10 Easy Ways to Know if Your Gold Jewellery Is Real!

Gold jewellery is not simply an accessory — it is a representation of beauty, tradition and even wealth. But how can you determine if the gold you own is real or fake? To safeguard your investment and appreciate its true value, we need do verify it’s authenticity. For that you don’t always require professional testing — there are many simple methods to check your gold’s authenticity at home.

  1. Check Hallmarks on Jewellery

The quickest way to tell if your gold is real is to look for hallmarks, these marks indicate the purity of the gold and often located on the inner bands of rings, clasps of chains, or back of pendants.

Hallmark purity is expressed in karats (K) or millesimal fineness.

  • 24K – 99.9% Pure gold
  • 22K – 91.6% gold
  • 18K – 75% gold
  • 14K – 58.3% gold
  • 10K – 41.7% gold

If your jewellery lacks a hallmark, then it may not be real gold. Some older pieces may not have these marks. So additional tests can assist in authenticity confirmation.

  1. Check Letter Markings on Jewellery

Other than hallmarks, pay attention to letter markings that suggest if your jewellery is pure gold, or just gold-plated.

Common markings of letters are: 

  • GP (Gold Plated) – Very thin layer electroplated on metal
  • GF (Gold Filled) – A heavier coating, but not solid.
  • GE (Gold Electroplated) – Electrolytic application of gold plating.
  • RGP (Rolled Gold Plate) – A gold-filled process where there is less gold.
  • HGP (Heavy Gold Plated) – A heavy coat of gold plating.

If you observe these markings, then your jewellery is gold plated.

  1. Water Test

Gold is a heavy metal and will sink in water. To perform this test: Fill a bowl with water. Carefully drop your jewellery into the water. Observe its movement: 

  • Actual gold will sink right away because it’s heavy. 
  • Fake gold or gold-plated items might only float or sink slowly.

But this test is not infallible, as some counterfeit pieces can also sink because of their weight. So it should be used in conjunction with other methods.

  1. Magnet Test

We know that pure gold is not magnetic, so if your jewellery is attracted to a magnet, it most likely contains other metals. Use a strong magnet (e.g.neodymium magnet) and hold it near your jewellery. If your jewellery sticks to the magnet, it’s probably fake. However, since some fake jewellery is made with non-magnetic metals, we can’t completely rely on magnetic tests to confirm the purity of gold.

  1. Skin Test

Have you ever noticed your skin turning green or black when you wear certain jewellery? Gold is nonreactive, so it doesn’t cause any skin irritation. To test: Wear your gold jewellery for a few hours. Check for any discoloration on your skin: Real gold does not leave any markings.

Imitation gold may leave green, blue or black marks due to oxidation of other metals like copper or nickel. This test is most effective for lower karat gold (10K–14K) because higher karat gold rarely causes skin reactions.

  1. Make-up Test

Apply a layer of liquid foundation on your skin and let it dry. Rub your gold jewellery against the dried makeup. If a black mark appears, your gold is likely genuine! No mark? It could be fake or gold-plated. This happens because real gold reacts slightly with certain cosmetics, creating a black mark.

  1. Vinegar Test

Another household item that can help determine the authenticity of gold is vinegar. Place your gold jewellery in a small bowl. Now add a few drops of white vinegar. Observe the reaction: Real gold will never tarnish!

And fake gold may turn green, black or some other color due to corrosion.

Gold does not corrode, so it remains unchanged in vinegar.

  1. Nitric Acid Test (Note: Handle with Care)

Gold does not react with Nitric Acid. If you have access to nitric acid, follow these steps:

Safety first, Always wear gloves and safety glasses to protect yourself.

Step 1: Place the gold jewellery on a flat stainless steel surface.

Step 2:Then add a very small amount of nitric acid to the jewellery.

Check the reaction:

No reaction? It’s likely real gold.

Green or milky reaction? The gold is fake. 

Warning: Nitric acid is highly corrosive and dangerous. So this test requires strict safety precautions.  It should be performed by professionals and not for home use.

  1. Ceramic Test

One quick way to test the authenticity of your gold, is with an unglazed ceramic tile.

Choose an unglazed ceramic tile (white with a flat surface).

Gently rub your jewellery against the tile.

A genuine gold piece will show a gold streak, and counterfeit gold will show a black or gray streak.

Caution: Rubbing too hard may scratch your jewellery!

  1.  Weight and Size Test

Gold is naturally dense and heavy, so real gold jewellery should feel more substantial than imitations of the same size. Use a known real gold piece for reference. Then, grab both items in hands and compare their weights and sizes. If your jewellery feels too light, it’s likely not pure gold.

