Picture this: you are out shopping, and you stumble upon a gorgeous piece of jewellery that seems almost too good to be true. The price is right, and it has all the sparkle and shine you could ever want. But hold up: how can you tell if it is the real deal or a total fake? In this guide, we walk through some easy ways to spot counterfeit jewellery and make sure you are always rocking the genuine article.
What does "Fake Jewellery" Mean?
First things first, let us define what we mean by "fake jewellery." Essentially, it is any piece of jewellery that is not what it claims to be. This could mean it is made from cheaper materials than advertised, or it is a knockoff of a designer brand. Fake jewellery can range from low-quality costume pieces to convincing counterfeits that are hard to distinguish from the real thing.
Common Signs of Fake Jewellery
So, how can you tell if that sparkly new necklace or bracelet is a phony? Here are some common signs to look out for.
Weight
Genuine precious metals like gold and silver are heavier than their counterfeit counterparts. If a piece feels suspiciously light, it could be a fake.
Markings
Real jewellery often has hallmarks or stamps indicating the metal content and manufacturer. The "925" stamp, for example, indicates sterling silver at 92.5% pure silver. For a complete reference on the 925 mark and other hallmarks, see our guide on what does 925 mean on jewellery. If hallmarks are missing or look sketchy, that is a red flag.
Magnet test
Most precious metals are not magnetic, so if a piece is strongly attracted to a magnet, it is likely a fake.
Skin reaction
Some fake jewellery can cause skin irritation or discolouration due to the presence of nickel or other cheap metals. If you notice any redness or itching after wearing a piece, it might not be the real deal.
Easy Ways to Spot Fake Jewellery
Now that we know some common signs of counterfeit jewellery, let us dive into some easy tests you can do at home to separate the real from the fake.
The acid test
This one is a bit more advanced, but you can buy gold and silver testing kits that use a small amount of acid to determine the purity of the metal. If the jewellery does not pass the test, it is probably a fake.
The sound test
Gently tap the piece of jewellery against a hard surface. Real gold and silver will make a high-pitched ringing sound, while fakes will sound duller and more muted.

Tips for Spotting Fake Jewellery When Shopping
If you are out shopping for jewellery, there are a few extra things to keep in mind to avoid getting duped.
Do your research
If you are looking at designer pieces, familiarise yourself with the brand's signature styles, materials and markings. That way, you will be better equipped to spot a fake.
Check the price
If a deal seems too good to be true, it probably is. Be wary of prices that are significantly lower than what you would expect for a genuine piece.
Look at the details
Genuine jewellery often has a higher level of craftsmanship and attention to detail than counterfeits. Look closely at things like clasps, prongs and stones to see if they appear well-made and securely attached.
Trust your instincts
If something feels off about a piece of jewellery, trust your gut. It is better to err on the side of caution than to end up with a fake.
Authentication by Material Type
Not all jewellery is created equal, and different materials have their own authentication considerations. Here is a guide to where to learn more about authenticating specific types of jewellery and components.
Sterling silver
Sterling silver authentication is one of the most common questions buyers face, particularly given how widespread imitation silver has become. For a complete authentication guide including the magnet test, weight test, nitric acid test and hallmark inspection, see our flagship guide on how to tell if sterling silver is real.
Swarovski crystals
Counterfeit Swarovski crystals are widespread, particularly in the bead and pendant market. Genuine Swarovski crystals from 1989 onwards carry a laser-engraved Swarovski logo, and the precision-cut consistency is impossible to fake at scale. For a detailed Swarovski-specific authentication guide, see our flagship on how to tell if Swarovski crystals are genuine.
Crystals and gemstones
For natural crystals and gemstones, authentication involves visual inspection, hardness tests using the Mohs scale, and tools like jeweller's loupes and refractometers. See our complete guide on how to identify crystals for the full method.
Diamonds
Real diamonds are incredibly hard and have a high level of brilliance and fire. If a stone seems dull or scratches easily, it might be a fake. You can also use a loupe or magnifying glass to look for imperfections that would not be present in a genuine diamond.
Pearls
Real pearls are cool to the touch and have a slightly gritty texture when rubbed gently against your teeth, while fake pearls tend to feel smooth and glassy. The weight, lustre and surface temperature of a real pearl are all distinctive markers when handled.
Vintage jewellery
Authenticating vintage pieces can be tricky, as they may not have modern hallmarks or stamps. In this case, it is best to work with a reputable dealer or appraiser who has experience with antique jewellery.
Final Thoughts
At the end of the day, the best way to avoid fake jewellery is to do your research and buy from trusted sources. Look for reputable dealers with a proven track record of selling genuine pieces, and do not be afraid to ask questions or request authentication documents.
Investing in high-quality, genuine jewellery is always worth it in the long run. Not only will you have a piece that you can cherish for years to come, but you will also be supporting the artisans and designers who put their heart and soul into creating these beautiful works of art.
FAQs
How do I tell if jewellery is real or fake?
Seven simple tests: 1) Check for hallmarks (925, 750, 14K, 18K). 2) Strong magnet test — real silver and gold are not magnetic. 3) Acid test for gold (specialist kit). 4) Weight — real precious metals feel heavier than plated. 5) Skin test — fakes often turn skin green/black. 6) Visible wear patterns. 7) Polishing cloth — Sterling Silver leaves black residue.
How can I tell if gold jewellery is real?
Five gold tests: 1) Look for hallmarks (750 = 18K, 585 = 14K, 375 = 9K). 2) Magnet test — real gold is not magnetic. 3) Acid test using a gold testing kit (£15–£30). 4) Ceramic plate test — real gold leaves a gold streak, fake leaves black. 5) Density and weight — real gold is significantly heavier than gold-plated alternatives.
What's the difference between gold-plated and solid gold?
Solid gold is gold alloyed with other metals throughout (9K, 14K, 18K, 22K, 24K). Gold-plated has a thin gold layer (typically under 0.5 microns) chemically bonded over base metal — wears through in 1–3 years. Gold-filled has a thick gold layer (5% of total weight, regulated standard 1/20 14K) mechanically bonded — lasts decades. Solid gold and gold-filled retain value; plated wears off.
How do I spot fake Sterling Silver?
Three tests confirm or expose fake 925 silver: 1) Look for the 925 hallmark — fakes often lack any stamp or carry questionable marks. 2) Strong magnet test — real Sterling Silver is not magnetic. 3) Polishing cloth test — Sterling Silver leaves a black tarnish residue on a soft white cloth; many fakes don't. Sterling Silver also feels heavier and cooler than plated alternatives.
Can I tell fake jewellery by skin reaction?
Yes — skin discoloration is a strong fake indicator. Real Sterling Silver, gold-filled and surgical stainless steel rarely cause skin reactions. Fake or low-quality plated jewellery typically turns skin green (copper base reaction) or black (silver compound reaction) within hours of wear. Sweat, perfume and hand sanitiser accelerate these reactions on plated and base-metal fakes.
Where is the safest place to buy real jewellery?
Buy from established jewellers, authorised brand partners or reputable online retailers with verifiable trading history. For Swarovski crystals and crystal jewellery components, buy from an Authorised Swarovski Distribution Partner like Bluestreak Crystals which sources direct from Wattens, Austria. Avoid heavily discounted listings on social media flash sales — these are the most common source of fake jewellery.
