Why Checking Gold Purity at Home Is Important
Everyone knows gold is a valuable and very costly metal. Some people buy gold for jewellery, while others buy it for future investment. If you buy gold and do not check how much other metal is mixed in it, you may save it for years but later, when you sell it, you might not recover your money.
If you are buying gold, you must learn the methods of checking gold purity. This can save you from loss and fraud.
With these simple steps, and without using heavy or expensive machines, you can easily check your gold before buying. The person selling the gold will also know that you are not inexperienced. They will treat you with respect and consider you a smart, professional buyer.
Now let’s start our step-by-step guide to checking the purity of gold at home without using machines.
Best Ways to Check Gold Purity at Home Without a Machine
- Magnet Test (Quick & Simple Test)
- Water Density Test (Float or Sink Test)
- Ceramic Scratch Test (Unglazed Plate Method)
- Skin Test (Body Reaction Test)
- Vinegar Test (Safe Chemical Test)
- Hallmark Checking (Most Reliable Home Method)
- Makeup/ Foundation Test

1. Magnet Test (Quick & Simple Test)
A simple and quick test is the magnet test. Take a small magnet and bring it close to your gold bar or gold jewellery. If the gold is slightly attracted to the magnet but does not stick, it means some other metal is mixed with the gold.
If the gold sticks strongly to the magnet, then understand that it is not real gold—it is another metal with a thin gold coating.
Note: These days, some fake metals also do not stick to magnets, which is why you should never rely on just one test. Always perform two or three tests for better results
2. Water Density Test (Float or Sink Test)
For this test, take a glass of water and gently drop your gold item into it. If the gold instantly sinks to the bottom, it means the gold is likely pure. But if it sinks slowly or floats on the water, then it is not real gold, because real gold is dense and heavy. Pure gold does not float; it sinks immediately.
3. Ceramic Scratch Test (Unglazed Plate Method)
This is a simple test. Take a white ceramic plate with a rough surface and gently rub your gold item on it. Look closely at the mark it leaves. If the mark is yellow or gold in color, it means the gold is likely pure. If the mark is black or another color, it means the item is not real gold—only the outer layer is gold, and the inside is another metal.
Do not use this method on new gold jewellery, because it can leave a tiny scratch on the gold.
4. Skin Test (Body Reaction Test)
This is another simple test to identify gold purity or real gold. In this test, wear a gold ring or bangle for a few hours, then remove it and closely examine your skin. If you see green or black marks where the jewellery was, it means the gold is not pure or has low purity, as it is mixed with other metals. Real gold does not leave any marks on the skin.
5. Vinegar Test (Safe Chemical Test)
Take a bowl and put your gold jewellery or other gold items in it. Add a few drops of white vinegar. If the gold is real, there will be no reaction. If it changes color or produces bubbles, then it is fake or a low-purity gold item
6. Hallmark Checking (Most Reliable Home Method)
This is one of the most reliable and easy ways to check gold. Every genuine gold jewellery piece has a stamp called a hallmark. It usually looks like 900, 916, 999, or 22k, 21k, 24k, or 18k.
To see this stamp, use a magnifying glass and look closely at the jewellery.
- If your gold is 24k, the mark is 999.
- If it is 22k, the mark is 916.
- If it is 18k, the mark is 750.
If you do not see this stamp, it could mean the item is handmade, antique, or fake gold.
7. Makeup/ Foundation Test
This is a surprisingly accurate test. Take liquid makeup foundation and apply it on the back of your hand, then let it dry. Once dry, gently rub your gold item on that spot. If the gold leaves a black line or mark, it means the gold is real. If no mark appears, the gold is fake.
