Introduction

In the rugged mountains near Neyshabur (Nishapur), Iran, lies one of the world’s most treasured gemstone deposits. For over 2,000 years, these mines have produced turquoise of such exceptional quality that the robin egg blue or sky-blue colour of the Persian turquoise mined near the modern city of Neyshabur, Iran, has been used as a guiding reference for evaluating turquoise quality. This ancient mining tradition represents not just an industry, but a cultural heritage deeply woven into the fabric of Persian civilisation.

The Neyshabur turquoise mines, situated in the Ali-Mersai Mountain range of Razavi Khorasan Province, have witnessed millennia of human endeavour. Arguably, the world’s finest specimens of turquoise have come from this deposit. The occurrences were already mined by the ancient civilisations, making it one of the oldest continuously operated mines in the world. The mine has been active for approximately 7,000 years, although modern archaeological evidence suggests that significant mining activity began around the 10th century CE, with some evidence indicating extraction as early as 2100 BCE.

Traditional Extraction Methods: The Old Ways

The Primitive Approach

Until the mid-20th century, turquoise extraction in Neyshabur remained remarkably unchanged from ancient times. Miners still use traditional methods, chiselling raw turquoise from rugged cliffs—a process unchanged for centuries. Henri René d’Allemagne, who visited the mines in 1907, documented these traditional methods in his travelogue, describing two primary extraction techniques:

Method One: Direct Mining

 The first method involved breaking rock formations directly to extract turquoise. This was an arduous process requiring specialised tools and tremendous physical endurance. Workers would position a long iron rod called a “deyram” (also known as “diram” or “dilam”) against the rock face. A second worker would then strike the rod repeatedly with a heavy iron hammer called a “potk”—essentially an oversized sledgehammer.

The rhythmic pounding created a unique soundscape in the mountains. With each powerful blow, workers would cry out “Ali jan!” (Oh Ali!), while others would respond “Ali zurat bedeh!” (Ali, give you strength!) or “Ali yarat, behtar bezan!” (Ali help you, strike better!). These calls echoed through the mountain valleys, creating a haunting chorus of human struggle against stone.

This method required not only brute strength but considerable skill. In the darkness of the caves, lit only by flickering oil lamps, a single mistimed blow could shatter a worker’s hand. The precision required was extraordinary—workers had to create holes approximately two spans deep in the hard rock face.

Method Two: Reworking Old Sites

 The second method involved searching through previously worked areas and sediments. This approach often proved more productive than direct mining, as workers could sift through tailings and debris to find overlooked turquoise fragments.

Traditional Tools and Equipment

The traditional mining arsenal consisted of several specialised implements:

• Deyram/Diram: A long iron rod used for drilling holes in rock faces
• Potk: A heavy iron hammer, larger than ordinary hammers, used to strike the deyram
• Koleng: A standard pickaxe used for excavating soft earth and breaking smaller stones
• Qarbil: A specialised sieve made from tanned sheepskin stretched over a wooden frame, used to transport extracted material
• Karva: A tin oil lamp with twin wicks, providing the only illumination in the dark tunnels
• Rowqan-dun: Oil containers for lamp fuel
• Anbun: Sheepskin bags converted into carrying sacks for transporting turquoise-bearing stones

The Washing Process (Chal-shuyi)

After extraction, the turquoise-bearing stones underwent a washing process called “chal-shuyi.” This took place in specially constructed pools called “gul” near the mine entrances. The process was both simple and labour-intensive:

Workers would dump the extracted stones into these pools and agitate them with shovels. Then, remarkably, children aged 10-12 would wade into the pools with bare feet, kicking and trampling the stones to reveal turquoise veins. These young workers, earning only 2-3 qiran per day, often suffered injuries to their feet but persevered to help support their families.

During their work, the children would sometimes divide into groups and sing traditional work songs:

“Golla moxam, golla” (I don’t want flowers, flowers) “Doxtara-ye qaragolla” (Girls of black flowers) “Ash ra moxam, ash ra” (I don’t want soup, soup) “Doxtara-ye qazalbash ra” (Girls of the Qizilbash)

Meanwhile, workers in the mines would sing their own verses:

“My heart cannot bear separation Salt has no saltiness in my hands Let me take these saltless hands; And grasp the hem of fortune’s wheel”

Worker Conditions in Traditional Mining

The Human Cost

Traditional mining exacted a severe toll on workers. Most were either unpaid labourers bound to mine operators or poorly compensated day workers. Payment systems were often exploitative—workers received vouchers for goods from designated shops rather than actual wages, creating a system of debt bondage.

