How To Tell The Difference Between Purple Fluorite And Amethyst?

Since these stones are both similar in their color and partially by their appearance, it can be hard to distinguish between them, that is why we are using this section to give you some advice to tell them apart.


Perhaps the easiest way to tell purple fluorite and amethyst apart is to test their hardness. This will be you testing how high the resistance of a crystal is, with one of the most common methods being scratching the object with something you already know the hardness of.

It will leave a mark if it is harder, but if it is not harder than it will not leave a mark. For example a knife blade tends to be less than 7 on the MOHs scale, but more than 5, so a knife would be able to scratch purple fluorite but not amethyst.

Of course you will want to be careful when going this test, and try to control your scratch as much as possible so you do not damage the stone too much. 


If you have a raw piece of amethyst, then it should not be too hard to try and tell whether it is amethyst or purple fluorite by looking at the shape of the crystal.

For example, purple fluorite tends to form a cubic shape with its crystals, and it also has a vitreous luster, whereas an amethyst will have conchoidal fracture faces, as well as hexagonal points similar to a clear quartz.

You could also try putting your raw crystal (see also ‘7 Beautiful Raw Crystals‘) in front of a light source, it should be quite easy to look through your purple fluorite when you are doing this, however an amethyst is a lot harder to see through being more opaque.

If your crystal has been polished, a piece of purple fluorite will sometimes have bands of other colors like white, pink, or occasionally green, whereas a sphere of amethyst will usually just be purple, however they occasionally have white bands.


Both purple fluorite and amethyst are incredibly beautiful and useful crystals which you should definitely consider adding onto your collection, and even though it might be hard to tell them apart at time, they do both look slightly different and have different uses and healing properties.

As you can tell from this amethyst is one of the most popular minerals, whereas purple fluorite is a bit more obscure. However, they can both complement each other in use and appearance, so if you are struggling to choose between the pair, they can work very well together. 

If you are struggling to tell them apart, the knife hardness test is the best method to use, but make sure you are being safe with this!
