The origins of the name Peridot are uncertain, though some believe the word peridot comes from the Arabic “faridat”, which means “gem”. Most peridot formed deep inside the earth, over 500 million years ago and was delivered to the surface by volcanoes. Some also came to earth in meteorites, but this extraterrestrial peridot is extremely rare.

Early records indicate that the ancient Egyptians mined a beautiful green gem on an island in the Red Sea, now known as St John’s Island or Zabargad. From the earliest times, people have confused this stone—now known to be peridot—with other gems.      

Some historians believe that Cleopatra’s famous emerald collection may have been peridot. People in medieval times continued to confuse peridot with emerald. For centuries, people believed the fabulous 200-ct. gems adorning the shrine of the Three Holy Kings in Germany’s Cologne Cathedral were emeralds. They are, in fact, peridots.      

In times of peace, peridot was also known as the "stone of happiness", and more importantly, nowadays it is used to celebrate the 16th wedding anniversary.

Peridot belongs to the mineral species Olivine. Peridot’s chemical composition includes iron and magnesium, and it is the iron content that creates the yellowish green colors. The gem occurs in the earth’s upper mantle, in volcanic rocks called basalts, which are rich in these two elements.

Peridot has an extremely high double refraction – when you look closely through the gem, you can see two of each pavilion facet. Fuli prides itself on its exceptional cutting techniques and ensures that each facet optimizes the double refraction of the gemstones.

High Quality Mineral Resource

An external audit was conducted to appraise the quality of the peridot gemstones from the Yiqisong Nanshan peridot mine. The report concluded, that, different from the common yellow-green peridot found in other geographical production areas available in the market, the gems produced by the mine, are characteristically vibrant grass green with exceptional hue and saturation. In addition, they have excellent clarity with no cracks or flaws. Their high-grade and large-carat size make them extremely desirable on the international market.

The most valuable peridot gemstones are those that are a pure green.

Natural peridot often contains black solid inclusions or gas-liquid inclusions. The existence of inclusions directly affects the quality evaluation of peridot. Among them, peridot with "no inclusions or cracks" is the best quality, followed by peridot with "colorless or light green transparent solid inclusions", and peridot with "black opaque solid inclusions and lots of cracks" is extremely inferior and generally cannot be processed and utilized.

Peridot is pre-formed on a lapidary wheel and then the facets are added afterwards. It is the original shape of the rough gemstone that will dictate its final form. Peridot can be cut in many different shapes including octagons, rounds, pears, baguettes & trillions. Fuli aims for perfection with its cutting, ensuring symmetry and brilliance, some Fuli gemstones contain over 110 facets.

Large specimens of peridot are rare and a typical semi-finished product is usually less than 3cts. Peridot of 3-10cts are of higher value because of their rarity. Peridot gemstones exceeding 10cts are extremely rare in nature and are highly sought after. According to records, there are very few incredible specimens of peridot in the world; one from the Red Sea, which weighs 310cts and one from Myanmar which weighs 289cts, both are extraordinary treasures.