Working conditions were brutal. Miners worked without fixed hours, their schedules determined by turquoise discoveries. When finds were abundant, work continued from dawn until late at night. The combination of long hours in dark, humid, poorly ventilated spaces led to numerous health problems:

• “Qara Qabdal”: The most common ailment, characterised by severe stomach pain and vomiting, caused by the strenuous hammering work and heavy lifting
• Respiratory problems: Poor ventilation in the caves led to breathing difficulties
• Frequent colds and chest pains: The extreme temperature variations between the hot, humid mine interiors and cool mountain air caused workers to strip to minimal clothing while working, leading to rapid cooling and muscle strain during breaks

Many workers developed chronic respiratory conditions that progressed to tuberculosis, exacerbated by malnutrition and poor living conditions.

Daily Life and Sustenance

Each morning, workers would pack simple meals—typically bread, dried yogurt, and occasionally halva or “kuki” (a type of fritter). They would then descend into the dark world of the mines, carrying these meagre provisions and their oil lamps.

Management Hierarchy

The traditional mine operation employed several levels of supervision:

• Mobash: The mine operator’s representative, responsible for overall management
• Zabit-bashi: An experienced supervisor who directed operations within the mine and determined excavation sites
• Zabit: Assistant supervisors who monitored workers and enforced productivity, often penalising workers for perceived laziness

Historical accounts describe harsh disciplinary measures, including workers being tied to posts outside the mine entrance for minor infractions.

Historical Wages

Wage records from the late 19th century reveal the economic realities of mining work. Around 1303 AH (1885 CE), daily wages ranged from four to ten shahis. By 1882, average daily wages were approximately 5 qiran for miners and 2 qiran for stone cutters—modest sums even by the standards of the time.

Modern Extraction Methods (Mid-20th Century)

The Transformation

In 1974 (1353 Iranian calendar), the Iranian government assumed direct control of the Neyshabur mines, marking a dramatic transformation in operations. The author of the original text visited the mines during this transition period, documenting the changes from traditional to modern methods.

Contemporary Operations

The modernised mine employed 200 workers and 20 administrative staff under the supervision of a qualified engineer. Workers now receive regular wages ranging from 13 to 40 tomans based on experience and specialisation, along with insurance benefits. Working hours were standardised to seven hours daily, ending at 1 PM.

Safety measures included mandatory metal helmets for all underground workers. The mining process became systematised, with workers organised into teams assigned to specific sections called “pishkar” (work faces), numbered sequentially for identification.

Modern Extraction Process

Controlled Blasting: Explosions were scheduled for late afternoon after the completion of daily work. Qualified personnel determined blast locations and used dynamite in controlled, safe procedures.

Systematic Collection: After extraction, workers sorted turquoise-bearing stones into numbered canvas bags weighing 1-1.5 kilograms. Each bag was sealed and marked with the corresponding work face number.

Quality Control: All bags were weighed and documented on cards, noting date and location, before temporary storage in designated warehouses.

Waste Management: Mine waste was transported via rail cars to designated areas approximately 50 meters from the tunnel entrance. A white chalk line marked the boundary beyond which only authorised personnel could pass, as valuable turquoise pieces might remain hidden in the debris.

The Abdaar Cave

Modern operations focused primarily on the “Abdaar” (water-bearing) cave, which featured extensive rail systems for wagon transport. As the name suggests, this section encountered underground water sources, requiring electric pumps and piping systems to maintain workable conditions.

Mine Traditions and Beliefs

Sacred Rituals

The Neyshabur turquoise mines developed rich traditions over centuries of operation:

Daily Rituals:

• Before entering the mine each morning, workers would gather at the entrance to curse Satan and send blessings (salawat)
• Upon discovering valuable turquoise veins, workers would sacrifice sheep and hold communal meals with religious recitations

Opening New Sections:

• Before opening new work faces, a sheep would be led through the tunnels and then sacrificed
• Workers who survived dangerous falls would celebrate with thanksgiving sacrifices

Rewards: When a work face produced high-quality turquoise, each worker in that section received half a man (approximately 3 kg) of sugar as a bonus.

