Panjshir emerald

The emerald country lies on the southern slopes of the Hindu Kush, south of the Panjshir river, in a belt about sixteen kilometres long and three wide that runs north-east from the village of Khenj, 115 kilometres from Kabul by road, at 2,000 to 4,000 metres. The mines the trade names are Khenj itself, Mikeni, Darkhenj, Butak, Buzmal, Bakhi, Darun and Rewat; in 1977 six were active and the road ended at Buzmal, at about 3,000 metres. Miners have always said the best colour comes from Mikeni and Darkhenj. Panjshir became a province in 2004, carved out of Parwan, which is why older papers file the mines under Parwan or Kapisa.

The emerald grows in thin quartz and ankerite veins, up to fifteen centimetres thick, cutting metamorphosed limestone, slate and schist, with pyrite as the miners' indicator mineral. The modern reading is that the stones formed about 23 million years ago, in the Oligocene, at around 400 degrees, from salty fluids that had leached ancient evaporites: the same kind of fluid that made the emeralds of Colombia, but at a higher temperature and in metamorphic rock rather than black shale. That shared chemistry is why Panjshir stones can look so like Colombian ones, and why the laboratories had to learn to tell them apart.

Mining is by hand and dynamite. In 1985 about a thousand men worked the valley, a hundred of them at Buzmal, following the veins in pits and tunnels a few metres deep. A satellite study published in 2022 found the workings becoming more concentrated and shifting from tunnels to mechanised surface excavation.

Under the loupe Panjshir emerald is a classic emerald: a refractive index of about 1.578 to 1.585, a specific gravity of 2.71, inert to ultraviolet, with the chromium lines in the spectrum. Its colour comes from chromium and vanadium in roughly equal measure, with more iron than Colombian stone and the highest scandium the GIA has measured in any emerald. The colour is a rich green with a blue cast, deepening from core to rim, and the crystals cut cleaner and larger than Pakistan's Swat emeralds from across the border.

What tells a laboratory it is from Panjshir are the inclusions and the chemistry together. GIA's 2014 study found elongated, needle-shaped multiphase inclusions more often than the jagged three-phase inclusions typical of Colombia, often holding several small transparent crystals, which Colombian stones do not. SSEF describes spiky, salt-bearing multiphase inclusions, a weak absorption band in the near infrared that most Colombian stones lack, and iron that outweighs the chromium and vanadium. Plots of lithium against caesium, or sodium against scandium, separate Panjshir from Colombia and from Davdar in China. GIA, SSEF and Gübelin all issue origin reports naming Afghanistan, which they do not do for Nuristan's tourmaline or kunzite.

Between 2017 and 2021 the Swiss laboratories saw a second kind of stone sold as Panjshir: more than a hundred emeralds of one to thirty carats and more that matched the finest Muzo material in colour, inclusions and chemistry, lacking only Colombia's gota de aceite texture and carrying a little more iron. Some had been sold as Colombian. By the end of 2021 at least part of that parcel was believed to be from Musakashi in Zambia instead. For a Panjshir emerald of any value, a current origin report from one of the three laboratories is worth its fee.

Most faceted Panjshir emeralds are under five carats. Crystals of more than 120 grams and cut stones over 85 carats have been tested, a 190 carat crystal came out of Buzmal in 1985, and one American cutting house works Panjshir rough from one millimetre melee up to 70 carat stones.

Nearly every emerald sold is clarity enhanced, and Panjshir is no exception: of a 15,000 carat Afghan parcel examined in 2016, only four stones needed no filling. The fissures that reach the surface are filled with cedar oil, paraffin or a resin such as Opticon or ExCel, which hides them and improves the look. The laboratories grade the degree rather than the substance: GIA writes minor, moderate or significant, sometimes as F1, F2 and F3, and the other laboratories use the same four-step scale from none to significant. Report wording on Afghan stones at auction in recent years has read minor traditional clarity enhancement of an organic variety, moderate amount of oil and resin in fissures, and indications of minor clarity enhancement.

The degree moves the price. The gap between a treated and an untreated emerald of the same look has been put at 20 to 100 per cent, and a certified unenhanced stone at about half as much again. Resin is less welcome than oil because it is harder to remove and reverse. Ask for the degree in writing and for the filler if the laboratory names it.

The imitations in the regional trade are dyed green beryl, synthetic emerald, and synthetic crystals glued into natural rock; GIA's 2025 field report from Pakistan's markets found dyed emerald sold undisclosed and advised buyers to suspect alteration unless it is proved otherwise.

For forty years the rough walked out. In the 1980s it went twenty days on foot to the refugee camps and tribal areas around Peshawar, and from Namak Mandi, where Afghan traders made most of the sales, to Karachi, Bangkok and Tucson; in Kabul the dealers of Chicken Street graded parcels for buyers who cut in India, Sri Lanka or Thailand; and a great deal went quietly to Dubai, where a Panjshir house now mines, cuts and sells its own stones. The recorded exports of all Afghan precious stones were about 8 million US dollars in 2024; the real emerald trade has been put far higher.

Since August 2023 the stones are sold at weekly auctions in Bazarak run by the provincial mines department. Licensed miners consign the rough, buyers bid by the lot, and the stones are released when a ten per cent levy is paid, with the rest to the miners. The buyers named in the reports are mostly from the United Arab Emirates, India, Iran and Thailand, with a few foreign traders at each sale and some three hundred traders at a sale in August 2026. A Kabul dealer told the New York Times he missed the days when buyers came from the United States, Britain, France and Germany. Our account of how the Afghan trade works, and the auctions in our own province, is on the buying guide and the auctions page.

For a buyer abroad the law is the same as for any Afghan stone. The United Kingdom and the European Union have no ban and charge no duty on emerald under tariff heading 7103; the United States allows commercial imports under General License 20 but has not said whether the ten per cent auction levy is a fee relating to a luxury item, so a US buyer needs counsel. Emerald's one advantage over Nuristan's stones is that its origin can be proved: a report that says Afghanistan is a report that says the money went where the seller claims.