Final Thoughts:

While these tests provide valuable information, they’re not foolproof. Some high-end fakes can even pass simple home tests. For absolute certainty, consult a professional jeweler for:

  • X-ray fluorescence (XRF) testing
  • Electronic gold testers
  • Fire assay (most accurate method)

By combining multiple tests, you can confidently determine whether your gold is real or fake.

Gold is timeless, a true investment that lasts forever. Now, with these simple tests, you can wear your gold with confidence knowing its authenticity!

Mixed Metal Tones: Moving Beyond Traditional Jewellery Uniformity
Most people pick one gold colour and stay with it. A yellow gold chain gets yellow gold bangles, and that has been the habit for years. Now more buyers want to try yellow, white and rose gold together. It can feel risky at first, but it is easier than it looks. This blog explains the three colours and simple ways to wear them together. Most people buy jewellery in one colour. If they have a yellow gold chain, they buy yellow gold bangles to go with it. That was the normal way for many years. These days, people are trying different colours together. Many customers at Jos Alukkas now ask for pieces that have more than one gold colour in them. Mixing gold colours may sound strange at first. Many people worry it will look messy or that they will get it wrong. But it is simpler than it sounds. When the colours are put together the right way, the jewellery looks more interesting, and you get more use out of what you own. In this blog, we will look at the three gold colours and some easy ways to wear them together. Why People Stuck to One Colour Earlier, gold meant yellow gold. Brides got yellow gold sets. Mothers gave yellow gold to their daughters. Nobody thought about other colours. Then white gold and rose gold came into shops. Young people started buying them for daily use. Slowly, people stopped worrying about matching everything. The Three Colours Yellow gold is the usual gold colour we all know. It looks rich, warm and is relatively a better choice for weddings and festivals. White gold resembles silver, but it is actually gold. It looks amazing when used in thin chains, earrings, and rings.  Rose gold has a light pink shade. It looks soft on the skin. It goes well with both sarees and western clothes. How to Wear Them Together It is not difficult. You can start with the jewellery you already have. Wear a white gold chain with a yellow gold pendant. Put on earrings of one color and a ring of another color. Buy one piece that already has two or three colours in it. If you are not sure, the last one is the best way to start. The designer has already done the mixing for you. For Different Occasions Wedding: The yellow gold chain can be retained by the bride while adding the rose gold or white gold earrings to the chain. The ensemble looks quite traditional, but with a slight modification to it. Office: A thin white gold chain with a tiny rose gold pendant is a good pick. It looks simple and goes with most work clothes. Onam or Vishu: Wear a few yellow gold bangles along with one rose gold bangle. It looks lovely with a kasavu saree. Easy Tips Keep the finish the same. If one piece is shiny, keep the others shiny. Do not wear too many heavy pieces together. Look in the mirror before you buy. If it looks good on you, it is right. Conclusion You do not have to choose only one gold colour. Yellow gold, white gold and rose gold all look good, and they look even better together. Each one has its own look, and when you wear them the right way, your jewellery starts to feel more like your own. Start small. Try two colours on your hand or in one set. See how it feels. When you become confident about yourself, you may try using three colors. There is no rigid formula here. If it suits you and makes you feel happy, it is the right color. Visit Jos Alukkas, look at the designs with mixed gold colours, and try a few on. Our team will be happy to help you pick what suits your style and your occasion.

