Afghan ruby

The Jegdalek deposit lies in the southern part of Sorobi district, about 60 kilometres east-south-east of Kabul as the crow flies and four to six hours by road, with the workings between 1,550 and 2,000 metres. The ruby grows in beds of almost pure calcite marble hundreds of metres thick and up to eight kilometres long, cut by granite dikes of the Laghman complex about thirty million years old, the same granites whose pegmatites give Nuristan its tourmaline. Some twenty named workings and more than two thousand pits spread across an area the Afghan press puts at fifteen square kilometres; the sub-localities include Lal-Poor, Chongay, Taghar, Warmankai and Mirkalwat, and the Chongay stones run pink and are not the best.

What comes out is mostly not ruby. The GIA's study of 2000 and the British Geological Survey agree on the split: about 75 per cent pink sapphire, 15 per cent ruby, 5 per cent blue sapphire and 5 per cent mixed blue and red crystals, and only about 3 per cent of all the corundum is facetable. Crystals of 174 carats have been seen and good rubies cut to 32 carats, but top-quality stones rarely pass five carats, and the miners' rough is typically semi-transparent pieces of one and a half to three centimetres. Unlike the lapis mines of Badakhshan, Jegdalek can be worked all year.

Jegdalek ruby is a marble-hosted ruby, which puts it in the family of Mogok rather than of Mozambique or Thailand. It is low in iron, so it fluoresces an even medium to strong red under long-wave ultraviolet light, the glow that gives the finest Burmese stones their fire, and the best Afghan stones have been called pigeon's blood in the same breath as Mogok's. The GIA's 2000 study measured chromium as the most variable trace element, with titanium, iron, vanadium and gallium behind it.

Under the loupe the stones carry dense healed and unhealed fractures with a frosted texture, twin planes, and crystals of calcite, apatite, zircon, mica, graphite, rutile and iron sulphides, the sulphides lining the fractures and twin planes. Colour zoning is common, and the most striking feature, reported by every study since 1985, is a strong blue zoning in some rubies: red or pink stones with blue cores, bands or patches, which no other major source shows in unheated stone. The GIA's 2019 origin work describes fine rutile needles and fine particulate clouds in angular or hexagonal patterns in Afghan rubies, distinct from the milky clouds of Vietnam and the coarser silk of Mogok. Laboratories including Lotus Gemology in Bangkok issue reports naming Afghanistan as origin; so, for ruby, does GIA. Aluminium hydroxide in the infrared spectrum tells a laboratory the stone has not been heated.

Stones bought at the mine are unheated; much of what is sold onward is not. Heating deepens and evens the red, and lead-glass filling, which fills the fractures with high-lead glass, turns heavily cracked low-grade corundum into something that photographs like ruby and is worth a few dollars a carat. Glass filling shows gas bubbles, blue or orange flashes in the filled fractures and flow structures under the loupe, and a laboratory finds the lead at once and reports the stone as a ruby-glass composite. Soldiers and travellers buying rubies in Afghan bazaars have, by the forums' consensus, mostly bought glass-filled African stone worth about ten dollars a carat.

The fakes go further than treatment. GIA's Winter 2025 field report from Pakistan's markets found a ruby sold in Namak Mandi as Jegdalek that was a synthetic crystal set into natural rock, a 77 carat parcel labelled natural Jegdalek ruby that mixed unheated, heated, glass-filled and synthetic stones, and marble specimens glued together with resin; its advice was to suspect alteration unless it is proved otherwise, and to put no weight on the words from the mine. For Afghan ruby of any value that means a laboratory report, and for a specimen on matrix a close look at the join.

Most Jegdalek corundum is sold in Peshawar and goes on to Karachi and New Delhi, with about five per cent of the lower grades taken to India through Kabul and some reaching the Thai market; sorting and much of the heating happen outside Afghanistan, and a stone sold in Bangkok as Afghan may have been there for years. Since the 2024 contract the mine's output is, on paper, the company's and the state's, with the 44 per cent share to the treasury; how much still leaves the old way is not known.

The law for a buyer abroad is the same as for every Afghan stone, with one point in ruby's favour. Burmese ruby has been barred from the United States twice, under the 2008 JADE Act and, since April 2021, through sanctions on Myanmar's state gem enterprise that effectively ban Burmese gems again; Afghan ruby is not affected, enters the United States free of duty under heading 7103.91, and is admitted commercially under the Afghanistan general licence with the conditions explained in our buying guide. The United Kingdom and the European Union have no ban on Afghan goods and charge no duty on ruby.
