What sets genuine gold apart from plating or fake gold? International standards normally consider anything less than 10 karats of gold or 41.7% gold to be fake. A few quick tests that employ materials you likely already have, including water, vinegar, and magnets, can be performed at home to determine the purity of your gold or jewelry. You won’t need to be a professional jeweler to follow the methods we’ll lead you through to test your gold, and you’ll be able to determine whether or not it is genuine without delay. in this video, I am going to be showing you How to Tell if Gold Is Real now let’s begin.
#1. | Once the gold has been submerged in a jug of water, you should test to see if it sinks by adding a few drops of vinegar to the surface.
It is necessary to choose a container that can accommodate both the water and the gold that you wish to analyze. Given that the temperature of the water is not crucial, lukewarm water can be used. Real gold falls to the jug’s bottom without a trace due to its density. Gold impersonations are lighter and float.
- Although real gold doesn’t rust or tarnish when it gets wet, if you see a stain, it’s probably plated gold if you see one.
- Your gold or jewelry item should be placed on a level surface. After using an eyedropper to apply some vinegar, allow for around 15 minutes to pass. Real gold will not change color, unlike fake gold.
- In a glass jar, you can also soak the gold in vinegar for 15 minutes. There is a slight increase in danger associated with this process because vinegar has the ability to damage semi-precious stones on gold jewelry.
#2. | Identify any areas where the gold has faded that have obvious discolorations.
Plating on gold frequently rubs off over time since gold is a very soft metal. Coins and jewelry edges are the ideal areas to look for hidden items. All throughout the day, these patches frequently rub against your skin and clothes. You can tell whether something is plated and not genuine gold if you can see another metal underneath the gold.
- A silver hue, for instance, could be a sign of titanium or silver. Copper or brass could be indicated by a red colour.
#3. | Keep track of any skin stains that may have appeared after wearing or handling the gold.
If you notice any black or green markings, they are caused by other metals because pure gold does not react with your skin’s sweat or oil. Copper leaves green marks, but silver leaves black. You may have less pure gold than you think if you have a lot of these marks on your skin.
- Do not forget that the majority of gold objects are alloys of gold and other metals. These stains can be left behind even by items of jewelry that are 14K, or 58.3% gold. Verify the authenticity of your gold with additional tests as well.
#4. | To test whether the gold adheres to a magnet, hold it up.
For this test, you’ll need a powerful magnet that can draw even metal alloys. See how the gold responds when the magnet is moved over it. Avoid falling for anything that sticks since gold is not magnetic. If the magnet attracts the gold, it is either phony or impure.
- Perhaps ordinary household magnets are insufficiently powerful. A strong neodymium magnet can be purchased at a home improvement store for improved precision.
- Because counterfeit gold can be created using non-magnetic metals like stainless steel, the magnet test is not infallible. Moreover, magnetic metals like iron are used to create some genuine gold products.
#5. | On unglazed porcelain, look for any gold streaks that may have remained.
Make sure you’re using a ceramic object that isn’t coated in glaze, even though this could affect the results of the test. Drag your thing across the plate as you observe some pieces of gold falling off. If there is a black stripe on your gold, it is likely false. Real gold is typically indicated by a gold streak.
- Try purchasing a ceramic tile or plate that isn’t glazed online or at your local home improvement store.
- Although the gold is somewhat scratched during this test, there is usually little damage that is obvious. Compared to tests that use acid or scratching, it is far safer.
- Applying cosmetic foundation to your skin first, then dragging the gold across it once it has dried, is another method of doing this. A green or black streak is frequently left in foundation after fake gold reacts with it.
#6. | Check the gold for a designation with a formal number.
Knowing how much gold is in an item can be determined by looking at the hallmark. In jewelry clasps or ring bands, the hallmark is frequently visible. Coins and bullion frequently make it obvious on the surface. Depending on the grading method in use, the stamp is either a number between 1 and 999 or a range between 0K and 24K.
- The hallmark is there, as well as a magnifying glass. It may be difficult to distinguish by eye, especially on small gold objects like rings.
- With antique jewelry pieces, there might not be any noticeable hallmarks. The hallmark may fade over time, as it does in some cases where the jewelry was never marked. The practice of hallmarking spread throughout some regions around the 1950s, although it wasn’t legalized throughout India until the year 2000.
#7. | Determine how much gold is in your item by using the number marking.
Most coins and pieces of jewelry include additional metals in addition to pure gold. This is indicated by the trademark using two separate scales. The numbers are on a scale that ranges from 1 to 999 in Europe, with 999 denoting pure gold. A scale from 0 to 24K, with 24K denoting pure gold, is used in the US.
- More easily readable than the carat rating system is the number rating system. Having a rating of 375, for instance, indicates that your item has 37.5% gold.
- Depending on the nation you are in, different numbers represent gold. A 9K bracelet contains 37.5% gold, however in the U.S., anything 9K and beneath is not regarded as gold.
- Do not rely only on the hallmark unless you are confident you are holding gold. Fake items may contain markings that make them appear genuine.
#8. | Trying to find a letter indicating that the gold isn’t pure?
Common letters that you might see include GP, GF, and GEP. The term “plating,” denoted by these letters, denotes the application of a thin layer of gold over a different metal, such as copper or silver, by a skilled craftsperson. That is not real gold, despite the fact that your item contains a small bit of it.
