissanite.
How to make any gold finish last longer
- Put jewelry on last, after lotion, perfume and hairspray.
- Take it off before swimming, showering and the gym.
- Clean with warm water, a drop of mild dish soap and a soft toothbrush. Dry with a lint-free cloth.
- Skip harsh chemicals, and keep plated pieces out of ultrasonic cleaners.
- Store each piece separately so nothing rubs or scratches.

What about the stone?
The metal can wear. Moissanite won't. It doesn't cloud or fade, and at 9.25 on the Mohs scale it handles daily life well. So when you choose a piece, the metal is where your decision really matters. More on that in does moissanite get cloudy.

Shop 14K gold filledFrequently asked questions
What does 1/20 14K GF mean?
It means gold filled, with a layer of 14K gold that makes up one twentieth, or 5%, of the piece's total metal weight. GF stands for gold filled. Under US rules, a piece can only be sold as gold filled if its gold layer is at least 10K and at least 1/20 of the weight, so the stamp tells you something real.
Is gold vermeil the same as gold filled?
No. Vermeil is sterling silver plated with gold of at least 10K, at least 2.5 microns thick under US rules. That is heavier than standard plating, but it is still a plated layer. Gold filled uses a thick sheet of gold bonded with heat and pressure, making up at least 1/20 of the weight, which is why it suits pieces worn every day.
Can you shower with gold filled jewelry?
You can, but it is better not to. Water alone won't hurt gold filled, but soap, shampoo, chlorine and hot water leave films and speed up wear on any finish. Take pieces off to shower, swim or work out, and put them back on after lotion and perfume have dried. The gold keeps its glow longer.
Is gold filled jewelry good for sensitive skin?
It is often a good choice. Your skin touches a thick layer of real gold rather than a thin coat that wears through. Nickel is the most common contact allergy in industrialized countries, and every Daellia metal is nickel- and lead-free. If your skin is very reactive, keep pieces clean and dry, and take them off at night.
How long does gold plated jewelry last?
It depends on the thickness of the layer and how you wear it. US rules require only 0.175 microns for gold electroplate, so plating on rings and bracelets, which rub all day, shows wear first. Earrings get little friction and keep their color much longer. Put plated pieces on last, keep them dry and store them apart.
