1. Why it is important to be able to distinguish real gold from fakes
Gold has always held a special fascination for people. It is not only a symbol of wealth and status, but also a valuable metal that is used in various areas, from jewelry to electronics. For example, you can find Real gold earrings, real gold necklaces , or high quality rings made of 14k real gold
However, due to its high value, gold has also become a target for counterfeiting.
The ability to distinguish real gold from fakes is crucial for several reasons. Firstly, the value of your own piece of jewelry will decrease if you fall for a fake. Secondly, the long-term value will also decrease, as 14k real gold is durable and does not lose quality over the years - unlike a mixture with precious metals, for example.
In a world where counterfeiting is becoming increasingly sophisticated, it is more important than ever to educate yourself and acquire the knowledge necessary to confidently distinguish real gold from imitations. This not only protects the financial investment, but also the cultural and personal heritage that gold often represents.
2. Simple tests for detection
The visual test: Can you spot a gold fake?
Visual inspection is the first and often easiest step in distinguishing real gold from fakes. Although it may seem challenging at first, there are certain features and details you can look for that will help identify authenticity or at least raise suspicions about a possible fake.
Gold can have many different shades of color. Therefore, you cannot tell with the naked eye whether the gold is real or not based on the color. But many fakes or gold-plated objects will show another metal underneath when worn, or will show uneven wear that real gold does not. I.e. if you see a silver sheen under a scratch, or another color, it is probably not pure real gold, but silver and then gold-plated.
High-quality real gold jewelry is usually very well made. Irregularities, rough welds or obvious glue spots can therefore be signs of a fake.
The weight test: Does gold have a higher density than precious metals
The weight and density test is a very scientific way to check the authenticity of gold at home. You will need a special kitchen scale and a very detailed measuring cup, so it is more of a test for chemistry nerds who have the more specialized measuring equipment at home.
Gold has a very specific density that is quite different from most other metals used for counterfeiting. The density of pure gold is about 19.32 g/cm3. This home test will help you determine the density of your gold piece and compare it against that value.
What you need for the test at home:
- A precise digital kitchen scale that measures to at least two decimal places.
- A measuring cup with milliliter markings or another device to accurately measure the volume of water.
- A thread or thin string to attach the gold piece to.
- Tap water at room temperature.
Now you can go through the following three steps.
First, weigh the gold piece using a kitchen scale: Start by weighing the gold piece accurately. Write down the weight in grams. This is the weight (mass) of your gold piece.
Second: Measure the displaced water: Fill the measuring cup with water and note the initial water level. Then immerse the piece of jewelry in the water. Now note the new water level. The difference between the two water levels corresponds to the volume of the gold piece in cubic centimeters (cm³).
Third, calculate the density: To calculate the density, divide the weight (mass) of the gold piece by its volume. The formula is:
The result should be close to the density of pure gold, which is about 19.32 g/cm3. Gold alloys will have a slightly lower density due to the other metals they contain. For example, 14 karat gold has a density of about 12.9 to 14.6 g/cm3, depending on the specific alloy metals.
Was that a bit too complicated for you? Then scroll down to section 3 with the professional testing methods.
The magnet test: How attractive is your jewelry?
One of the easiest tests to check the authenticity of gold is the magnet test. However, you need a very strong magnet - a so-called "neodymium magnet". If you have one of these in your basement or workshop, this test is exactly the right one for you.
This is because gold is a non-magnetic metal, which means that if it is real gold, it should not be attracted to a magnet. However, it is important to note that this test alone does not definitively prove that an item is made of gold, as there are other non-magnetic metals as well.
What you need for the test at home:
The test is relatively simple: You hold the magnet to your piece of jewelry, for example your rings, earrings or necklaces, which you think are made of 14k real gold. If they are attracted to the magnet, it could be a fake in which real gold has been mixed with precious metals. In this case, I would go straight to the jeweler and have it double-checked by an expert.
The abrasion test: Can you rub off gold?
The abrasion test is a traditional method of checking the authenticity of gold. It relies on gold's property of being soft and malleable, which means that real gold leaves marks when rubbed.
The abrasion test can be particularly useful for gold coins or thicker gold bars, where a small abrasion is less noticeable or acceptable. Caution should be exercised with fine jewelry or gold pieces, where any damage could affect the value or aesthetics.
For the abrasion test, you need an unglazed ceramic plate, such as the one used as a base for grinding stones. Special abrasive stones for this purpose are also available commercially.
Now gently rub the gold piece on the unglazed ceramic surface. Real gold will leave a gold-colored trace on the ceramic. The color of the trace is a good indication of authenticity, as gold has a characteristic soft golden color. If the gold piece leaves a black or greenish trace, it is probably not real gold, but a gold-colored coating over another metal. Real gold traces, on the other hand, will have a distinctly golden color.
The vinegar test: Can you detect gold counterfeits with white vinegar?
