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.
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.
Our 14K gold filled collection includes the Sirius Solitaire Necklace in 14K Gold Filled and the Olympe Oval Engagement Ring.
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 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.

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.