Spiritual Beliefs

Miners developed elaborate belief systems around their work:

• Sacred Stone: Turquoise was considered a holy stone
• Divine Blessing: Imam Reza’s journey through Khorasan was believed to have blessed the mine with inexhaustible reserves
• Moral Purity: Immoral or impure acts near turquoise would cause the stone to lose its colour
• The Evil Eye: Malevolent gazes could turn turquoise black or white
• Ritual Purity: Workers who were ritually impure would not enter the mine, forgoing that day’s wages

The Messenger Bird

Miners believed in a small, green bird called “kamar goli” (yellow-belted) that served as turquoise’s messenger. When this bird appeared at the mine entrance and sang, it foretold abundant turquoise discoveries.

The Veil of Mystery

When mines produced little turquoise, workers explained that “the veil of the unseen has been drawn over Turquoise Mountain.” Only when this mystical veil lifted would turquoise reveal itself again.

Turquoise Classification and Valuation

Traditional Grading Methods

Historical grading took place at the mine site under the supervision of “aba ba dush-ha” (cloak-wearers)—elderly, trusted experts from the mine village who wore traditional cloaks as symbols of their authority and white-bearded wisdom.

The Friday Ritual

Every Friday, mine operators would host elaborate meals, inviting three or more expert appraisers. After dining, these experts would spread turquoise samples on cloths and conduct detailed evaluations in the presence of supervisors.

The “Zir-Joli” System

The most fascinating aspect of traditional valuation was the “zir-joli” (under cloth) pricing method. Appraisers would place their hands under a cloth and communicate prices through finger signals—a silent auction system that ensured independent valuations:

• Four fingers indicated 400, 4,000, or 40,000 tomans (depending on stone quality)
• Two fingers signified 200 or 2,000 tomans
• The stone’s visible quality eliminated confusion about magnitude

This system served two purposes: it accommodated illiterate appraisers and prevented bias from hearing others’ evaluations. Similar methods were used by pearl traders in the Persian Gulf, though with greater complexity.

Modern Pricing

After evaluation, each turquoise grade was placed in separate bags with price cards sealed inside. Trusted individuals or mine partners then transported these bags to Mashhad for final sale.

Turquoise Types and Categories

Geological Formation

Persian turquoise refers to turquoise gemstones mined in Iran, historically known as Persia. It is prized for its intense, sky-blue to greenish-blue colour, often with intricate veining or matrix patterns, which enhance its beauty. The Neyshabur turquoise forms through complex geological processes in volcanic rocks over millennia.

The stone appears as blue veins or nodules within black host rock, with vein thickness typically measuring only a few millimetres (rarely reaching one centimetre). Vein lengths vary from decimeters to several meters. The estimated volume of turquoise-bearing rock at Neyshabur reaches approximately 10 million cubic meters.

Traditional Categories

After grading, different turquoise types received specific names based on colour, quality, and intended use:

Premium Grades:

• Ajami: Round, large stones with pure, deep blue colour. The highest quality and most expensive type
• Ajami Nim-rang: Lighter-coloured version of Ajami, sometimes artificially enhanced in foreign markets

Commercial Grades:

• Arabi: Flat turquoise popular in Arabian markets, featuring deep blue colour but lower value than Ajami
• Tufal: High-quality thin layers with deep blue colour, processed into “Bab-e Karbala” stones after cutting
• Tufal Nim-rang and Tufal Safid: Progressively lighter versions of Tufal

Specialty Types:

• Chaghale: Large stones similar to Ajami but with pale blue colour and soft composition, difficult to polish properly. Also called “Bab-e Makkah” due to Saudi Arabian market preference
• Shajari: Veined turquoise with patterns resembling tree branches against black or yellow backgrounds
• Shukufe: Smaller stones cut into tear-drop, almond, or flower shapes

Lower Grades:

• Chal/Narm: Small, round stones once popular in America and India for traditional beauty marks and “Bombay rings”
• Dorosht: Large stones with thin, scattered turquoise veins—the lowest grade from Neyshabur

Historical Mine Management

Ancient Operations

Historical evidence suggests significant turquoise extraction during the Safavid period, when the mines gained international recognition under Shah Abbas the Great. One notable concessionaire, Abdul Razzaq, discovered exceptional turquoise in the “Abu Ishaq Cave,” giving his name to the famous “Abdul Razzaqi turquoise” grade still recognised today.

