Jewelers employ sophisticated machines to determine the purity of their gold, there are easy methods that you can test at home to verify if the gold you have purchased is genuine or fake.
How to Identify Gold at Home

The first and most trustworthy method is to search at an BIS Hallmark on your jewelry. In India it is called the Bureau of Indian Standards (BIS) has the authority to stamp gold. A hallmark usually comprises:
- BIS logo
- Purity in Karats (e.g. 22K or 18K) or quality (e.g. 916 in 22K)
- The center’s hallmark and signature are both stamped.
- Identification mark of the jeweler
If your ornament is missing an initial, it could not be genuine.
2. Magnet Test
Pure gold can be described as not magnetic..
- Make sure you have a strong magnet next to the object.
- If it is stuck or displays strong attraction, the object may be fake or a mixture of nickel, iron or any other metals.
- However, the weak attraction might suggest alloys, as gold jewelry typically has tiny amounts of other elements for durability.
3. Water Test
This is among the most simple home remedies:
- Make sure to fill a glass with water, then drop your gold-plated item into it.
- Real gold sinks fast because of its density.
- Gold-plated or fake items can sink or float slowly.
4. Density Check
The density of gold is approximately 19.3 grams per cubic centimeter which makes gold one of the largest metals. You can test it by doing the following:
- Check the weight of your gold piece.
- Drop it into the measuring cup containing water to measure the displacement.
- Divide the weight by the volume of displacement. If the results are near to 19 then it’s real gold.
5. Ceramic Plate Test
Use a non-glazed ceramic plate (not the shiny variety).
- Carefully scrape the gold object over it.
- Gold that is real leaves an golden streak however fake gold leaves gray or black marks.

- Place an ounce of nitric acid.
- If it disappears the mark disappears, it’s fake. If it’s not gone true gold, it’s real gold.
(Handle acid with care while wearing gloves. )

Jewelry made of fake or gold plating often fades in the color with time, particularly when it is exposed to perfumes or sweat. Be sure to check joints and edges:
- The pure gold keeps its color constant.
- Gold that has been plated could expose a different type of metal beneath.
10. Professional Confirmation
While home tests can be useful but they might not be 100 100% precise. To be sure, go to an accredited BIS-certified jeweler or test lab, where instruments such as XRF analyzers can verify that the quality is 100.
