Appearance
Actinolite is a transparent gemstone that ranges in color from green to black and can occasionally exhibit a “cat’s eye” look. Like tremolite, this fibrous amphibole mineral frequently crystallizes into glassy, flattened prisms.
Geographical Distribution
Actinolite can be found in the following locations: Norway: From Zermatt in the Swiss canton of Valais. At Arendal and Snarum. In igneous and metamorphic rocks, it might take the form of massive, fibrous, or columnar tendencies.
History
Although the exact discoverer of actinolite is unknown, the name was allegedly given to it in 1794 by the eccentric Irish geologist Richard Kirwan.
In actuality, “actinolite” was a translation of the German word “strahlstein,” which can mean either “jet stone” or “radiated stone,” depending on the translator. Remarkably, the word “strahlstein” also denotes “strong” or “masculine.”
The descriptions of actinolite (and other minerals) in Kirwan’s 1794 book Elements of Mineralogy were crucial in establishing mineralogy as a respectable science, even though it’s not totally certain if he was the first.
In 1797, the French mineralogist René Just Haüy, known as the “Father of Modern Crystallography,” named the class of minerals “amphibole.” Actinolite, tremolite, tourmaline, and hornblende are among its components, and their varying qualities and appearances led to the name’s Greek origin, amphibolos, which means “ambiguous.”
Metaphysical Properties
Actinolite relieves intense tension and heart strain while also nourishing the individual. This stone protects the wearer’s emotional body and aura from harmful energy and negativity.
Composition
Actinolite is a mineral with the chemical formula Ca2(Mg,Fe)5Si8O22(OH)2 and belongs to a group of minerals that have varied concentrations of calcium, magnesium, iron, and aluminum. The Mg end is tremolite, the Fe end is ferro actinolite, and actinolite is in the center. Rarely do actinolite have more than 50% Fe. There is a substance known as cat’s eye actinolite; when cut, it displays a fine eye.
Uses
- Actinolite is a mineral that is used in jewelry, decorative stones, and gemstones, among other applications.
- Due to its qualities being comparable to those of asbestos fibers, actinolite is frequently employed in industrial applications, such as the manufacturing of asbestos.
- It is occasionally utilized as a gemstone. Certain actinolite varieties are scarce, drawing the interest of certain collectors.
