origin of name | “Onion stone” or prasiolite. The person who came up with the name for this mineral clearly has a wonderful imagination. By the way, the first mentions of prasiolite appear in the times of Ancient Greece. The word “prasio” or πράσιος itself is translated from ancient Greek as the color of leek (light green). This interesting resemblance is due to the color of the stone, which resembles the color of a leek. |
Prasiolite is a natural variety of crystalline quartz. This mineral is rare and comes in rich green tones: emerald and onion green, lemon and grassy. Prasiolite is characterized by increased fragility, translucency, glass luster and conchoidal fracture. Under the influence of sunlight, the gem loses its color and turns into rock crystal.
Prasiolite deposits
The first deposits of prasiolite were discovered in Switzerland. To date, its deposits have been found in Brazil, Australia, India, Madagascar, South Africa, and Uruguay. Small mines are developed in Poland, Germany, America, and Russia. Almost all modern mineral deposits have been worked out, and specimens of natural prasiolite are very rare.
History of prasiolite

The term “prasiolite” is translated from Greek as “onion stone”. This name is associated with its hexagonal prismatic crystals, as well as its soft green color, reminiscent of leeks. It was in Ancient Greece that prasiolite was first discovered two thousand years ago. And the Greeks also noticed that in the bright sun its crystals become pale. This phenomenon was explained by the influence of the Gods.
Initially, the name of the mineral sounded like “prasitis”, and only in the middle of the 20th century it was transformed into the modern “prasiolite” and a scientific description was given to the stone. Since natural deposits of this stone are almost completely exhausted today, there are methods for producing artificial prasiolite by calcining amethysts at a temperature of 5000°C.
General description of the stone
Prasiolite is a type of quartz. It got its name thanks to the color. Formed by two ancient Greek words: the first is translated as “light green” or “leek”, the second is “stone”. There are different shades.
The stone is rarely found in nature. Most of the “prasiolites” that go on sale are synthetic crystals or fakes. Sometimes the mineral is also called green amethyst. In fact, these are different stones. A beautiful name helps you sell better.
Synthetic prasiolites are made from amethysts. The stones have a similar structure. When heated strongly, some amethysts take on an onion-like color. Yellowish quartz is also processed. The technology was first tried in 1950 in Brazil.
Main properties of prasiolite:
- transparency - full or partial;
- strength - 7 points on the Mohs scale;
- refraction of light - low;
- shine - dim;
- In the sun, the mineral gradually fades.
Prasiolite stone is easy to cut and polish. Together with its beauty, this makes it a convenient material for jewelry: pendants, necklaces, earrings and more. Sometimes prasiolite is used to imitate more expensive stones. It looks like peridot, tourmaline, beryl.
Prasiolite is mainly used in jewelry. The stone is considered semi-precious and ornamental.

Afraid of the sun
Prasiolite has been produced by calcining mined amethysts since 1950. This requires a temperature of 500 degrees Celsius. Therefore, almost all jewelry that lies on jewelry counters are heat-treated minerals. Most of them are mined in Brazil in the Montezuma mine or in the US state of Arizona.
However, those stones that were obtained by heating and calcination are afraid of sunlight. They fade. The rich bright green color of prasiolite indicates heat treatment and that this is a green amethyst.
If when purchasing you see a light green tint, then you can’t hope that the stone is natural. The number of prasiolites in the world is so limited that it is hardly possible to find it on the open market. Some gemologists generally believe that there is no natural prasiolite.
Where does color come from?
Classic amethysts owe their purple-pink hue to impurities of manganese and iron. Green color in nature is created by pigments of organic origin.
Green amethyst
But this rarely happens, so people have learned to create green amethysts. They are obtained by irradiation or calcination of quartz or amethysts of other colors. Stones from the Brazilian Montezuma deposit or Arizona (USA) are used.
At temperatures up to +500 °C, the final color of amethyst turns out to be onion or light green, lemon yellow, or emerald.
This depends on the chemical composition of the raw materials and the characteristics of the procedure. The resulting material is also called prasiolite or green amethyst.

