Short answer: solid gold is gold all the way through. Gold filled and vermeil have a real layer of gold with a legal minimum thickness. Gold plated is a thinner coating that wears with time. "Gold bonded" has no legal definition at all, so it means whatever the seller says it means. At Olivia Star it means a small piece of real 14K gold heat-bonded onto sterling silver, and we print the weight of that gold on every product page. Below is what each term means, how much gold you actually get, and how to choose.
The side by side
| What it is | How much gold | How long the gold lasts | Price level | |
|---|---|---|---|---|
| Solid gold | The whole piece is gold alloy, for example 14K | All of it: 14K is 58.3% pure gold | For life; it can scratch but never wears through | Highest |
| Gold filled | A thick layer of gold pressed onto a base metal, usually brass | At least 1/20 of the weight | Many years with normal care | Middle |
| Vermeil | Sterling silver coated with gold | At least 2.5 microns of 10K or finer gold | Years, depending on wear | Middle |
| Gold plated | A thin coating of gold over a base metal | A thin layer; thickness varies by maker | Months to a few years, depending on wear | Lower |
| Gold bonded at Olivia Star | A piece of real 14K gold heat-bonded onto sterling silver, with silver visible | 0.02 to 0.56 g of 14K gold per piece, listed on each product page | The gold part is solid 14K, not a coating | Lower to middle |
The legal definitions in this guide come from the US Federal Trade Commission's Jewelry Guides, the rules American sellers have to follow when they describe precious metals.
First, what 10K, 14K and 18K mean
Pure gold is 24 karat. It is too soft for jewelry you wear every day, so it is mixed with other metals. The karat number tells you how much of the mix is gold:
- 10K: 41.7% gold. The legal minimum to be called gold in the US.
- 14K: 58.3% gold, stamped 14K or 585. The most common choice for everyday jewelry in the US, because it is harder than 18K and keeps its shape.
- 18K: 75% gold, stamped 18K or 750. A deeper yellow, but softer and easier to scratch.
All the gold on Olivia Star pieces is 14K, whether it is bonded or plated.
Solid gold
The whole piece is made of gold alloy. Nothing can wear through, because there is nothing underneath. It is also the most expensive option by far, because you pay for the weight of gold. At the October 2026 gold price of about $4,100 an ounce, a plain 14K band weighing 2.5 grams contains roughly $190 of gold before any design, labor or store margin. Heavier pieces scale up quickly.
Gold filled
A thick sheet of gold alloy is bonded to a base metal with heat and pressure. To be sold as gold filled in the US, the gold has to be at least 1/20 of the total weight of the metal and at least 10K. That is far more gold than plating, so gold filled holds its color for many years. The catch is the base: it is usually brass, and if the gold layer is ever worn or cut through, brass is what you see.
Vermeil
Vermeil (say "ver-may") has a strict legal meaning: sterling silver coated with gold of at least 10K, at least 2.5 microns thick. Think of it as heavy plating over silver instead of over brass. If a seller calls a piece vermeil and the base is not sterling silver, or the gold is thinner than 2.5 microns, it is not vermeil.
Gold plated
A thin coating of gold over a base metal, applied by electroplating. The FTC asks that plated gold be of "reasonable durability" and at least 10K, and it sets separate minimums for terms like gold electroplate (0.175 microns) and heavy gold electroplate (2.5 microns). In practice, thickness varies a lot between makers, and the base metal matters just as much: plating over brass can show a darker metal or leave a green mark once it wears, while plating over sterling silver wears to silver.
Our gold plated pieces are 925 sterling silver under a real 14K gold finish. They are gold color all over, posts and backs included, and each product page lists the weight of the silver inside. We do not call them vermeil: vermeil needs a verified minimum thickness, and we only use terms we can stand behind for every piece.
Gold bonded: what it means at Olivia Star
There is no legal definition of "gold bonded", and brands use it for very different things. Some use it for ordinary plating with a nicer name. So here is exactly what it means on our site:
- The gold is a piece of real 14K gold (585), not a coating. It is heat-bonded onto the silver as a plate, a bar or an inlay.
