The composition of peridot:

The Mohs hardness of olivine is between 6.5 and 7.0, and its yellow-green color comes from the iron element in it. Volcanic rock (that is, basalt) is rich in magnesium and iron elements, so olivine belongs to the forsterite and fayalite solid solution series, and a large amount of hardened lava slag is the source of olivine. Gemstone species ferrous iron (Fe2+) are known to produce green, while ferric iron (Fe3+) produces yellow, and traces of chromium (Cr) make the green brighter.

The composition of the olivine species is closer to the forsterite side, and the green is more obvious, but if it is closer to the iron-dominated fayalite, its color tends to be yellow and brown.

Types and History of Peridot:

Gem-quality peridot is mainly divided into dark yellow-green peridot, golden yellow-green peridot, yellow-green peridot, dark green peridot (also known as evening primrose emerald) and sky gem (from meteorites and is very rare).

The August birthstone has a rich history. Peridot has been produced on the famous island of St. John in the Red Sea or Zabalgard in Egypt since ancient Egyptian times. The site also produces one of the most confusing name mix-ups in gemology. The ancient Greeks called the island Topazios, and it is said to produce yellow-green gemstones. The island’s name eventually led to the topaz names for those famous (but not limited to) yellow gemstones. Oddly, the gemstone identified by modern gemology as topaz does not appear on this island. However, the gem from the island is also known as chrysanthemum, which means “stone of gold” in Greek. By the 19th century, chrysoberyl, prehnite, and peridot (all green to yellow-green gemstones) were known as chrysoberyls.

In ancient times 3,500 years ago, people discovered peridot on the island of St. John, an ancient Egyptian territory, and called it the “jewel of the sun”. At that time, there were frequent conflicts between tribal forces, and the people suffered unspeakably. Peridot is deeply loved as a symbol of peace. At the same time, peridot and agate are listed together as the “August Birthstone”. We can still see peridot inlaid thousands of years ago in temples in Jerusalem.
