Gold-plated, gold vermeil, gold-filled, solid gold: what's the difference? These terms appear on almost every jewellery website, and they can make a big difference to price, durability and care. Here's a clear, honest guide to what each one means, so you can choose with confidence.
Solid gold
Solid gold jewellery is gold all the way through, mixed with other metals for strength. The purity is measured in karats:
- 9K: 37.5% gold, often stamped "375"; very common in Australia.
- 14K: 58.5% gold, stamped "585".
- 18K: 75% gold, stamped "750".
- 24K: close to pure gold, but very soft for everyday jewellery.
Best for: heirloom pieces and jewellery you never take off. It's the most durable option, and also the most expensive.
Gold-filled
Gold-filled jewellery has a thick layer of solid gold mechanically bonded to a base metal, usually brass. In the US, it must contain at least 5% gold by weight. The gold layer is much thicker than plating, so it lasts longer.
Best for: everyday chains and earrings that you want to last for years, at a price between plated and solid gold.
Gold vermeil
Gold vermeil (pronounced "ver-may") is sterling silver coated with a layer of gold. In the US, vermeil must have a 925 sterling silver base and a gold layer of at least 2.5 microns. Australia has no specific legal standard for the term, so it's worth checking the details a brand provides.
Best for: people who want a precious-metal base with a gold look.
Gold-plated
Gold-plated jewellery has a thin layer of gold applied over a base metal such as brass, copper or sterling silver. It offers the look of gold at an accessible price and makes it easy to enjoy trend-led designs.
Because the layer is thinner, plating can gradually fade with wear, friction, water, perfume and sweat. With good care, it can still look beautiful for a long time. Read do gold-plated earrings tarnish? and are gold-plated earrings good?
Best for: fashion pieces, statement designs and gifts.
Quick comparison
| Base | Gold layer | Durability | Price | |
|---|---|---|---|---|
| Solid gold | Gold alloy throughout | Not a layer | Highest | $$$$ |
| Gold-filled | Usually brass | Thick, bonded | High | $$$ |
| Gold vermeil | Sterling silver | Thicker plating | Medium–high | $$–$$$ |
| Gold-plated | Brass, copper or silver | Thin plating | Varies with care | $–$$ |
What about "K-gold plated" or "18K gold plated"?
These phrases describe the colour and purity of the plating layer, not the whole piece. "18K gold-plated" means the thin surface layer is 18K gold; underneath is a different metal. It is not the same as solid 18K gold.
What about sensitive ears?
For earrings, the part that matters most is the post that goes through your ear. Many people with sensitive ears prefer posts made from 925 sterling silver, titanium or solid gold. Always check the post material listed on the product page. Our 925 sterling silver earrings guide explains what to look for.
What Lyastone jewellery is made of
We believe in being clear about materials. Most Lyastone pieces are gold-plated or silver-tone plated over brass or copper, which lets us offer meaningful designs at an accessible price. Some pieces use 925 sterling silver, and many of our earrings have 925 sterling silver posts. Every product page lists the exact base metal, finish and post material, so you always know what you're buying.
How to make gold-plated jewellery last longer
- Last on, first off: put jewellery on after perfume, lotion and make-up, and take it off before sleeping.
- Keep it dry: remove it before showering, swimming and exercising. See can you swim in gold-plated jewellery?
- Wipe gently: use a soft, dry cloth after wearing. Avoid polishing cloths with chemicals and abrasive cleaners.
- Store separately: in a pouch or jewellery roll, away from humidity and other pieces that could scratch it.
The bottom line
There's no single "best" option, only the best option for you. Choose solid gold for forever pieces, gold-filled or vermeil for long-lasting everyday wear, and gold-plated for accessible, beautiful designs you can enjoy and change with your style. Whatever you choose, knowing the difference means no surprises.
