8 Proven Ways to Identify Real Amethyst

Amethyst is a beautiful and popular gemstone that can be found in jewelry, home decor, and even in spiritual practices. However, with its popularity comes the risk of counterfeit or fake amethysts being sold as genuine ones. If you’re wondering whether or not your amethyst is real, there are several ways to tell.

The Color of Amethyst

One of the easiest ways to determine if your amethyst is real is by looking at its color. Real amethysts will have a rich, deep purple color that ranges from light lavender to intense violet. The color should be consistent throughout the entire gemstone. If the color is too light or too dark, or if it has uneven patches of color, then it may not be a genuine amethyst.

Hardness Test

Another way to test if your amethyst is real is by doing a hardness test. Amethysts are relatively hard gemstones with a hardness rating of 7 on the Mohs scale. This means that they should be able to scratch glass without being scratched themselves. Take a piece of glass and try to scratch it with your amethyst. If your amethyst leaves a scratch on the glass, then it’s likely that it’s a genuine one. However, if the amethyst gets scratched itself, then it may not be real.


Real amethysts are transparent, meaning that you should be able to see through them clearly. If your amethyst is cloudy or has visible inclusions, then it may not be a genuine one. However, some natural amethysts do have inclusions, so this isn’t always a definitive test.

Heat Test

One way to distinguish between a synthetic amethyst and a genuine one is by performing a heat test. Heat destroys the color of synthetic amethyst, but genuine amethysts retain their color when heated. To perform this test, heat up a small area of your amethyst using a lighter or a match. If the color fades or disappears, then it’s likely that your amethyst is synthetic.

Weight and Size

Real amethysts are typically heavy for their size because they’re denser than most other gemstones. If your amethyst feels light for its size, then it may not be genuine. Additionally, if your amethyst is larger than average, it may be more likely to be fake because large amethysts are rare and expensive.

Refractive Index

The refractive index of an amethyst is a measure of how much light bends when it passes through the gemstone. Genuine amethysts have a refractive index of 1.544-1.553, which means that they bend light at a specific angle. To test the refractive index of your amethyst, place it on a piece of white paper with printed text behind it. If the text appears doubled when viewed through the amethyst, then it’s likely that your amethyst is genuine.

UV Light Test

Some amethysts contain trace amounts of iron, which can cause them to fluoresce under UV light. This is a common characteristic of genuine amethysts, but it isn’t always definitive because some synthetic amethysts can also fluoresce. To perform this test, shine a UV light on your amethyst and observe if it emits any fluorescence.

Scratch Test

Another way to determine the authenticity of your amethyst is to do a scratch test. Real amethysts are harder than fakes, so they should be able to scratch softer materials. Use a sharp object like a knife or a needle to try to scratch the surface of your amethyst. If the surface is easily scratched, then it’s likely that the amethyst is fake.


In conclusion, there are several ways to tell if your amethyst is real, including examining its color, doing a hardness test, checking for transparency, performing a heat test, measuring its weight and size, testing the refractive index, using UV light, and doing a scratch test. While none of these tests are foolproof, by combining several of them, you can get a better idea of whether or not your amethyst is genuine. If you’re still unsure, it’s always best to consult with a professional gemologist who can give you a definitive answer.
