How to test gold at home? That big concerns are raised when it is known that the gold you have bought is not correct or that the gold is counterfeit.
People’s houses are small or big. Women have a different fascination with gold. Many people save their money in gold.
However, there are many easy ways to get rid of those big concerns at Home. There is no cost to follow these methods. No special time needs to spend.
There are two things to keep in mind when buying gold or gold jewelry.
- How pure is gold?
To check the good quality gold, you have to look at the hallmark mark in the ornament. Hallmarking is the identification that represents the purity of the metal in question.
- Whether the price at which I am buying gold is correct as a measure of its purity.
24Karat gold means pure gold, which means it contains 100% gold. But does that mean 100% pure?
We need to know jewelry never made of 24Karat Gold. A minimum of 22 Karat gold is required for Ornaments. What is the value of that 22 karat gold as of today’s gold market price? This is something you need to know before buying jewelry.
So let’s see how we can test the Gold Purity in a few domestic ways
1.Examine your own skin
If you want to check the gold purity of your new wedding Ring or finger Ring. Then wear it at the finger for a few weeks.
If it reacts to your skin, it means the skin becomes black or green, then that is fake gold. Or the unit of real gold in the metal is much less.
If the metal contains too much iron or lead the skin color will be black and if there is a brass mix then the skin color will be green. If your neck turns red with a chain or necklace, then you have to assume that the proportion of Brass in the jewelry is high.
In addition, if your jewelry is in any other design category, you can use the following methods.
2. Examine with strong Magnet
We can test gold jewelry or pure gold at home with Magnets. We need a strong magnet to perform this test. Such as a ladies Purse magnet or a magnet attached to a speaker or a magnet purchased from a hardware store.
If this magnet leads to that gold. If the magnet pulls the gold, then the gold is fake. Because real gold does not attract by magnets.
Silver on the other hand does not attract magnets. So other methods you have to follow.
3. Edges of the whole Jewelry Faded in color?
The jewelry you bought, easily understands the purity of gold through this method at home. Place the jewelry under a table lamp after a few days of use. Look carefully at the edges of the jewelry. If you have difficulty with the naked eye, check the ornament through 10x-eyeglass, which is available on the market.
The color of the edge is faded from the original gold color, you should understand jewelry is counterfeit.
You should realize that the money you paid is not right for that ornament. Possibly the gold seller sold you gold-plated jewelry.
If you are unsatisfied with this method, you can use the following method.
4. Notice if the Surface of the Gold is Smooth
This method is very simple and effective. Gold or gold jewelry does not have any stains or holes on the surface. Because the density of pure gold is much higher.
Check properly the surface of the jewelry through 10x eyeglasses, If there are any spots or holes, then it must be assumed, the jewelry is not real. it could gold-plated jewelry. Or maybe used other metal.
5.How to Test Gold at Home by Your Own Teeth
This method can be a little dangerous if you do not do it carefully. This test is suitable for testing 24karat gold. 24 Karat gold is usually soft. If you carefully do pressure on gold with your own teeth. Gold will imprint your teeth.
If do not make an imprint, never put too much pressure. It can damage your teeth. The gold is not 24 karat. Don’t have any spot or imprint with a little pressure. Gold bars usually made of 24 karat gold. In ancient times real gold detected by this simple method.
6. How to Test Gold at Home through Dropping some Vinegar on the Surface
The purity of gold can be verified using vinegar of our Kitchen. Before that, we have to see if there is any stone in that jewelry. If there is a stone, whether it is semiprecious or not. Because when Semiprecious Stone comes in contact with vinegar, the stone can be damaged.
Put the jewelry in a pot and put some vinegar in it and leave it for a while. After holding for a while, pick up the jewelry, and inspect it carefully.
If the color of the jewelry change, or becomes black. Then you have to understand that gold is not real gold. There should be no reaction to the touch of real gold with vinegar.
There are also some methods by which we can identify the real gold.
7. Test the gold with Baking Soda and Acid Kits and Black Stone
The kit used to apply this method is available in various e-commerce markets. Needs to rub your gold on the black stone which is available in this kit. If the gold jewelry is of different designs, rub it on that black stone. If you have any silver jewelry, you can rub it also.
After rubbing those metals, gold, silver-colored spots on black stone. Then one drop or two drops of the solution thrown on the color spot on Black stone. Which contains a mixture of Nitric acid and other compounds.
This method should operate very carefully. If you feel the need, you can wear gloves on both hands. Drop the solution on the stone and wait for 5 to 10 minutes. Then the acid should wash off with baking soda mixed with water.