According to legend, the first types of turquoise were introduced into Western culture via the Silk Road, which connected cities such as Neyshabur (Neyshabur), Tous, Damghan, and Baghdad to Asia Minor, Europe. During this period, Neyshabur turquoise reached European markets through Russian trade routes, establishing its global reputation.

Qajar Period Challenges

The 18th century saw reduced government attention to the mines, leaving local villagers to continue extraction with primitive tools. When Prince Hassan Ali Mirza became governor of Khorasan, formal concession systems were reestablished.

The Turbulent Concessionaire

Mining records preserve dramatic stories from the Qajar period, including one particularly notorious mine operator whose harsh treatment sparked worker rebellion. During World War II’s chaos, workers destroyed his facilities and temporarily seized control. His attempted revenge—disguising armed servants as foreign soldiers to raid workers’ homes—backfired when discovered, leading to his eventual departure.

Concession Economics

Historical rental rates reveal the mines’ economic significance:

• Mid-13th century AH: 1,000 tomans annual government revenue
• 1291 AH (1882 CE): Total rental not exceeding 8,000 tomans
• Mokhtabar al-Dowle’s 15-year lease: 9,000 tomans first year, 18,000 tomans thereafter
• Early 14th century AH: 20,000 tomans rental, 60,000 tomans market value
• Lord Curzon (1310 AH): 80,000 tomans actual revenue (£22,850)
• 1943 CE: Final concessionaire’s 10-year lease at 12,000 tomans annually

The last private concession operated until 1974, when the Iranian government assumed direct control, ending centuries of private mine operation.

The Art of Turquoise Cutting

From Rough Stone to Gem

After extraction, artisans in Mashhad and Neyshabur shape these rough gems into polished stones of exceptional beauty. The transformation from raw, black-encrusted rock to brilliant blue gemstone requires extraordinary skill and artistry.

Raw turquoise emerges from the mines as irregular black stones that would merit no second glance if found on a mountain path. The craftsman’s trained eye and skilled hand transform these unpromising specimens into gems worthy of royal jewellery.

The Eight-Stage Process

Turquoise cutting follows a precise eight-stage process, each requiring specialised tools and techniques:

Stage 1: Bab Habba (Initial Breaking)

The most critical stage involves carefully breaking the raw stone to remove excess material while preserving maximum turquoise content. Master craftsmen study each stone carefully before making the first cut, understanding that proper technique here determines the final stone’s value.

Tools:

• Cheft: Plier-like tool (14.5cm handles, 0.5cm thickness, 1.5cm opening) for “meaty” Ajami turquoise with minimal host rock
• Ajenna: Dual-bladed hammer with 31cm wooden handle for stones requiring less delicate treatment

Stage 2: Habba Kardan (Shaping)

After initial breaking, craftsmen remove remaining excess material and irregular edges, beginning to form the stone into a “habba” (grain/bead shape). The stone is wrapped in cloth called “latta-ye kar” and held with three fingers while being shaped against the grinding wheel.

Stage 3: Khom-tarash (Curve Cutting)

This stage refines the stone’s shape while creating smooth curves on the back and sides. The same grinding wheel is used, but with greater precision and attention to symmetry.

Stage 4: Sar-chub Kardan (Mounting)

As the stone becomes too small for finger-holding, it must be mounted on a wooden stick called “lukh” using a special adhesive called “kandal.”

Materials:

• Lukh: Wooden sticks cut from reeds found along the Kashaf River (locally called “darya”/sea), cut into 13.5cm lengths with special scissors (“gaz”)
• Kandal: Adhesive mixture of “gol-e rushuyeh” (pipe clay), “lar” (tree resin), and animal fat, prepared in cylindrical containers (“kandal-dun”) over heat

Stage 5: Qeltundan (Rolling/Rounding)

The most delicate stage, requiring specialised wheels to create the stone’s final curved profile. The curved line around the stone’s perimeter—properly cut, this demonstrates the craftsman’s mastery—is called the “khat-e Farsi” (Persian calligraphy).

