How to test if a crystal is real or fake?

You will find the market flooded with fake crystals. The fake ones look as good as the genuine ones and that’s why it makes it so difficult to spot the real crystal. Here are some of the ways you can test whether a crystal is real or fake.

Understand the various kinds of crystals

Natural crystals are those that are found in nature. They form over a long time and are found deep in the earth. These crystals take a long time to form and they are not intervened by anything. Synthetic crystals are those that are made in labs. They have the same physical and chemical properties like the natural crystals. They even look same, except that they are made within a very short time. The synthetic crystals cost a lot less than the natural crystals.

Fake crystals have a different chemical composition than a natural crystal. They can be ceramic, plastic or even glass. They are often painted.

Look at their appearance

One way to differentiate between a natural crystal and a synthetic crystal is that you will find flaws in the natural crystal. They won’t have pure color all the way. If you see that the color is unnatural then there is a chance that the crystal is fake. If you look at the base or tip of the crystal, you may notice some paint. That tells that the crystal is fake. If you see bubbles inside the crystal then the crystal is not real, it’s glass. If the crystal looks perfect, then it is probably fake.


It’s a test that can tell you whether the crystal is a quartz or a glass. When you place the crystal on top of books, the words will become magnified if it’s glass. If it’s real quartz, then the words will appear same.

UV light test

You can use a black light to test turquoise. If the turquoise is fake, it will fluoresce. Same is true for heat-treated sapphires and rubies. Real crystals won’t show these signs.

Crystals are very precious. Before buying these you should check whether the crystal is genuine and fake. You can use the various tests just explained in order to test the crystal.
