Amethyst vs Tanzanite: 5 differences to highlight

Color palette

When you first see Amethyst and Tanzanite side by side, at the first glance you will notice that they are both purple stones.

However, if you take a second more analytical look you are going to find out that the colors are slightly different.

Amethyst presents a true purple color that varies in intensity.

Some Amethyst stones exhibit deep purple shades and others have a transparent pastel purple hue.

On the other hand, if you compare it to the color displayed by Tanzanite, you are going to notice that its color has a blue tint mixed with purple.

So, we can clearly conclude that the color aspect is one of the most crucial points that will guide us to separate between Amethyst and Tanzanite.

Mineral composition

Another major factor that creates a sharp distinction between Amethyst and Tanzanite is the mineral composition.

These two crystals are composed of different mineral components.

Let’s talk first about Tanzanite.

Its mineralogical description implies that it is a transparent zoisite, a mineral itself belonging to the silicate family.

What naturally provides it this spectrum of colors that ranges from blue azure to purple, is the presence of traces of chromium and vanadium. These two important mineral elements give Tanzanite its distinct bluish-violet hue.

Plus, the hardness of the gem can range from 6 to 6.5 on the Mohs scale of hardness.

Amethyst vs Tanzanite

You may encounter some Tanzanite with deep blue shades with little to no violet hues, this characteristic color reflects the exposure to high temperatures.

Resulting of volcanic activity in the Kilimanjaro mountain range (in Africa), it is quite impressive to know that this mineral formed more than 585 million years ago in schists, gneisses, and amphibolites resulting from the metamorphism of calcium rocks.

On the other spectrum, Amethyst is way more different in terms of mineral composition.

Amethyst is a component of the purple quartz family and it is composed of silicon dioxide.

On the Mohs scale, its hardness is 7 and its density is around 2.6.

This quartz crystal varies between a very intense purple hue to transparent faded purple shades, which is mainly due to the iron impurities that can be found in its composition.


Rarity is one of the most essential factors that reveal the big difference between Amethyst and Tanzanite.

Tanzanite is considered one of the rarest gemstones in the world!

That is because of where it is extracted, in other words, you can find Tanzanite in one unique location.

As its name reflects, Tanzanite is only found in northern Tanzania which clearly explains its rarity, plus the circumstances of its creation are quite remarkable.

Amethyst on the other hand is quite abundant.

This crystal was located in very large quantities at the beginning of the 20th century and specifically in Brazil, so we can say that amethyst gems are considered to be very recent stones.

Amethyst crystals are abundant in quantity and also in shapes, we find them in different sizes: As well purple geodes (big and small), or even as very small gems in jewelry.

Its main deposits were initially located in Uruguay and Brazil.

From now on, this stone is also extracted and exploited in other places all over the globe, for instance, Africa, South America, Russia, and Australia.

Another interesting fact to highlight is that although the most extensive amount of amethyst gemstone comes from South American countries, the specificity that can be seen in African countries is that it is much richer in color.
