This mark will also help you to identify the manufacturer of that piece of gold and its content. Hallmarks are different and vary from county to country. If it is absent then gold might not be pure. Because real gold always carries a hallmark.

As we mentioned above, different countries have different hallmarks,  gold manufactured in America will show the letter “ K” that represents Karat. 24k means 100% pure gold. Moreover, it will change according to the purity of gold

European gold will represent it with a decimal number like “.999” or ”.583”. (.999) will represent 100% pure gold while. (.583) means gold has some other mixtures.

However, It is not necessary that you will find hallmarks on every piece of jewelry because some antique gold jewelry and some countries before the year 2001 have no concept of it. It happens most of the time that the hallmark is very small so, you must have a magnifying glass with you to check it.

Vinegar is the most common and popular kitchen item and is probably found easily in everyone’s kitchen. If not then you can buy it from the market.

If it is fake, then it will float above the bottom of your bowl. However, it is not guaranteed that gold is real or fake. It may happen sometimes that some sort of material is mixed with gold and increases its density automatically.

Moreover, gold will also not rust, so if you notice any kind of rust on your gold piece after some time of performing this test, you will know its purity. As we mentioned above if you want to know if your gold is pure or fake, you must pass multiple tests.

To perform this test you have to take some safety measures as nitric acid is harmful. So you must use butyl gloves as they are made up of synthetic rubber and will keep you safe from the hazardous reaction of nitric acid. Moreover, the room must be well ventilated and wear black glasses.

Now take a clear, plain, and smooth black stone. Rub your gold piece on it with a very gentle effort until it leaves a visible mark on the stone. Then drop some nitric acid on that area.

Remember that, during interaction with flame and heat gold starts to melt and get brighter and brighter. It’s the primary quality of pure gold.

Size and Weight Test

For this test, you must have a pure gold piece that you have tested before. Now if you are going to buy a new one then compare its weight with the old one. If it is the same then no problem you can buy it without any hesitation. 

Another thing is that you must compare its weight with its size. As we told you before that gold is denser in weight, so if you feel any difference in its weight as compared to size, then it may not be pure. It must justify its weight according to its size.
