Prasiolite

The green amethyst

overview

Naming: The name prasiolite alludes to the characteristic leek-green color: it is derived from the two Greek words for leek ( πράσον, prason ) and stone ( λίθος, lithos ).

Mineral group: Prasiolite is a golden-green, transparent, shiny gemstone from the quartz group. Alternative names are vermarine or green amethyst.

Colour: Treated prasiolite should not be exposed to direct sunlight, otherwise its colour may fade over time.

Special feature: Thanks to its green color, prasiolite resembles peridot or green tourmaline in appearance and can therefore easily be confused with these two gemstones.

Color

Prasiolite is golden-green and transparent. Prasiolite with an attractive, evenly distributed color is particularly sought after.

purity

Prasiolites with high transparency and no visible inclusions are particularly valuable.

carat

Carat is a unit of measurement for the weight of a gemstone (1 carat = 0.2 grams). The weight is very important for the value of a prasiolite. However, the color, clarity and cut also determine the value.

cut

Prasiolite is often faceted because it brings out the gemstone's sparkle.

Prasiolite – natural and treated gemstones

Naturally formed prasiolite is a rarity and is found only in very few deposits.
However, the majority of gemstones available on the market are treated amethysts. If the violet gemstones are heated to temperatures of 500 degrees, their color changes. They usually take on a yellow hue, as is known from citrines. In exceptional cases, the attractive golden green that is typical of prasiolite appears.
The result of the heat treatment cannot be predicted, but the place of origin of the amethysts significantly influences the color they will take on.
