The Smell Test: Ideal For Small Gold Pieces

How to Tell Real Gold from Fake

While this test is far from being the most reliable way to tell real gold from fake gold, it’s one of the easiest and quickest to do, and will not damage your jewelry.

You know that awful smell your hands get after you hold some coins in it for some time? We’re looking for that smell in this test.

This test can be done in three easy steps:

  • Make sure your hands are sweaty , then place your gold jewelry of choice in the palm of your hand
  • Place your other hand over it, and vigorously rub your hands together with your jewelry between them
  • Finally, place your nose close to your palms and smell them. If it does not smell like anything in particular, then your jewelry has passed the test. But if your hands smell like coins, then it’s quite likely you’re dealing with fake gold.
  • You see, one cheap metal used in the making of coinage is brass, a mixture of copper and zinc along with other materials. Brass can look like gold, especially if made into an alloy with other metal, to try to approximate gold’s weight and color. However, brass is much more reactive than gold when in contact with salty water and air, it produces the characteristic acidic smell most coins have due to an electrolytic reaction.

    As such, if your “gold” jewelry exhibits the same smell, it very likely is not real gold, or at least not pure gold. But even if your gold jewelry passes this test, it can still be fake gold.

    How To Tell If Gold Is Real With A Makeup Test

    If you’d like to take the skin test one step further, you can also learn how to test gold at home with makeup. Let’s explore how to tell if gold is real with makeup. You’ll need liquid foundation makeup and powder.

    First, coat the back of your hand, or your forehead, with a thin layer of foundation and then your powder. Wait until the foundation thoroughly dries. Once the foundation dries, press the gold into your skin. Then, lightly rub the gold against the foundation. If your gold leaves a line or black streak, it is very likely to be authentic gold. If you do not see a line or black streak, the object is likely to be another metal or gold-plated.

    Gold Testing: Ways To Know If Your Jewelry Is The Real Deal

    You cannot tell the difference between real and fake gold just by at first glance. That is why it is easy for dishonest sellers to dupe people into buying fake items. Fortunately, there are ways to know if your jewelry is the real deal or merely fools gold:

    Look for marks

    Manufacturers put stamps in the clasps of bracelets, necklaces and rings to let you know its purity. If you do not find one in your jewelry, chances are it may not be genuine. Older jewelries are the exception, however, as it was only recently that the method was applied. Suspicious marks, dents, shapes and discolorations around the edges are also some of the telltale signs of fake gold.

    Check the statistics

    People have standards on the size and weight of real gold depending on the karat. Research the standard dimensions of pure gold thoroughly. Using calipers, measure the diameter, thickness, size and weight of your jewelry. If it does not match the usual dimensions of its kind, then it is most probably gold clad or one that is mixed with other metals. Drop your jewelry in the water real gold usually sinks.

    Drop nitric acid

    Real gold does not react to nitric acid. Try the acid test if physical examination does not work. Scratch lightly on the jewelrys surface and apply a small amount of nitric acid on it using a dropper. If the surface turns green, your jewelry might be gold clad. A milky substance appears if your gold contains sterling.

    Apply cosmetics

    Use a magnet

    How To Tell If Gold Is Real: The Floating Test

    Garfield Refining

    Take a vial or jug and fill up at least half of it with water. The temperature of the water does not have any effect on this test, so you can use room temperature or lukewarm water.

    Drop your gold item gently into the water and see what it does. A genuine piece of gold is dense and heavy, so it will quickly sink to the bottom of the container. Counterfeits are likely to float or sink slowly.

    Test The Items Density

    The density of gold is approximately 19.3 grams per milliliter . The closer your gold items density is to this figure, the more real gold it contains. To find the density of your gold item, you will need a scale that measures in grams and a container with markings in milliliters that is big enough to hold the item with room to spare.