Tool: Charkh-e qeltundan (Rolling wheel) made from fine sand and “lak” (lacquer) mixed and moulded into circular forms with multiple concentric grooves called “nahad” for different stone sizes.

Stage 6: Jala Kardan (Polishing)

Using sandpaper wheels, craftsmen remove microscopic imperfections and begin bringing the stone to its characteristic lustre.

Tool: Charkh-e sandpaper – wooden wheel covered with 2-2.5cm thick sponge and 100-180 grit sandpaper, attached via an iron screw to a walnut wood handle.

Stage 7: Bid Zadan (Final Finishing)

The ultimate stage, where the stone receives its final polish and true colour emerges. Even minute flaws (“lak”) become visible at this stage.

Tool: Charkh-e bid – similar to a polishing wheel but covered with chamois leather instead of sandpaper, available in smooth traditional or fuzzy modern versions.

Cutting Equipment

Traditional turquoise cutting employed two types of machinery:

Traditional Bow-Driven Lathes: Operated by hand using a bow (“kaman”) and string (“ze-rud”), these machines gave craftsmen precise control over speed and pressure, crucial for delicate work.

Modern Electric Lathes: While faster, these sometimes lack the subtle control of traditional equipment. Master craftsmen often prefer traditional machines for certain operations.

Supporting Equipment: Each workstation includes a small water bowl (“kashkul”) for keeping stones moist during cutting, as damp turquoise cuts more easily and produces better results.

Cutting Centres

Turquoise shaving is generally performed in three cities: One is in the Firoozeh, which is located in the two Olia and Sofla villages (Upper Village and Lower Village), where most housewives are turquoise women, and the other cities are Neyshabur and Mashhad. This distribution reflects centuries of specialised craft development, with each centre maintaining its distinctive techniques and quality standards.

Cultural and Economic Impact

Global Recognition

Nearby are turquoise mines that have supplied the world with turquoise of the finest and highest quality for millennia. The Neyshabur mines have contributed significantly to global turquoise appreciation, with their products gracing royal collections and religious artifacts across civilisations.

Contemporary Significance

Today, Neyshabur turquoise: Iran’s national gemstone with a history as rich as its colour, renowned globally for its unparalleled quality, continues to represent Persian cultural heritage. Despite modern mining challenges and changing global markets, the tradition endures as both economic activity and cultural practice.

Preservation Challenges

Modern mining faces numerous challenges, including infrastructure limitations, environmental concerns, and competition from synthetic alternatives. Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, and exploration difficulties affecting Iran’s mining sector generally.

Conclusion

The Neyshabur turquoise mines represent far more than a geological phenomenon or industrial operation. They embody thousands of years of human ingenuity, cultural tradition, and artistic excellence. From the ancient miners who first chipped turquoise from mountain faces to contemporary craftsmen who transform rough stones into gems of ethereal beauty, this tradition represents humanity’s enduring relationship with the earth’s hidden treasures.

The techniques, tools, terminology, and cultural practices described in this account preserve invaluable knowledge of traditional mining and craftsmanship. As modernisation continues to transform ancient industries, documenting these practices becomes increasingly important for cultural preservation and historical understanding.

The story of Neyshabur turquoise—from mountain cave to royal crown—illustrates how human skill, patience, and artistic vision can reveal extraordinary beauty in the most unpromising materials. In an age of synthetic alternatives and mass production, the traditional methods and cultural depth surrounding Neyshabur turquoise remind us of the irreplaceable value of authentic craftsmanship and cultural continuity.

Whether examined as industrial history, cultural anthropology, or artistic tradition, the Neyshabur turquoise mines offer profound insights into Persian civilisation and the enduring human quest to transform raw earth into objects of transcendent beauty. Their blue stones, born in geological time and shaped by human hands, continue to bridge the ancient and modern worlds, carrying forward a legacy as enduring as the mountains from which they come.
