Just as they have for over 7000 years, miners employ traditional artisanal techniques alongside modern innovations in pursuit of the world’s oldest continuous source of turquoise stone.

 

Material from any area where the ancient Persian empire once stood can be considered Persian turquoise. In modern times, some dealers also use it as a descriptor for the best quality blue turquoise gemstone. “Persian blue” is typically the most expensive turquoise gem you’ll find.

Persian turquoise may also be called Neyshabur turquoise, named for the locality in which it’s found. The mines are nestled near the city of Nishabur. Named for Shabur I, the second king of the Sassanian Empire, his name combines the Persian words for ‘son’ and ‘king,’ literally translating to “king’s son.”

In the Ancient World, Nishabur was an essential stop along the fabled Silk Road. From here, turquoise gems would make their way to both Europe and Asia. The nature of this trade route allowed communities to specialize in their wares deeply. The people of this region specialized in Persian turquoise, due to the proximity of the mine. They lead the world in quality turquoise for centuries, without peer. In modern times, only turquoise from the American Southwest compares in quality.

The Ancient Persians considered turquoise to be precious, and to them, its intense blue colored reflected the concept of “heaven on earth.” The domes of their palaces would be covered in turquoise to reflect this belief. This ideal color reflects the hue found at the very top of the sky, known as ‘samt al-ras.’

Determining Neyshabur Turquoise Value

Is Persian turquoise valuable? The value of colored stones is typically determined by a combination of its color, clarity, cut, and carat weight. This is no different when determining what Neyshabur turquoise is worth. These guidelines will help you choose turquoise stones for your collection.

The surface of your stone should have an even surface after polishing. Minor blemishes may be present where turquoise stone intersects with pyrite material.

  • Neyshabur Turquoise Cut

Neyshabur Turquoise Treatment

Treatments are techniques used to increase the durability and beauty of a stone that otherwise may not be suitable for use. Most rough turquoise has a chalky and porous quality when it comes out of the ground. Typically, less than five-percent of turquoise is ready for shaping without treatment.

Who Can Wear Neyshabur Turquoise?

Turquoise continues to be among the most coveted gemstones. For centuries, turquoise was a stone many aspired to own. In the Arabic world, turquoise is a stone of prestige. Ancient Persians classified these stones into three grades. The ideal stone during these times was an even blue color, free of matrix. The modern equivalent would be Sleeping Beauty turquoise.

How Does Neyshabur Turquoise Compare to Other Turquoise Stones?

Often, it’s difficult to establish a stone’s provenance by appearance alone. Many visual cues can be altered by treatment, and even thorough testing doesn’t necessarily confirm the origin of a gemstone.

While turquoise faces many of these same issues, the appearance of a stone often provides clues to its origin. The color, saturation, and tone of a turquoise gem give insight on where it came from, in addition to factors such as the host rock in its matrix.

Where Does Persian Turquoise Come From?

Ancient Persia, now modern Iran, is one of the sources of precious turquoise. It is the most significant source of Persian turquoise. Shop LC sources our supply of Neyshabur turquoise from mines located in the Binauld Mountains, near Nishabur, Iran. The mines themselves are based around the village of Firoozeh, about 30 miles northwest of Neyshabur. Notably, Firoozeh is named for turquoise in the Farsi language, owing to its significance to the way of life for people here.

How is Neyshabur Turquoise Mined?

For 7000 years, turquoise mining operations of some sort have existed in Nishabur. Modern miners continue to use the artisanal techniques of their forebears, in addition to newer tools such as dynamite.

Though dynamite makes the mining process more efficient, blasting turquoise-bearing rock can also damage the total yield. For this reason, government bodies are exploring ways to modernize mining methods. Besides, current export regulations reduce the amount of rough that can leave the country. There is a great deal of concern about lost profits from damaging the viable rough material and modernizing the mining and export process to compete on a global scale.

Currents estimates suggest that between 40 to 50 tonnes of rough turquoise leave the country each year. Experts believe that at these levels of production, the mine has enough material to continue producing for 200 more years.

Rough turquoise is then pre-shaped by local artisans. Pre-shaping is the process of roughly forming a stone into a mockup of its final polished shape. Over 300 workshops deal in working with Persian turquoise in the Khorasan Province. Despite this, fewer than 25 turquoise masters remain. These are experts who exclusively deal in turquoise.

Shop LC finishes the process with its expert lapidary team. Stones undergo additional shaping and polishing before finally being set in gorgeous Neyshabur turquoise jewelry.

Persian Turquoise Properties

What Does Neyshabur Turquoise Mean?

As one of the earliest gemstones known to humanity, people have built an impressive body of lore around this amazing stone.

Persian turquoise continues to be held in high-esteem by Arabic cultures. Since antiquity, their culture has employed many methods of describing color grade and stone quality. By the 18th to 19th century, three primary categories emerged to be widely recognized.

  • Angushtari was considered to be the top-grade and was prized for use in turquoise rings. Stones were reviewed on an individual basis, with many tiny qualities setting one apart from another. The slightest deviation in quality drastically lowers its value.
  • Barkhaneh was the middle-grade material; itself divided into four separate sub-categories. Artisans would use this material for inlay and other jewelry, or it was traded to Europeans for jewelry use.
  • Arabi is the final grade of Ancient Persian turquoise. Also subdivided by variations of color or blemish, these stones were used in large items such as amulets and bracelets.

Persian turquoise is also considered to be a “horse stone” by many nomadic cultures. Wearing a turquoise was thought to prevent one from falling or being thrown by a horse. They were also believed to keep horses healthy and calm. Even today, horse tack is frequently decorated with turquoise stones to continue this tradition.

In Ancient Persian culture, turquoise stone was heavily associated with the eye. Besides dispelling the ‘evil eye,’ these rocks were also thought to cure ailments of the eye. Merely carrying a turquoise was said to sharpen eyesight. Besides that, placing a turquoise against the eye would reduce inflammation, and even heal an injury.

The purity of color was held in high-esteem by Ancient Persians. There are several superstitions associated with stones turning color.

In the first, a woman’s faithfulness could be measured by her jewelry. Turquoise would remain bright and blue when she was loyal. If she were to stray, the jewelry would fade.

On the other hand, the stone was thought to indicate general health. When full of energy and vigor, your turquoise gem would remain vibrant. However, if your health were to decline, your turquoise stone would crack and fade.

Finally, Persian turquoise was supposedly a signifier of air purity. The rock would be bright when the air was pure and grow dim when the wind was polluted.

If exposed to the light of a New Moon, a turquoise gem would become infused with luck, bringing many good things to its owner.

Modern gem therapists continue to value turquoise. They credit the stone with treating infections of the throat and lungs. Crystal healers tout its ability to cure diseases and reduce inflammation, especially inflammation of the eyes. On the spiritual side, turquoise combats feelings of depression and promotes self-confidence.

Is Persian Turquoise a Birthstone?

Turquoise has stood the test of time, retaining its popularity over the centuries. Since at least the 15th century, and perhaps even earlier, turquoise has been a birthstone of some sort.

In modern tradition, Neyshabur turquoise is a birthstone for December. It stands alongside tanzanite and zircon as a symbol of this winter month.

Turquoise is also a traditional gift for the 11th wedding anniversary.