    Weigh your item and note its weight in grams. Next, place your container on a flat surface and half-fill it with water. Record how full the container is in milliliters. Carefully lower your item into the container so the water doesnt splash over the sides. Write down the new water level. Then subtract the first measurement from the second to find out how many milliliters of water your item displaced. This gives you the items volume.

    To find the density of your gold item, divide its volume by its weight. For example, if your item weighs 40 grams and has a volume of 2.2 milliliters, its density will be 40 / 2.2, which is 18.18 g/mL. Since the density of gold is 19.3 g/mL, the chances are your item is mostly real gold. Of course, other metals have a weight similar to gold, so this test is a good guide but not completely foolproof.

    How To Tell If Gold Is Real: The Secret Weapon: Acid Tests

    How to tell if gold is real? When it does not react with any acidic element. So, you can use vinegar or nitric acid to find out its authenticity.

    a) Testing with Vinegar

    Gold is almost inert, so vinegar’s acidic element cannot change its color or properties. Use white vinegar since it’s the most acidic of all types.

    Just add a couple of drops of vinegar to the jewelry piece and see if the color changes. It’s fake if it does otherwise, you have a real piece. Give it at least 15 minutes to ensure enough time for the vinegar to set in and cause a reaction.

    b) Testing Gold with Nitric Acid

    Nitric acid does not react with gold, but it can melt the common metals in fake items. Careless application may ruin the ornament.

    Use a touchstone or a jewelry engraver to create a tiny but slightly deep scratch in a part that is not easily visible. Pour a few drops of acid on the scratch mark and if it turns green or milk-white, the piece is not real.

    You can do the same test with aqua regia too, which can melt gold. Pour a drop on the scratch mark to see if it disappears. If it does, your jewelry piece is genuine.

    Nitric Acid Gold Test

    This method is only recommended for scrap jewelry, not gold jewelry you intend on wearing. Essentially, you make a tiny indent or scratch with a nail file. Then youll drop nitric acid into the scratch. If theres a visible reaction, the gold is fake. If nothing happens, the gold is most likely real. Take care when working with acid as this method is best left to a trained professional in a safe environment.

    Kinds Of Gold Materials

    In identifying fake gold, an important starting point is to gain knowledge about the different types of gold jewelries. To the untrained eye, all gold products are the same and differ only in the color due to finishing applied. There are however more subtle differences in various gold products which we shall discuss shortly.

    The first classification is based on time in which we can divide gold into new, old and fake gold.

  • New Gold: This can be compared to freshly baked bread just brought out of the oven. New gold refers to gold products that are produced or manufactured immediately after refining and purifying the raw gold. New gold is what youre likely to find on display in the show glasses of the worlds top exquisite jewelry stores.
  • Old Gold: Products made from old gold are sort of like a refined version. Old gold products are made either exclusively from recycling old jewelry or combining the recycled old jewelry with freshly melted raw gold. Old gold is often slightly cheaper than new gold in the sense that less raw gold is required in producing it.The old materials can actually be recycled to standard plate-like ingots material. The raw molten gold is then used in the gold jewelry vacuum casting machine for the finishing of jewelry products. A few unscrupulous dealers make a slightly higher profit by selling jewelry made from old gold at the price of new gold. This is because the difference is not easy to spot.

    Test : The Magnet Test

    This is another relatively easy test to carry out. However, it will be more difficult to do say at a jewelry shop or place where you are considering buying a new piece of jewelry. Gold is not magnetic!

    True solid, 24k gold will not be attracted to a magnet at all. If you hold a magnet up to a piece of gold and it is strongly attracted to it, more than likely the gold is fake.

    However, keep in mind that nearly all jewelry will not be solid 24k gold. Because it is alloyed with other metals, you need to be careful with this test.

    We recommend getting a very strong magnet to use for your test. Also, keep in mind when dealing with necklaces or bracelets that the clasp on the gold may not be real gold, and that is okay. If that is the only part attracted to the magnet, you know that the rest of the gold is real.

    If the jewelry you test is attracted to the magnet, there are clearly other metals present. In these cases, there is probably a small amount of real gold and more of other metals.

