If you’re not an expert, then when you are buying jewellery with Peridot set inside, it can be an exceedingly difficult task. If you want help, I have made this little guide that will hopefully help you make the right choice for your needs. When you buy jewellery with Peridot, you should consider a combination of peridot colour, clarity, weight and cut. As with all gemstones, there are compromises that must be done, and when you select the type and quality of peridot, it is usually up to your colour choice of Peridot that you find appealing and within budget.

Introduction

I truly 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 most beautiful of all the green gems, you will find a colour that is the epitome of green grass. Oddly, the name topaz may have originally applied to peridot, as found on the island of Topazos (Zabargad) in the Red Sea.

History, Legend and Lore

In early beliefs peridot was a gift from Mother Nature to celebrate the annual creation of a new world. National leaders who publicly wore Peridot were in former times thought to be gentile, reasonable and balanced.

In antiquity and the Middle Ages it was believed that the cosmos was made up of sparkling gemstones, and that Peridot was the planet Saturn. The esoteric movement revived the ancient belief in this and the stone industry therefore used it as another marketing tool to promote certain gems.

The green stone, first called Topaz, to which name remained until the 18th century, when the English began to describe the gemstone peridot. Today, the gem variety of forsterite olivine and the group still bears that name.

Like other gems, Peridot was believed to give significant powers to the wearer. Marbodei mentioned in De Lapidibus that Peridot would relieve 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 commit evil spirits to flight.

The Christian Crusaders are known to have returned home from a large peridot as part of the spoils. Examples from these mines are now in a number of shrines, including the Treasure of the Magi in Cologne and inside the Vatican. Gems and jewellery are also to be found in a collection within the Tower of London.

In early 1900 new olivine crystals began to appear in European collections of minerals and well-cut stones was again offered on the market for sale by jewellers of importance. Red Sea mining gave up its operations with the outbreak of World War II and since then these deposits have only been worked sporadically. For 20 years, it was abandoned.

Mineralogists know that large Peridot crystals initially formed in failing cracks, some of them 25 meters deep, which penetrated the principal country rock, peridotite. Poorly attached to crack walls, the crystals may have been loosened by seismic activity or weathering, after which they tumbled to the bottom of the fissures where miners found them mixed in the rubble of crushed rock. While crystal faces are generally clear and bright, they often show fresh fractures, lending credence to the assumption that seismic shift damaged them.

Peridot has a number of places around the world, but a large rock crystal Zabargad are unique. The crystals are usually flat and the table. Double-ended examples are extraordinarily rare. The name Peridot is used to describe the chain of forsterite fayalite olivine series.

Buying Your 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.

Peridot belongs to the forsterite-fayalite mineral series, which is part of the olivine group. It is one of the “idiochromatic” gems, meaning its colour comes from the basic chemical composition of the mineral itself, not from minor impurities, and therefore will only be found in shades of green. As a matter of fact Peridot is one of the few gemstones found in only one colour.

* Hue refers to the base colour of peridot. * Saturation (also called the colour purity and intensity) is the extent to which the tone is masked by other colours. * Tone is the amount of colour in Peridot ranges from ultra light to extremely dark.

Clarity

Since Peridot is not a particularly expensive stone, eye-clean clarity is the standard. Burmese gems are often marred by minor platelet inclusions, which may cause some stones a sleepy appearance. The strong birefringence (0.036) of Peridot can also provide stones a somewhat sleepy look. This is most pronounced in large stones (10cts plus).

The clarity, as with all other gemstones, is officially classified as ranging from the best VVS (very, very, slightly included), to VS (very, slightly included), SI-S2 (slightly included), and down to I1,I2,13 (included).

Cut

Only imagination limits the cuts and shapes applied to Peridot, with everything from stunning fantasy cuts to tumbled beads being seen. Again, because it is not terribly expensive, cutters can focus on beauty more than weight retention. This means that good cutting, proportions and symmetry is to be expected. Stay away from misshapen native cut gems, unless they are cheap enough to cut to generous proportions.

Prices

Peridot ranges in price from about 50-80 for good sized gems per carat, to 400 to 450 per carat for large and well coloured stones, in top condition.

Stone Size

Peridot is common in sizes ranging from mixed faceted stones of 10 carats or more. Fine faceted stones of over 300 carats are known but rare.

Sources

Gem Peridot has been found in a handful of places around the world. In large sizes (10 cts plus), Pyaung Gaung in Burma’s Mogok Stone Tract is most prominent. Faceted gems of hundreds of carats are known from this deposit. In the 1990s, a new deposit from Pakistans Suppatt area was discovered, and this material is every bit the equal of that from Burma.

The United States provides gems from the San Carlos Apache Indian Reservation, but this is rarely cut gems over 10 carats. The peridot is also mined in China, Brazil, Australia and Norway, among other places. The deposit history of Zabargad has not been repeated at all for decades.

Enhancements

Peridot is usually best without.

Imitations

Peridot has never been synthesized, but a number of imitations exist, including natural stones such as tourmaline, and simulated imitations such as glass. Green glass is the most popular copy 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 acutely dirty and / or scratched or damaged. If cleaned regularly enough, so simply by cleaning with hot, soapy water lightly with a supremely soft toothbrush, all the fire and brilliance original stones remain or be brought back to life. Just be careful.

My Last Words..,

No matter where you purchase your Peridot Rings and other Peridot Jewellery from, it is clearly better to use reputable suppliers, whether it be internet, or high street based.

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!
