Peridot is a deep yellowish-green translucent form of olivine, often known by the name chrysolite. One of the rare gemstones with a single hue is peridot. Mafic and ultramafic rocks found in lava and peridotite xenoliths of the mantle contain peridot. The gem can be found in silica-poor rocks like pallasitic meteorites and volcanic basalt. One of only two gems that have been shown to have developed in the upper mantle rather than the Earth's crust is peridot. Because to its vulnerability to weathering throughout its transition from the deep mantle to the surface, gem-quality peridot is uncommon on Earth's surface. (Mg, Fe)2SiO4 is the formula for peridot. One of the birthstones for the month of August is peridot.One of the few gemstones, peridot, exclusively comes in the shade of olive-green. Nevertheless, the amount of iron in the crystal structure determines the hue and strength of the green, therefore different peridot gems can range in hue from yellow to olive to brownish-green. Peridot occasionally exhibits a pure, medium-dark toned green without a secondary yellow hue or brown mask. Lighter colored diamonds are owing to reduced iron content.
Peridot is a gem that is commonly found in igneous settings. Volcanic action raises these diamonds from the earth's mantle, where they are created, to the surface. There are certain types of meteorites that include peridot as well, but these specimens are often too tiny and too uncommon to be utilized as gemstones. Both a day and a night stone, peridot retains its brilliant color even when exposed to artificial light. It goes by the name "Evening Emerald" as a result. While the final "t" can be pronounced either way, most gem industry experts pronounce the "t" when pronouncing peridot.
Although huge perfect stones are occasionally cut, peridot gems are typically tiny. A popular and reasonably priced gemstone, peridot is utilized in various types of jewelry, including rings, earrings, necklaces, and bracelets. Bracelets and necklaces may also be made using tumbled Peridot beads and cabochons.
Origins
Olivine is a mineral that is very abundant, while Peridot is more scarce as a gem. Peridot's primary sources now are in Pakistan, Burma, Afghanistan, China, Vietnam, Ethiopia, and the United States, as opposed to ancient Egypt, which was its source (Arizona). Sometimes, Hawaii produces peridot that is large enough to be cut into jewels, however the majority of "Hawaiin Peridot" is not truly Hawaiian.