    If the gold is supposed to be a higher karat solid gold, you are probably dealing with a fake.

    How to Test for Fake Gold and Silver

    Have we inspired you to go shopping? Great! Here are some awesome gold jewelry finds that we are absolutely loving right now. Happy shopping!

    Rest assured, the jewelry here is definitely real gold, not fake. However, now that you know the differences between solid gold, gold-filled, and gold plated, be sure to pay attention so that you can make the right decision based on what you are looking for!

    Are you unsure of how to decide? Ask yourself this set of questions to make the right decision:

    What is your budget?

    If you have a very limited budget and want jewelry that you can wear once or twice, go with gold plated. If you want something that is durable, but that wont break the bank, go with gold filled. Looking for a true investment piece? Go for solid gold.

    Do you have sensitive skin?

    If the answer is yes, gold plated jewelry should pretty much be out right away unless you know you will only wear the jewelry for one occasion.

    Are you okay with maintenance?

    If you know you dont typically clean your jewelry, we recommend investing in either solid gold or gold filled jewelry that has 14k gold or higher.

    The lower karat you go, the higher the likelihood you will have to clean your gold as it may tarnish. If you are fine with always replacing your jewelry instead of maintaining it, you could go with gold plated.

    The Bullion Dna Reader For Maple Leaf Coins

    Only gold dealers who take part in the Royal Canadian Mints Bullion DNA programme for the identification of Canadian-made gold, silver, platinum, and palladium coins receive a special reader linked to a database. Using a technology similar to an iris scan, it scans the surface of a Maple Leaf coin and compares it in real time with a surface print from a database in Canada. The database contains the scans of every coin produced since the introduction of the reader. According to the manufacturer, this process is one hundred percent safe, and other coin suppliers might well follow this example.

    Use Makeup To Test Gold At Home

    Another way to test your gold at home is to use a liquid foundation. It may not be as reliable as other sources when it comes to testing your gold but it is good enough to know if the gold is real or fake. Pour some of the liquid foundations on your hand, blend it in your skin and let it dry. Take your gold and rub it on the area where you have applied the foundation. If that area turns black or rubbing the gold leaves a black mark behind then it is evident that the gold is pure. But if rubbing the gold does not affect the foundation applied area, we are sorry to tell you that the gold is not real.

    Advanced Fake Gold Detection Techniques

  • Melting and Sampling spectrum detection: This is a more vigorous test, but is worth the effort and slight cost. Melting and sampling spectrum detection takes advantage of a thermo-analytical technique known as Differential Scanning Calorimetry. A sample of the gold to be analyzed is placed in a Differential Scanning Calorimeter alongside a reference gold sample. The same temperature intensity is applied both to the sample and the reference gold material. The difference in the amount of heat needed to increase the temperature of the sample as compared to the reference is recorded. It is this heat difference that helps to analyze how different or similar a piece of gold is from the original. Fake gold is easily detected with this technique as it will have widely varying heat properties from real gold.
  • Metallographic Analysis: This technique has wide usage and can be found in literature where it has been used for detection of fake gold and silver coins. The results can similarly be applied for the detection of fake gold in jewelry production. Metallographic analysis applies the principles of metallography in the identification of fake gold. This often involves microscopy. Optical microscopy or scanning electron microscopy with energy-dispersive x-ray analysis are two types of microscopy often employed. Since the properties of real gold are already known to experts. A comparison of the sample properties with the expected ones will reveal the originality or otherwise.

    A Final Word Of Caution

    This article only lists five of the easiest methods to test your gold. As said before, a skilled craftsman may be able to replicate most qualities of real gold using other elements, so even if your piece passes a few of these tests, it’s always good to conduct others, just to make sure. The more tests it passes, the more likely it is to be genuine gold.

    There are other ways to test your gold, but these usually require special materials or special tools.

    And finally, remember, however, that it is always better to have a professional test your gold piece.

    Good luck!