The vinegar test is a simple and inexpensive method you can use at home to check the authenticity of gold. White vinegar, which you probably already have in your kitchen, can help you distinguish real gold from fakes. This test takes advantage of the chemical resistance of gold, which does not react to vinegar, unlike many other metals that can be oxidized.
Carrying out the vinegar test
- Clean the gold piece: Before performing the test, clean the gold piece thoroughly with a soft cloth to remove dirt, oils and other contaminants that could affect the reaction.
- Soak a cloth with white vinegar: Take a clean white cloth or cotton pad and soak it with white vinegar. It is important to use white vinegar because it is clear and does not contain any dyes that could distort the results.
- Test the gold piece: Gently rub the soaked cloth or cotton pad over the gold piece. Observe the metal's reaction to the vinegar.
- Assessing the reaction: Real gold should not show any visible reaction when it comes into contact with white vinegar. This means it should not change color or become oxidized. If the metal begins to discolor, oxidize, or dissolve, it is probably not real gold.
The skin test: How real gold should react when in contact with the skin
Real gold is known for its chemical resistance and its inability to react with most substances, including the natural oils and sweat that your skin secretes. This property makes gold an ideal metal for jewelry worn directly on the skin. There are some signs and reactions to look for to determine if your gold piece is real based on its interaction with your skin.
No discoloration on the skin: One of the clearest signs that you are wearing real gold is the absence of any green or black discoloration on your skin. Many metals and alloys, including those used in fake gold or gold-plated jewelry, can react with the acids in your sweat and leave a discoloration on the skin. Real gold, especially high purity gold, does not cause such discoloration.
No allergic reactions: Real gold is hypoallergenic and should not cause allergic reactions on your skin. If you notice itching, redness, or other signs of an allergic reaction after wearing a gold piece, it could be an indication that the piece is not made of pure gold or is alloyed with other metals that some people are sensitive to.
Consistency and durability: Real gold remains consistent and durable when in contact with skin under normal circumstances. It does not flake, corrode, or lose its shine or color over time. If you notice that your jewelry loses its outer layer or begins to change its appearance over time, it could be a gold coating over a less durable metal.
The stamp test: meaning of stamps on gold jewelry and indications of possible counterfeits
Stamps on gold jewelry play an important role in identifying the purity and authenticity of the metal. These stamps, often known as hallmarks, typically indicate the karat content of the gold, which expresses the percentage of pure gold in the alloy. For example, the stamp "750" stands for 18 karat gold, meaning that 75% of the material is pure gold. Here are a few things you should know about these stamps, as well as some tips on how to spot potential fakes.
Meaning of the stamps
750 (18K): Stands for 18 carat gold, with a purity of 75% pure gold.
585 (14K): Represents 14 karat gold, meaning that 58.5% of the piece is gold.
417 (10K): Indicates that the piece of jewelry contains 10 carats of gold, i.e. 41.7% pure gold.
These stamps are internationally recognized and give you quick information about the quality and value of the piece of jewelry.
How stamps can be counterfeited
But the stamps can also be fake. You should take a closer look at the following factors:
Inaccuracies and imperfections: Genuine stamps are usually very precise and clearly stamped. If the stamp looks blurry, uneven or smeared, this could be an indication of a fake.
Position and alignment: For high-quality jewelry, the stamp is placed in an inconspicuous place and is neatly aligned. Suspiciously placed or poorly aligned stamps can indicate a counterfeit.
Material examination: Sometimes the stamp itself may appear genuine, but the material does not match the purity level stated. Some counterfeiters use stamps such as "750" on gold plating or alloys with lower gold content.
3. Professional testing methods
In addition to the simple tests that you can do yourself at home, there are of course professional tests. You can find out what these are and who carries them out here.
The expert test: Can your jeweler recognize real gold?
When it comes to confirming the authenticity and quality of gold, there is hardly a more reliable method than expert testing by a professional jeweler. Jewelers and precious metal testers have the expertise, experience and specialized tools to distinguish real gold from fakes.
Jewelers are trained in precious metals and often have years of experience working with gold and other precious metals. This experience allows them to identify many fakes through visual inspection or simple tests that go beyond what laypeople can typically perform at home.
Overview of professional testing methods
Jewelers use a series of tests to determine the authenticity and purity of gold:
Acid test
In this test, the jeweler applies a small amount of acid to an inconspicuous area of the gold piece. Depending on the reaction of the acid, they can determine the karat content of the gold. Real gold is not damaged by these acids, while inferior metals and alloys are dissolved or discolored.
Electronic gold testers
Modern jewelers often have electronic testing devices that can determine whether a piece of gold is real by measuring its electrical conductivity and can often also determine the exact carat content.
X-ray fluorescence spectroscopy
Some jewelry stores use state-of-the-art X-ray fluorescence equipment to analyze the exact composition of the metal without causing any damage to the piece. This is one of the most accurate methods to confirm the authenticity of gold.
