Introduction
I sincerely believe that all peridot gems and jewellery be purchased from suppliers in accordance with the provisions that were acquired in ethical conditions.
Peridot is one of the prettiest of all green gems, occurring in a colour that is the epitome of grass green. Interestingly enough, the name topaz may have initially been applied to Peridot, for it is found on the island of Topazos (Zabargad) in the Red Sea.
History, Legend and Lore
In ancient believes peridot was a gift of Mother Nature to celebrate the annual creation of a new world. National leaders who publicly wore Peridot were in former times thought to be gentle, fair and wise.
In ancient times and Middle Ages, it was believed that the cosmos is made from precious stones and that Peridot was the planet Saturn. The esoteric movement revived the ancient belief and so the stone industry used it as another marketing tool to promote certain gems.
The green stone, was called Topaz first, and this name remained until the 18th century when the English began to describe the gemstone as peridot. Today, the gem variety of forsterite olivine and the group still bears that name.
Like other gems, Peridot was believed to offer special powers to the wearer. Marbodei mentioned in De Lapidibus that Peridot would dispel the terrors of the night: "If it were to be used as a protection from the wiles of evil spirits, the stone had to be pierced and strung on the hair of an ass and then attached to the left arm." In the Middle Ages, the belief persisted that Peridot would dissolve enchantments and put evil spirits to flight.
Although no records survive, significant work must have taken place during the 11th and 12th centuries. Christian crusaders are known to have returned home with large Peridots as part of their loot. Fine gems from these mines remain today in a number of European sanctuaries including the Treasury of the Three Magi in Cologne and the Vatican. The precious stone and jewelry collection in the Tower of London also contains large peridot gems.
In the early 1900s new Peridot crystals began to appear in European mineral collections, and fine faceted stones were once again offered for sale by important jewelers. Turkish rulers of Egypt apparently directed a series of successful mining ventures until 1922, when the Red Sea Mining Company acquired a lease and located new sources of the gem material. Ismalum Bey, managing director of the company, sold history's largest peridot crystal-actually only a crystal half-to Cairo businessman Max Ismalun. Measuring 6.6 by 5.1 by 2.5 centimeters, the well formed, nearly flawless specimen, as fine deep green colour. Ismalun took the crystal to London and sold it for $100 to the British Museum of Natural History, where it may be seen today. The Red Sea Mining Company abandoned its operation with the outbreak of World War II, and since that time the Peridot deposit has been worked only sporadically. For the past 20 years, it has been abandoned.
Mineralogists know that a large olivine crystals initially formed in cracks that the depth of 25 meters which became the foundation stone of the country, peridotite. Poorly connected to the walls crack, the crystals may have been free from seismic activity or poor weather, after which he fell to the bottom of the slot, where the miners were mixed with the rubble of crushed stone. Although the crystal faces are clean and bright, often with fresh fractures, the theory that the earthquake damage.
Peridot is found in a number of localities around the world, but large gem crystals are unique to Zabargad. Crystals most often are flattened and tabular in form. Doubly terminated examples are very rare. The name Peridot is used to describe the gem variety of the forsterite to fayalite olivine series.

The purchase of Peridot Jewellery
When you buy a peridot are several factors to consider - These are the four Cs - colour, clarity, cut and carat weight.
Colour
Peridot is ideochromatic be coloured by ferrous iron, which is central to its composition. The ideal colour is a deep green grass, but some Peridot is a yellow-green, greenish brown or yellow. The best colours peridot usually contain 10-15% iron.
Forsterite-fayalite series is peridot mineral, which is part of the group of olivine. This is one of the "idiochromatic" gems, meaning its colour comes from the basic chemical composition of the mineral itself, not by small impurities, and then only found in shades of green. Why, in fact, Peridot is one of the few gemstones are found in only one colour.
*Hue refers to the Peridot's basic colour. *Saturation (also called colour purity and intensity) is the extent to which the hue is masked by other colours. *Tone refers to the amount of colour in the Peridot ranging from very light to very dark.
Clarity
Since Peridot is not a particularly expensive stone, eye-clean clarity is the standard. Burmese gems are often marred by small platelet inclusions, which may give some stones a sleepy appearance. The strong birefringence (0.036) of Peridot can also give stones a slightly sleepy look. This is most pronounced in large stones (10 cts. plus).
Clarity, as with all other gemstones, is officially classified as the best in the VVS (very very slightly included) to VS (very slightly included), the SI-S2 (slightly included) and get off at I1, I2, 13 (included).
Cut
Only the imagination limits of cuts and shapes applied to peridot, cuts all great fantasy collapsed beads are seen. Once again, because it is very expensive, the publishers can focus on the beauty of more than the weight of the store. This means that a good cut, proportions and symmetry are expected. Stay away from the deformation of the gems cutting native, unless they are cheap enough to cut a good proportions.
Prices
Peridot ranges in price from about 50-80/ct. well-cut gems in TC 2.1. size to less than 400 to 450 ct. large coloured stone top.
Stone Sizes
Peridot is common in sizes ranging from melee to faceted stones of 10 cts. or more. Fine faceted stones of greater than 300 carats are known, but quite rare.
Sources
Gem Peridot is found in a handful of places around the world. Large sizes (10 pennies. Plus), Mogok Stone tract Pyaung Gaung Burma is the most important. Faceted beads hundreds of carats are known from the deposit. In 1990 a new deposit was discovered in the area of ??Pakistan Suppatt, and this is exactly the same material that Burma.
United States, the San Carlos Apache Indian Reservation supplies good material, but rarely this cut gem above 10 carats. Peridot is also mined in China, Brazil, Australia and Norway, among other places. The story did not deposit Zabargad in every decade.
Improvements
Peridot is not typically enhanced.
Imitations
Peridot has never been synthesized, but a number of imitations exist, including natural stones such as tourmaline, and man-made imitations such as glass. Green glass is the most common imitation, and can be easily separated by its single refraction.
Cleaning Peridot
As with most jewellery, it is rarely necessary to have your jewellery "professionally" cleaned unless they were allowed to become very dirty and / or scratched or damaged. If cleaned regularly enough, so simply by cleaning with hot, soapy water lightly with a very soft toothbrush, all the fire and brilliance original stones remain or be brought back to life. Just be careful.
My last word ..,
No matter where you buy jewellery with peridot, it is certainly better to use a reputable supplier, whether via the Internet or high street.
I strongly suggest you buy peridot jewellery with great attention. Expect to pay more for larger sizes of gems, and remember, at the end of the day, "beauty is in the eye of the beholder." In order to choose the stones you want, not what you are led to believe! What peridot colour, size or shape you choose, be sure to use and enjoy!