- You can see both metals. Part of the piece is gold, and part is sterling silver. The silver is rhodium-plated, which keeps it bright and slows tarnish.
- The gold weight is on every product page. Across our bonded pieces it runs from 0.02 to 0.56 grams of 14K gold, most often around 0.09 grams.
Because the gold part is solid 14K rather than a few microns of coating, it does not wear through to a different metal the way plating can. It is also why our bonded pieces cost far less than solid gold: most of the piece is sterling silver, and you pay for the gold you can see, not for gold hidden inside.
How long does each one last?
- Solid gold: for life. It scratches and can be polished again.
- Gold filled: often many years, even worn daily, as long as the layer is not cut through.
- Vermeil: years with care; rings and bracelets wear faster than earrings and pendants because they rub more.
- Gold plated: anywhere from months to a few years. Rings worn every day wear fastest. Earrings and pendants last much longer.
- Gold bonded at Olivia Star: the gold part is solid 14K, so it keeps its color the way solid gold does. The silver part may darken slowly over time like any silver and comes back with a polishing cloth.
How to make gold jewelry last
- Put jewelry on last: after lotion, perfume and hairspray.
- Take it off for the shower, the pool, the beach and the gym. Chlorine and salt are hard on plating and on silver.
- Wipe it with a soft cloth after wearing, and store pieces separately so they do not scratch each other.
- Do not use silver dip or abrasive polish on gold plated pieces: it can strip the gold.
How to tell what you are buying
- Read the stamp. Solid gold is stamped with its karat (10K, 14K, 585, 18K, 750). Gold filled is often stamped GF or 1/20 14K GF. Sterling silver is stamped 925. A piece stamped only 14K with no other mark should be solid gold.
- Look for the base metal. "Gold plated" alone does not tell you what is underneath. Sterling silver underneath is better than brass, because worn plating then shows silver, not a darker metal.
- Check the price against the gold. Gold costs about $77 per gram of 14K alloy at October 2026 prices. A "solid 14K" ring that weighs 3 grams and costs $60 cannot be solid gold.
- Ask what "bonded" means. Since it has no legal definition, ask how much gold the piece contains. We answer that on every product page.
Which one should you choose?
- You want it to last for decades, or to pass down: solid gold.
- You want all-gold color for daily wear on a budget: gold filled or vermeil, or gold plated earrings and pendants, which wear slowly.
- You want real gold that will not wear off, and you like silver and gold together: gold bonded, like our gold and silver rings, gold and silver earrings and pendants.
- You want an all-gold look at a lower price and do not mind gentle care: gold plated over sterling silver, like our 14K gold plated rings and 14K gold plated earrings.
Questions we get
Is gold bonded the same as gold filled?
No. Gold filled is a legal term with a minimum of 1/20 gold by weight over the whole piece. Gold bonded has no legal definition. On our pieces it means solid 14K gold on part of the piece, with the exact gold weight listed.
Is gold plated real gold?
The coating is real gold, usually 10K to 24K. Ours is 14K. The piece itself is mostly the base metal underneath, which is sterling silver on ours.
Will gold plated jewelry turn my finger green?
Green marks usually come from a brass or copper base showing through worn plating. Under our gold is 925 sterling silver with no nickel. Silver can occasionally leave a faint gray mark on some skin, which washes off with soap.
Can I shower with gold plated or gold bonded jewelry?
We recommend taking both off. Water alone will not ruin them, but soap, shampoo and chlorine wear plating faster and dull silver.
Is 18K better than 14K?
18K has more gold and a deeper color; 14K is harder and holds up better to daily wear. For rings worn every day, many jewelers recommend 14K.
See the difference
Every gold piece we sell uses real 14K gold over 925 sterling silver, and the product page tells you which kind it is: bonded, with the gold weight listed, or plated, gold all over. US shipping is free on every order, and unworn pieces can be returned free within 30 days.
