Prehnite History

Prehnite stone belongs to the order of silicates and is quite rare. Very appreciated ornamental stone, it is found in different forms: rough, rolled, flattened pearl, cabochon cut, faceted cut, etc., depending on what you want to do with it (necklaces, bracelets, rings, earrings, small objects ...).

Its name comes from a Dutch commander, Hendrick Von Prehn, who supposedly discovered it in 1774, at the Cape of Good Hope. He brought back several of these minerals and had them analyzed by Abraham Gottlob Werner, a German mineralogist. The latter recognized the stone as a new mineral species. Thus, in 1783, Werner gave it the name "prehnite", in honor of the man he thought he had discovered it.

However, it turned out that the first samples of this stone had already been brought back in 1771 by a French astronomer, Alexis-Marie de Rochon, during a trip to the Southern Lands. Its earliest description had therefore been made by Balthazar Georges Sage. This French mineralogist named it, the same year, "Chrysolite du Cap". But this name is now forbidden.

At the time, this gem was very rare and it was already attributed certain virtues. For the shamans of South Africa, the prehnite stone allowed them to make good decisions, and thus helped them to guide their community. As for the aborigines of Australia, they believed that this stone had the power to absorb and store the energy of the sun, and then redistribute it. They used it at night to keep warm and to repel nocturnal creatures.

Prehnite Origin & Composition

Prehnite stone, containing epidote inclusions (dark or white lines), is composed of calcium silicate, aluminum and sometimes iron. Mainly green to yellow, translucent or semi-transparent, it can also take on grey or milky white tones. It looks a lot like jade. It is sometimes called "yellow jade from Australia", or "grape jade" in China. An even rarer version, orange in color, has been discovered in Canada and South Africa. Because of its color, quality and rarity, this splendid natural stone seduces jewelers and collectors.

This mineral material generally forms in cavities and cracks in eruptive rocks and crystalline shales. We find deposits in several countries of the world: South Africa and India mainly, but also United States, Australia, Mali, France, Italy, Spain, Germany, Switzerland. The prehnite of Mali is one of the most beautiful specimens, thanks to the epidote inclusions it contains.

Moreover, its refractive index is from 1.61 to 1.67. For comparison, the refractive index of the diamond is 2.42. In general, the higher the index, the slower and more deflected the light is, and therefore the brighter the stone. In addition, this stone is biaxial, which means that it has two optical axes. The transmitted light is divided into three directions of vibration. However, it can appear uniaxial (only one optical axis).
