How to Tell if Your Ring Is Real Gold

If you're trying to figure out if a ring is the real deal, your first port of call should always be the inside of the band. You're looking for a tiny little stamp; the hallmark. It's basically the ring's passport.

If you see a "375," you've got 9ct gold, whereas "750" means it's 18ct. These aren't just random numbers; they're a legal guarantee from places like the Assay Office here in the UK, making sure you aren't being sold a pup when it comes to purity.

You can usually spot the difference between solid gold and a plating job just by looking for a bit of wear and tear. Real gold doesn't do "costume jewellery" things — it won't peel or show a silverish metal underneath after a few months of wear. It stays the same colour through and through.

So, if you've got a ring that feels a bit "plasticky" or is starting to discolour, it's a red flag. When in doubt, having a professional look at it is your best bet.

Understanding Gold Ring Purity: 9ct, 14ct, 18ct and 22ct

In the workshop, we rarely work with pure gold because it's just too temperamental for most designs. To give a piece any kind of longevity, we blend it with different metals to create a sturdy alloy. We use the carat scale to tell the story of that purity.

Choosing the right gold is basically a balancing act between "toughness" and that gorgeous, deep glow. 9ct is your workhorse; it's got more alloy in it, so it can take a bit of a battering in daily life, though it's a paler yellow.

If you want something that looks a bit more "luxe" but won't scratch, 14ct is a brilliant middle ground. 18ct is where things get serious; it's got that rich, buttery colour we all love, but because it's purer, you've got to be a tiny bit more careful with it.

How to Choose the Right Size for Your Finger

Choosing a ring in gold is an investment, so it's worth being a bit fussy about the size. You want it to feel like it's barely there, rather than something you're constantly fiddling with.

1. Measure with stringWrap a piece of string around the base of your finger to find the circumference.
2. Get the millimetresLay the string flat and note the exact measurement — accuracy here is everything.
3. Convert on a UK chartTake that number to a standard UK sizing chart. It'll translate into the letter system we use.
4. Factor in the weightConsider adding half a size if you're going for a substantial piece — a heavy gold band sits more restrictively than a delicate one.
5. Mind the weatherIt sounds silly, but a hot day can change your ring size quite a bit. Aim for a neutral environment to get the most honest reading.

Most solid gold rings can be adjusted later if life changes, but try to get the "sweet spot" now so you can wear it straight away.

How to Clean Gold Rings Without Damaging Them

The simplest way to clean gold rings is with warm water, mild soap, and a soft brush. It's easy to forget that gold jewellery needs a bit of a scrub every now and then. All that daily wear can leave things looking a bit dull, particularly if there are stones involved.

A quick ten-minute dip in warm, soapy water usually does the trick. We always suggest using a soft toothbrush to get into those awkward little gaps where dirt likes to hide. Just a quick rinse and a dry with a soft cloth, and you're sorted.

White Gold Rings

There's no denying that white gold rings for women look stunning, but that rhodium coating is actually quite delicate. If you're cleaning it at home, less is definitely more. Avoid the tempted-to-scrub approach and definitely keep it away from household cleaners. A gentle soak is all it needs to stay bright.

Gold Diamond Rings

You've got to keep an eye on your diamonds, as they're notorious for attracting grease and losing their sparkle. A bit of a regular "wash and brush up" makes a world of difference. Whether it's an eternity gold ring or a simple gold band, the trick is to avoid anything too abrasive.

White Gold Diamond Rings

The best way is to use a really soft brush — an old toothbrush works wonders — to gently get into the nooks and crannies. It's the easiest way to bring back that "new" shine without risking any damage to the setting itself.

If you treat your pieces with a bit of respect and follow some solid expert advice, they'll stay brilliant for a lifetime. It's all about those small habits, really.

Will Gold Plated Rings Tarnish?

Yes. We often get asked if plating is worth it, and honestly, it depends on how much you love the piece. Plating is essentially a "gold-coloured" coat that's going to thin out with every wash and rub. Before you know it, the ring looks a bit tired and dull.

That's why we always say if you're planning on wearing it every day — like a gold eternity ring — solid gold is the only way to go. It won't peel or change colour on you; it's just gold all the way through, which saves a lot of heartbreak later on.

How Much Are Gold Rings Worth?

When you're shopping for gold, the price tag is basically a mix of weight, purity, and the time a jeweller spent at their bench. A 14ct ring is a great "entry" point, often costing between £400 and £800 — sometimes more due to gemstones and diamonds — whereas 18ct feels a bit more substantial and carries a price to match, usually £600 plus.

How much is a 22ct gold wedding ring worth?

If you've got your heart set on a 22ct wedding ring, keep in mind that since it's almost pure gold, it's quite sensitive to the daily market price. You're likely looking at a starting point of about £800, heading north depending on how chunky the design is.

9ct vs 18ct Gold: Which Is Right for You?

Choosing your gold is a bit of a balancing act. 9ct is a practical, no-nonsense choice; it's durable, hard-wearing, and a great entry point if you're being mindful of spending. The trade-off is that it's a bit lighter in colour and doesn't have quite the same "precious" feel.

18ct is where you really see the difference; that extra gold gives it a depth of colour that's hard to beat. It's an investment, certainly, but it's the kind of quality that ages gracefully. If you're after a bit of everyday luxury that keeps its value, 18ct is almost always the way to go.

Gold Rings for Women: Trends & Popular Designs

We've always thought a ring tells you a lot about a person. These days, white gold rings for women are the ultimate for that clean, diamond-heavy look, but then you've got the rose gold ring, which feels a lot more distinctive and romantic.

If you want something with a bit of history, the gold signet ring is definitely the one to watch this year. If you're marking an anniversary, a white gold eternity ring is usually the top pick for that "wow" factor.

The best part? There are no rules anymore; people are just stacking them up and making it up as they go, which is exactly how jewellery should be.

Everything Else Worth Knowing

What carat should a gold ring be?

We usually suggest 14ct or 18ct. It's just more practical. You get that lovely weight and colour, but it's hardy enough to wear every single day without worry.

How do I know what carat my gold is?

Just check the inside of the band for a tiny engraved number. 375, 585, and 750 are the ones to look out for. If it's not there, it might not be solid gold.

Does wearing gold help with menopause?

Not as far as the experts are concerned. Gold is brilliant for a confidence boost, but it's not a medical treatment, unfortunately.

How much is a gold ring worth?

Price depends on how much gold is actually in the piece. Most gold rings start around £150, but a proper solid gold statement piece can easily hit the £1,500 mark.