- For gold plating, filling, and electroplating, respectively, the abbreviations GP, GF, and GEP are used.
- The marks may be slightly different depending on where the gold is from. A small triangle symbol, for example, on gold from India indicates the rating system’s controlling organization. A letter code, such as K, and a numerical rating are then provided for the jeweler.
#9. | Get a scale and weigh your gold piece.
Put the gold on your kitchen scale if you have one that works well. If not, appraisers and jewelers will frequently do it at no charge to you. See which jewelry or appraisal shops offer this service by giving them a call and asking around. As opposed to ounces, make sure to get the weight in grams.
- To utilize in a later computation, you need the weight in grams. A precise answer cannot be obtained if the weight is given in ounces.
#10. | The graduated cylinder should be filled halfway with water before adding more.
A big enough cylinder should be able to contain the gold. It must be marked with measurements in cubic centimeters (cc) or milliliters (mL) (cc). If you don’t have a typical graduated cylinder, you can substitute a kitchen measuring cup.
- Use vials with numerous millimeter markings on the side for a more accurate measurement during the test.
- The amount of water you use doesn’t really important as long as you leave plenty of room for the gold. If you fill the vial completely with gold before dumping it in the container, water will run out.
#11. | By reading it, you may determine the cylinder’s starting water level.
After closely checking the marks on the cylinder, take note of the water level. As it is essential to the test, you should keep a record of this measurement. Placing the vial on a level, flat surface will ensure the best possible reading.
- No matter whether your container is labeled in milliliters or cubic centimeters, it doesn’t matter. They both measure the same thing, therefore you can use either one in the test.
#12. | Record the new water level after dropping the gold into the vial and, to calculate the water level difference, subtract the measurements.
Avoid spilling any water by carefully lowering the gold into the cylinder. To avoid splashing or drenching your fingers, release it just above the water. Get the second measurement by reading the markings one more.
- A piece of paper should be used to record the second measurement. The second measurement, not the first, should be noted.
- Subtract the smaller of the two measurements—the initial measurement—from the larger value to determine how much water the gold displaced. Depending on the measurement listed on the vial, this gives you a result in milliliters or cubic centimeters.
- For instance, if the water volume increased from 17 mL (0.57 fl oz) to 18 mL (0.61 fl oz), there is a 1 mL (0.034 fl oz) difference.
#13. | Subtract the weight of the gold from the variation in water levels.
The density of the gold is calculated by dividing its mass by its volume. Analyze the results in relation to the standard density of gold, which is 19.3 g/mL, after the density has been computed. If your number is wildly off, you most likely have a fake. Have in mind, nevertheless, that some of the metal alloys used to produce imitation gold may have densities similar to that of real gold.
- Consider a piece of gold that moves 2 mL (0.068 fl oz) of water while weighing 38 g (1.3 oz), as an example. Gold has a density that is quite similar to 38 divided by 2, or 19 g/mL.
- The standard density varies a little depending on what kind of gold you have. It is approximately 12.9–13.6 g/mL for 14k yellow gold. It’s roughly 14 g/mL for 14K white gold.
- An 18K yellow gold piece typically weighs between 15.2 and 15.9 g/mL. Density ranges from 14.7 to 16.9 g/mL for an 18K white gold item.
- About 17.7 to 17.8 g/mL is the density of any 22K chunk of gold.
#14. | Buying a gold-testing kit will provide you access to the acid needed for the test.
Several bottles of nitric acid are included in testing kits for the purpose of analyzing distinct types of gold. Also, while being examined with a flat rock called a touchstone, the gold on your thing may be scraped off. You might also see needles carrying samples of white and yellow gold for comparison with your item.
- Test kit components are available online. Ask around at jewelry stores in your area. Because of its accuracy, jewelers favor this test.
#15. | To make a little scuff on the gold, use a sharp instrument.
Slightly nick the jewelry in a hidden spot, like inside a ring or under a clasp. Use a sharp item, such as a jewelry engraver, to the gold and penetrate it next. Get to the base by scratching away at the gold. A metal—gold or another—can be seen behind the top layer if the layer is removed.
- To pass nitric acid testing, your gold piece must be scratched. If the gold is sentimentally significant to you or you plan to preserve it, avoid doing the test yourself. Take it instead to a trusted jeweler.
#16. | Nitric acid should be added to the scrape.
To prevent any problems with the hazardous acid, put on latex gloves and work in a room with good ventilation. When you’re ready, look for the acid bottle with the 18K gold label. A drop of the acid should be applied directly to the scratch you made after setting the gold in a stainless steel container. You should then watch for the scratch to become green. If it turns green, you’ll instantly recognize that the gold is phony.
- Your object might be gold plated or made of a low purity alloy of metals since regular gold does not react with the acid.
- Sterling silver with a gold plating usually produces a milk-colored response. If the acid becomes gold, the brass has been gold-plated.
#17. | Use a touchstone to evaluate the gold’s purity by scratching it.
Rub it along the touchstone to produce a streak of gold flakes if you believe you may be in possession of real gold. To various areas of the streak, drop 12K, 14K, 18K, and 22K nitric acid. Return in between 20 and 40 seconds. The karat rating of your item can be determined by locating the area where acid does not dissolve the gold.
- The strength of the acids all rises, making the 22K acid stronger than the 12K acid. If the 14K acid does not dissolve the gold but the 18K acid does, then your item is most likely between 14K and 18K.