Micro-Designs and Lightweight Jewellery: The Changing Face of Modern Luxury
What happens when luxury becomes smaller? It may sound like a contradiction. For years, grand jewellery has been associated with larger silhouettes, elaborate designs and a noticeable sense of opulence. Yet today, a tiny pendant, a fine ring or a pair of delicate earrings can feel just as luxurious. It is reflected in jewellery produced by Jos Alukkas, which combines good design, detailing, and lightweight forms that meet the contemporary taste and preferences. The catch is that modern luxury starts to conceal its allure in such areas that need a closer examination. It turns out that when one takes a closer look, he realizes that size is just the beginning of the story. Why Lightweight Jewellery Is Becoming More Popular Not only does micro-designing consist of a tendency towards miniature jewellery items, but there is a general change in the manner in which people approach luxury goods. They don’t keep their jewels anymore in order to have them used on a special occasion like marriage; rather, they prefer those jewels that can be worn as a daily wear jewel.  This is the reason behind the popularity of lightweight jewellery since it can be worn throughout the day along with different clothes. But in case of lesser metal and lesser designing space, the question is how something special can be designed within these constraints. The Detail Behind Micro-Designs Here lies the fascination with micro-designs. Shrinkage of a design doesn’t always mean shrinkage of the expertise that goes into making the design. Shrinking the canvas for designing could sometimes require more expertise and control of proportion and finishing. A well-executed micro-design depends on details such as: Fine motifs that remain recognisable even at a smaller scale Precise placement of diamonds or gemstones Balanced proportions between the design and the stones Clean finishing that keeps delicate pieces refined rather than crowded A tiny floral pattern, geometric form or symbolic motif can therefore carry considerable craftsmanship. But when the detail is carefully designed, what happens when the jewellery becomes part of everyday style rather than being saved for a special occasion? How Lightweight Jewellery Fits Into Everyday Style That is when light jewellery starts transforming its function. A light necklace could go along with your office wear during the morning and with your dinner dress during the night. A thin ring could be worn on a separate finger by itself or with other rings. This versatility opens up simple ways to personalise a look: Layer fine necklaces at different lengths Stack slim rings for a more expressive combination Pair delicate earrings with minimal other jewellery Mix texture or metal to make contrasts Keep only one piece that holds significance for daily wear Because the style of jewellery is not dictated by the jewellery but can be left to the decision of the person wearing it, lightweight jewellery is of far greater value. When Jewellery Becomes Personal Every small piece of jewelry has its own history. This insignificant little necklace may tell you your whole life story, which will be somehow linked to some particular event or person in your life. That tiny ring, that you wear at all times, could be your house. It is one of those things which make the combination of micro-jewelry and luxury fit so well. That brings another quality into focus: comfort. Because what is the point of owning a beautiful piece if it rarely leaves the jewellery box? Comfort as Part of Modern Luxury Lightweight jewellery can make fine jewellery easier to live with. Smaller earrings can feel more comfortable over long hours, while lighter necklaces, bracelets and rings can be worn repeatedly without feeling cumbersome. For modern consumers, this practicality can be part of the luxury itself: Easy to wear for extended periods Simple to combine with everyday outfits Suitable for layering and repeat styling Less restrictive for regular use The result is a different relationship with jewellery. Instead of being something worn only when the occasion calls for it, it can become part of the wearer's everyday identity. What This Means for the Future of Jewellery This may be the key to understanding why the small designs and lightweight jewellery are not just a temporary trend. And that is because it marks a growing demand for luxurious items which are stylish in their design, elaborate in their making, comfortable and flexible and important without being heavy. The jewellery may be lighter. The design may be smaller. But the thought behind it can be remarkably detailed. And perhaps that answers the question we started with. When luxury becomes smaller, it does not necessarily become less significant. Sometimes, it simply gives us a reason to look closer.

Coloured Gemstones and Diamonds: Choosing the Right Stone for Your Jewellery
Why does one gemstone make you stop and look, while another simply looks beautiful? Sometimes, it is the colour. Sometimes, it is the way light moves across the stone. And sometimes, it is something harder to define: how naturally the gemstone seems to belong to the jewellery. At Jos Alukkas, where diamonds and fine jewellery come together across a diverse range of designs, choosing the right stone is about understanding these subtle differences as much as admiring their beauty. From the brilliance of diamonds to the distinctive character of coloured gemstones, the right choice begins when you look beyond the sparkle and discover what makes a stone truly suited to the jewellery you have in mind.  Begin With the Feeling You Want Indeed, there could be a change in the nature of the piece of jewellery depending on the type of stones used - diamonds or coloured stones. In cases where diamonds are incorporated, they bring elegance to the piece of jewellery whereas in cases where coloured stones like sapphires, rubies and emeralds are used, they bring about colour elements and special effects. Consider the impression that you wish to convey through this piece. Is it going to be something subtle and functional or do you want the stone to make an immediate impression on everybody? It could be enough to limit your options, but it is not the end of the process since the stone needs to have its own purpose as well. Consider How Often It Will Be Worn The type of jewellery that is chosen to be worn for occasions like engagement rings or daily wearing will be subjected to different circumstances from those worn only occasionally like a pendant or earrings. According to the Mohs Scale of mineral hardness, the diamond appears at number 10 while ruby and sapphire appear at 9.This shows that all of them are durable enough for wearing. However, proper care should be taken when wearing emeralds. So, the gemstone that looks perfect in the display case may not always be the most practical choice for your lifestyle. That makes the next question worth considering: what should you actually look for in the stone itself? Look Closely at Colour and Quality Coloured gemstones usually depend on colour for their distinctive properties. Hue refers to the actual color, while the tone refers to the lightness or darkness of the color. The level of saturation refers to the intensity of the color. Diamonds are evaluated based on different criteria. In particular, the 4Cs (cut, colour, clarity and carat) give an insight into diamond’s quality. Carat relates to weight, not necessarily to its size. On the other hand, cut is a very important factor which affects how well a diamond reflects light. Yet even a high-quality gemstone can look very different depending on what happens next. The cut and setting can completely change its presence. Let the Setting Complete the Picture A harmony exists between the two. The correct amount of diamonds in a simple solitaire ring will produce wonderful fire, while the colored stone requires a suitable setting that gives it adequate space to sparkle. The choice of metal can influence the overall appearance too. White gold or platinum can create a crisp, contemporary look, while yellow and rose gold can add warmth to both diamonds and coloured stones. Halo settings can increase the sense of brilliance, whereas bezel or three-stone designs can create a more distinctive silhouette. This is also where combining gemstones becomes an interesting possibility. Why Choose Between Them? Diamonds do not have to compete with colored gemstones for space as the two can co-exist very well. This is illustrated by the use of diamonds to surround a sapphire since there will definitely be compatibility between the two gemstones in terms of color and brilliance. This approach gives jewellery another layer of character without moving too far from the timeless appeal of diamonds. Find the Stone That Feels Like Yours No absolute answer can be given concerning whether diamonds or gemstones would be a better option. This would depend on many factors including one’s preference, use of the jewelry, how often they will wear it, and the amount of care they are willing to put into it. Diamonds might be just the perfect jewellery for individuals who appreciate classic brilliance and versatility. Coloured gems would be perfect if colour and personality are what really matter. And for those who simply cannot make up their mind, mixing both might prove to be a great idea. As after all, the right gemstone might not always be the brightest one seen under the light in a jewellery store. It might be the one that remains right no matter how the lighting changes, no matter what occasion it becomes part of – years down the road.