At the same time, their color changes to green. Even craftsmen in the Urals used a similar method when they baked quartz in loaves of bread and as a result received crystals of pure green color. Residents of India calcined quartz using focused sunlight, for which they even came up with special devices made from lenses and mirrors. It is very difficult to distinguish artificial samples from natural stones even for a specialist. And the only significant difference between them is that the synthetic mineral does not lose color in sunlight.
Deposits and physical properties
What is this stone? The chemical form of the gem is SiO2. It is common to all quartz materials. The stone is not distinguished by luminescent characteristics or the effect of pleochroism. This means that viewing the crystal under different lighting does not change the shade.
Natural stone can be transparent or translucent. According to the Mohs scale, hardness is 7 points. At the same time, the gem is considered fragile. Its properties are comparable to beryl or peridot.
Natural prasiolite is rare. There are several deposits on Earth in which it is mined industrially. They are located in the following countries:
- India. In this country, luxury stones are mined, which have a magical play of different variations of green.
- Brazil. The stones mined in this country are characterized by a strict light green color.
- USA. The largest crystals are mined in this country.
- Russia. In the Primorsky Territory, beautiful crystals are mined, which are characterized by the correct shape. In terms of variety of colors, they are comparable to Indian gems.
According to jewelers, finding natural stones on sale can be very problematic. Crystal deposits are too scarce. Moreover, scientists have long developed a method for producing artificial gems.
To do this, take tsetrin or amethyst and expose it to high temperatures of 5000 degrees Celsius. After which the minerals are exposed to ultraviolet light. As a result, it is possible to obtain a real stone that has the original physical characteristics. It is important to consider that it does not have medicinal or magical properties.

To clean them, use cool running water and a soft cloth. The use of chemical cleaning agents is not recommended.
The first mention and history of the origin of the mineral
Prasiolite stone was used by the ancient Greeks already 2.5 thousand years ago to create unique jewelry.
At that time, it was called “onion stone”, because after losing its bright color under the influence of temperatures, it became similar to a leek. During the Middle Ages, it was believed that prasiolite had the ability to endow the owner with wisdom and insight. This belief still exists today.
One of the most famous jewelry with the mineral is the brooch of Catherine II, which was given to her by the Polish king Stanislaw II August Poniatowski .

The certificate accompanying such a stone must indicate this information, as well as what mineral was used to create it.
The main features that can distinguish prasiolite from a fake are:
- pallor of shades;
- absence of cloudy areas in the structure of the stone;
- natural inclusions in the structure, crystal shape;
- natural heaviness and coolness of the mineral.
Interesting facts about prasiolite
- In the artificial production of prasiolite, even cloudy quartz crystals with uneven color are used. After calcination, all defects are eliminated and as a result the stone becomes clean and beautiful. Natural prasiolites have practically not been found on the jewelry market for the last half century; they have been completely replaced by an artificial substitute. This is due to the fact that the production of prasiolites in industry is not expensive and economically profitable.
- It is popularly believed that if the owner of prasiolite often lies, the stone will quickly become dull and discolored.
Loses color in the sun
But the prasiolite stone was known long before the beautiful legend appeared. This is evidenced by the ancient Greek root, which is the basis of the name of the stone. True, then it was called prasitis - a word that has the same basis and literally means the color of young leeks, the color of fresh greens.
It turns out that two thousand years ago people were already making jewelry from this stone. The comparison with onions is not accidental, since the green mineral almost always has a pure color, without serious inclusions of any other pigments. Under prolonged exposure to the sun, prasiolite loses its saturation, the green color lightens to yellow.
Some gemologists considered the mineral to be green amethyst, since many of the stones' characteristics are similar. This name is used as a trade term for prasiolite.
