Appearance
Although olivine is usually green, it can also be brown, greenish yellow, or yellow-green. It is clearly transparent, with a glassy sheen and a hardness of 6.5 to 7.0. With such residences, it is the most common and unremarkable igneous mineral.
Geographical Distribution
Granular masses of olivine can be found in volcanic explosions in Arizona and the German Eifel District. Dun Mountain in New Zealand and the corundum deposits in North Carolina are inhabited by Dunite Mountain.
History
Abraham Gottlieb Werner reclassified chrysolite as olivine in 1789 due to the mineral’s typical olive green color (note that the two names are similar). Johann Friedrich August Breithaupt gave the name tephroite to the group’s second member in 1823.
Metaphysical Properties
Olivine stone provides a positive psychological impact that increases confidence in the person. Stress reduction can enable you to recover a resilient spirit and erase any guilt from the past.
Chemical Composition
A group of silicate minerals with the typical chemical composition A2SiO4 are called olivines. In that simplified composition, “A” is often Mg or Fe, however it can also be Ca, Mn, or Ni in some conditions.
Most olivine has a chemical makeup that is in between that of pure forsterite (Mg2SiO4) and pure fayalite (Fe2SiO4).
Uses
- One mineral that isn’t frequently used for industrial purposes is olivine. The majority of olivine is employed as a slag conditioner in metallurgical processes.
- Forsterite, a high-magnesium olivine, is used to blast furnaces to remove impurities from metallic materials and to help form slag.
- Olivine has additionally been applied as a refractory substance. It is a casting sand and is used in the production of refractory brick.
- As opportunity drugs become more readily available and less expensive, both of those purposes are decreasing.
- Gemstone
The mineral known as olivine is also found in the gemstone known as “peridot.” This yellow-green to green gemstone is highly sought-after for use in earrings. The birthstone for the month of August is peridot. Dark olive green and a glossy lime green are the most sought-after colors. The mineral forsterite is represented by these examples because the iron-rich fayalite is primarily brownish, rather than perfect.
The San Carlos Reservation in Arizona is home to the majority of the peridot mined for the arena and used in mass-manufacturing earrings. The source of the peridot is a few basalt flows that include nodules of granular olivine in them. The majority of the stones that are made there are a few carats in size or less, and they frequently contain visible chromite or other mineral crystals. These are lower back to the US in business earrings after being cut in Asia.