How to Buy Jewellery Online Safely
Online jewellery shopping offers the excitement of discovering a beautiful piece from the comfort of home. But when the product cannot be held, examined or tried on, confidence becomes just as important as the design itself. Knowing what to check can make every online jewellery purchase safer, smarter and more reassuring. A beautiful piece of jewellery can catch your attention in seconds. You may be casually browsing online when a particular necklace, ring or bracelet suddenly makes you stop and look twice. At Jos Alukkas, online jewellery shopping brings that experience closer, making it easier to explore designs and find something that feels just right. However, one thing remains, which may break the enthusiasm right away – Is it possible to trust your purchase? Different from the situation when one buys jewellery at a store, in the first case, the buyer will not have the opportunity to hold or touch the product, examine its quality and try them on. Nonetheless, it should not be considered as a danger while buying jewellery online. It all depends on one’s knowledge about it. Some simple checks will help to make your online jewellery buying process much safer and more confident. Start With the Jeweller Before you fall in love with a design, take a moment to look at who is selling it. Select a jeweller who has been in business for a long time and has relevant information about the company available to customers. Customer reviews may provide further insights into how a jeweller does business and delivers. A website that looks professional alone will not be sufficient. The jeweller must be open to all information related to its products and service policies. After ensuring the credibility of the seller, one may proceed to the selection of jewellery. Look Beyond the Photograph A photograph can show you how beautiful a piece looks, but it cannot tell you everything you need to know. Read through the product description very well to note down the material used, purity of the metal, weight, dimensions and any other information concerning the stones that will be on the piece. In the case of gold jewellery, find out if it is 18K or 22K. For diamond jewellery, find information related to the diamond. And if any doubt arises, get in touch with the jeweller before purchasing the piece. Check Hallmarking and Certification When buying precious jewellery, authenticity matters. Make sure to have an appropriate hallmark or certification based on the type of jewellery that you will be buying. This may give you some insight into the important characteristics of the metal or gemstones. This becomes even more necessary when you are investing quite heavily into a particular piece of jewellery. Don’t Let the Price Decide Alone  An attractive price can make you want to complete a purchase immediately. But before you do, look a little closer. Understand what the final price includes. Depending on the piece, it may cover the metal value, making charges, gemstones, taxes and other applicable costs. If a price seems unusually low, ask why. It is possible to analyze the same items by other well-known jewellers, thus, getting an idea if the price is adequate. In case you get what you paid for, you feel satisfied; otherwise, there will always be some doubts. Read the Policies Before Buying Once you have found a design you love, it is easy to overlook the terms and conditions. Do not skip them. Always read about the return, exchange and refund policies prior to purchasing. In addition, read about delivery times, and know what will happen if the jewellery arrives damaged or if it is different from what was purchased. All of these things can be overlooked if nothing goes wrong, but they can make all the difference if anything does. Make Your Payment Securely Finally, make the payments using the jeweller’s official website or any secure gateway for payments. Do not use unknown links, and never provide your financial details using unknown methods. Once your order has been placed, store your confirmation and purchase details until you receive the jewellery. The Safest Purchase Is an Informed One There is no need to compromise between convenience and reliability when buying jewellery online. With a reliable jeweller, knowledge of the specifications of the product, knowledge of hallmarking and certifications, comparison of prices and safe payment, one can purchase jewellery online. At Jos Alukkas, the online jewellery purchase becomes easy as it becomes convenient to explore different designs and make a selection that suits your needs. This is because when purchasing jewellery, which is an investment, it is equally important to know what you are buying. After all, discovering the perfect piece should be exciting. And when it arrives at your doorstep, that excitement should come with the confidence that you made the right choice.
