Kunar is a province in eastern Afghanistan, on the Pakistan border opposite Pakistan's Khyber Pakhtunkhwa Province, and one of the most productive pegmatite gemstone regions in the world. The provincial capital is Asadabad. The Kunar valley extends north-east from the Kabul-Jalalabad road into the Hindu Kush, and the province takes in a series of granitic pegmatite belts that produce tourmaline, kunzite, hiddenite, aquamarine, morganite, beryl in other colours, topaz, fluorite and a long tail of minor pegmatite minerals.

Geology

Kunar's gem-bearing pegmatites occur within the Nuristan pegmatite province, a major LCT-type (lithium-caesium-tantalum) field that extends north into Nuristan Province and east across the Pakistan border into Chitral and Bajaur. The host pegmatites are products of late Miocene to Pliocene granitic magmatism associated with the Indo-Eurasian collision. Deposits are typically zoned, with quartz-feldspar walls grading inward to lithium-rich pockets containing tourmaline, spodumene, lepidolite and beryl.

Production

Tourmaline is the most consistent commercial product of Kunar, with elbaite varieties spanning nearly the full colour range: pink, red, green, blue, parti-coloured (watermelon), and indicolite. Kunzite (lithium-bearing spodumene with manganese chromophore) reaches large sizes; pieces over 100 carats are not unusual, and the deposit has produced some of the largest gem-quality kunzites known. Aquamarine, morganite, and yellow heliodor are also recovered, alongside topaz and fluorite. Output is generally artisanal, with small-scale teams working open pits and short adits during the favourable summer months.

Trade and security

Production reaches the international market chiefly through Peshawar (Pakistan), Kabul, and Bangkok. Security and political conditions in eastern Afghanistan have been periodically difficult, especially since 2001, and supply has fluctuated with regional politics. Material is generally sold through Pakistani brokers in Peshawar and increasingly online through Pakistani and Chinese trade portals. Origin documentation is rare; Afghan or Kunar on a parcel ticket is a trade descriptor based on dealer attribution rather than independent laboratory evidence.

Significance

For the gem trade, Kunar is significant as one of the few sources of fine kunzite in commercial size, alongside Brazil and the United States, and as a long-running supplier of bicolour and watermelon tourmaline. The province's pegmatites are geologically continuous with those of Nuristan and with the Pakistani side of the border in Chitral and Bajaur, and material from any of these adjacent districts is often pooled and traded as Afghan or Pakistani in the international market.