Then you have to look at the spots on the top of the stone. You could notice the silver stain has gone. And the golden colors still visible. But the one that has become lighter in color is the 18 Karat gold with less refinement and the stain that has not changed in any way is pure 22 Karat gold.
But during this test, it must be remembered that the Jewelry should not have any stone or Pearl. This is because nitric acid or baking soda can damage any stone. So through this method, you could test gold at home. If you have doubts about the test, you can try other methods.
8. Guess the Gold Standard by Friction on the Ceramic Plate
We can check the purity of gold through a Porcelain or Ceramic plate. In this porcelain or ceramic plate, you have to grind the gold or gold jewelry you mentioned.
Then notice if there are any stains in this pot. If there is a stain, what is its color? If the color of the stain on the plate is black, then your gold or jewelry is not real. And if it shows a golden color, then you have to think that the jewelry is made of gold.
One thing I forgot to mention is that this test may cause a little stain on your gold or jewelry but it will not cause any special damage to your jewelry.
If the content of pure gold could not understand through this test. To get there, you need to follow the procedure below.
9. Check Jewelry by using Liquid Foundation Makeup
This method is not particularly reliable. However, with this method, you can find out if your gold or gold jewelry is genuine or not.
Do apply your own foundation makeup on your hands. And let that makeup stay dry. After the makeup is dry, rub your Suspicious Gold in the place of that makeup. If you see black spots in this place then your gold is not real gold.
Because real gold never creates any Black spot. The percentage of gold in this method or the percentage of Alloy may not be known. If you want to know that, you have to follow another method.
10.Verify Purity of Gold at Home through a Laboratory Bottle and Metal Density
Gold is heavier than other metals so Gold sinks in water. But If the jewelry is forged or other object filled metal, Then it will float in the water.
By the Density of gold, we can get the correct result. First of all, we need to know about the Density of pure gold.
For example, the density of 24 karate gold is 19.3 / ml, which is much higher than other metals. The more Density is there, the gold will be much purer.
To do this test you need to take a laboratory bottle. So that there is a milliliter size so that the volume of water is understood.
Fill this bottle with water and take the volume of the water. After dipping the gold in water. The height of the water changed, Take its measure.
(With the Volume of water you took earlier – now whose water Volume). Keep notes of what you get results from the process. The weight of a gram of gold that has been measured in milliliters needs to be known.
Then a formula (Density = Mass / Volume) You will get gold Density through. The closer this density is to 19.3gm / ml, the higher the purity consider of the gold.
Keep in mind that different gold densities are different. So this test should not be done if you have no idea about Gold Density. Moreover, a milliliter bottle has to be proper.
If all these objects do not have the correct information, then this test will not be able to make an accurate diagnosis.
Through all of the above methods, you can do test gold purity in the house.
Now the methods that I will say are outdoor methods.
11. Determining the Percentage of Real gold by XRF Machine
This method can never be done at home because this machine is very expensive. This machine usually uses in the manufacturing units. X-Ray Fluorescence (XRF) is an amazing method of determining the density of elements present in different metals.
Today all business is moving towards the scientific method. The XRF machine is a brief example of this. Many jewelers now use this machine to test jewelry.
To use the XRF machine, the metal mus placed under the scanning head of the machine. Prepares a statistical report of all cast metal components shortly after activating the machine. Through which we can easily find out how much real gold there is in this Gold or Gold jewelry.
In all Jewelry industries today, the purity of gold is verified through this machine.
12. Take your gold to Professional Metallurgical Engineering
If you are not satisfied with all of the above methods. And if you know any Professional person. Who is able to make an accurate analysis of gold by deep experience. You should go to Professional metallurgical engineering. But IT can be a little expensive. Before going into this method, see how valuable your jewelry is and also check that is actually good or not.

This method can be dangerous to do at home.
This test requires Nitric Acid, which is a bit difficult to buy. You can get injured by Nitric Acid.
However, if you want to, you should first wear gloves with both hands. Also, need a steel bowl. To do this test, move a little away from your home, that is, 20 to 25 meters away. This is because some gaseous fumes are produced during this test which is very harmful to health. Put gold or pieces of gold in that steel bowl.
Pour some acid into the bowl so that your jewelry is half immersed in the acid. After a while see what color smoke is created.
If the color is green, then you have to assume that your jewelry is made of any other metal instead of gold. If you see the smoke of golden color, then you should understand that your jewelry is made of Gold Plated Brass. Again, if you see the smoke of milk color, you have to understand that your jewelry is gold plated silver. If no color is seen then gold pieces or ornaments are Pure gold.
This test is dangerous, if not done with caution. So you can do other methods to test the purity of gold at home.
