How to Know If Your Jewellery Is Good Quality — 7 Things to Check Before You Buy

Most people have bought a piece of jewellery that looked beautiful in the photo, arrived looking perfect — and within weeks started to tarnish, discolour, or fall apart. It's frustrating. And it's almost always avoidable, once you know what to look for.

After years in the jewellery industry, we've learned that quality isn't always obvious at first glance — but there are clear, reliable signals that separate a piece built to last from one that won't make it past summer. Here are the 7 things every smart buyer should check before they purchase.

1.  The Base Metal

The base metal is the foundation everything else is built on — and it's the single most important quality indicator in any piece of jewellery. The finish might look identical, but what's underneath determines how long it lasts, how it feels on your skin, and whether it will tarnish or cause reactions.

The hierarchy runs like this: surgical-grade stainless steel (316L) and solid gold are the gold standard for everyday wear. Sterling silver is decent but requires maintenance. Brass and copper bases are the lowest tier — and the most likely to cause green skin and rapid tarnishing.

Always ask: what is the base metal? If a brand won't tell you — or uses vague terms like 'premium alloy' — that's a red flag worth paying attention to.

2.  Plating Thickness & Type

For gold plated jewellery, the thickness of the plating directly determines how long the gold finish lasts. Plating is measured in microns — and the difference between a 0.5 micron flash plate and a 2.5 micron plate is the difference between a piece that fades in weeks and one that lasts years.

Industry standard for quality gold plated jewellery is a minimum of 1–2.5 microns. Anything below 1 micron is considered flash plating — it looks great in the photograph but won't survive real life. PVD (Physical Vapour Deposition) plating is the most durable option available, offering superior scratch and fade resistance over traditional electroplating.

3.  The Weight and Feel

Quality jewellery has substance. When you hold a well-made piece, it has a satisfying weight that cheap jewellery simply can't replicate. This is one of the most immediate and reliable quality indicators — and one you can feel the moment it arrives.

Lightweight pieces that feel hollow or plasticky are almost always made from low-grade alloys with thin walls. A quality stainless steel piece will feel solid, balanced, and substantial in your hand. That weight is the metal — and it tells you everything.

4.  Clasp and Fastening Quality

The clasp is where most jewellery fails first. A beautiful chain means nothing if the lobster clasp is flimsy, stiff, or poorly finished — it will either break or become impossible to open and close after a few weeks of wear.

Quality clasps should open and close smoothly with a satisfying click, feel sturdy between your fingers, and be made from the same quality metal as the rest of the piece. For earrings, butterfly backs should grip firmly without being painful to remove. Huggie hinges should snap cleanly shut and stay that way.

5.  Finish and Polish

The finish of a piece of jewellery is where craftsmanship becomes visible. A quality piece will have a consistent, even surface — whether that's a high mirror polish, a brushed matte, or a hammered texture. There should be no rough edges, no uneven plating, no bubbling or pitting on the surface.

Look closely at the inside of rings, the backs of pendants, and the joins of chains — these are the areas where shortcuts are most likely to show. Smooth, clean joins and evenly finished surfaces throughout are the mark of a piece made with genuine care.

6.  Skin Safety — Nickel-Free and Hypoallergenic

An estimated 10–15% of women have a nickel allergy — meaning nickel-containing jewellery causes redness, itching, and irritation on contact. Even if you don't currently have a reaction, repeated exposure to nickel can develop into a sensitivity over time.

Quality jewellery should be skin-safe for everyday wear. Stainless steel is one of the best choices for sensitive skin because it is inherently resistant to corrosion and unlikely to cause reactions. If you have sensitive skin, always look for pieces described as nickel-free or hypoallergenic.

7.  Brand Transparency

Perhaps the most overlooked quality signal of all — and the one that tells you everything. A brand that makes quality jewellery will be proud to tell you exactly what it's made from. They'll list the base metal, the plating type, the care instructions, and the materials clearly on every product page.

Vague descriptions like 'premium metal', 'high quality alloy', or 'gold tone' without specifics are almost always hiding something. The more clearly a brand communicates about their materials, the more confidence you can have in what you're buying. Transparency is the hallmark of a brand that stands behind its product.

Frequently asked questions

How can I tell if jewellery is good quality just from photos?

Look beyond the main product shot. Check for lifestyle photos, customer review images, and close-up detail shots. Look for consistent finish, clean joins, and even plating. Most importantly, read the full product description — quality brands will always communicate their materials clearly.

Is gold plated jewellery worth buying?

Absolutely — if the base metal is right. Gold plated stainless steel offers the look of solid gold at a fraction of the price, with exceptional durability. Gold plated brass or copper is a different story — the base will eventually show through and react with your skin. Always check what's underneath the gold.

What is PVD plating and why does it matter?

PVD (Physical Vapour Deposition) is the most advanced plating technique available for fashion jewellery. It creates a bond between the gold and the base metal at a molecular level, making it significantly more resistant to scratching, fading, and tarnishing than traditional electroplating. It's the reason PVD-plated pieces last years rather than months.

How long should good quality gold plated jewellery last?

With a quality base metal (stainless steel), proper plating thickness, and PVD coating, a well-made gold plated piece should maintain its finish for 2–5 years of daily wear — and significantly longer with occasional wear. Pieces with thin flash plating over brass bases may show wear within weeks.

Does price always indicate quality in jewellery?

Not at all. Many expensive fashion jewellery brands use brass bases with thin plating and charge more for branding. Mid-price brands using stainless steel bases with quality plating will far outlast pieces costing three times as much. Know your materials — price is the least reliable quality indicator.
