Amethyst and its different associations

There are different types of amethyst. The rarest and therefore the most expensive are the most transparent. By letting more light through, the clearest amethysts offer exceptional reflections, oscillating between pink, blue and red. Natural amethysts are rocks of magmatic origin.

The different types of amethyst

Different extraction locations

Amethysts from Uruguay are considered the most beautiful. They are the darkest with small deep purple crystals, also the most expensive.

Amethysts from Brazil are clearer with large pyramidal crystals.

Amethysts are also found in South Africa, Canada, India, Madagascar, the Urals and France (Auvergne).

Stones whose origin is for all the amethyst

The amethyst from the Greek "amethystos" meaning "which protects from intoxication" is a crystal of the quartz family in the same way as citrine, which it takes care of to give birth to ametrine.

The heated citrine

Some citrines are just heated amethysts. If amethyst is heated, its color varies from purple to yellow, orange, brown or green. The heated citrine has a very yellow color, darker, less translucent, even opaque compared to natural citrine . The majority of commercial citrines are actually heated citrines. They have inclusions, pockets of water containing minerals retained in the stone and which grow inside.

Clear amethysts are also human-tinted to look like Uruguayan amethysts so they can sell for more... so be careful who you buy your minerals from!

My advice, favor small craftsmen, small family businesses more concerned with quality than large online stores on the Internet.


Ametrine stone is a mixture of amethyst and citrine. The word ametrine comes from the words amethyst and citrine, from which we took the first two and the last two syllables respectively. It is a yellow and purple stone. It can have more yellow than purple or vice versa, it depends on the proportion of amethyst for purple and citrine for yellow. Its main origins are Brazil and Bolivia.


These are two-tone stones.


In the trade, the prasiolite that you will find is an amethyst having undergone an alteration of its color to become green. Natural prasiolite is a fine stone also known as prase or green quartz which has an olive green color. This green quartz is extremely rare.

The word Prasiolite comes from the Greek “lithos” which means “stone” and “prason” which means “leek” for the tone of its green. Its color is water green to light green, rarely deep green. Its natural green color is extremely rare, it is obtained most of the time by heat treatment.


The stone that bears the name of amegreen or amergreen is a mixture of amethyst, prasiolite and white quartz. It is uncommon.
