Asian Gemstone Mining Regions
Asia is the cradle of the gem trade. For thousands of years before European involvement, the gem routes of Asia connected the mines of Myanmar, Sri Lanka, India, Afghanistan, and the Middle East to the jewellery traditions of every major civilisation on Earth. The finest rubies, sapphires, and spinels in the world’s greatest museum and royal collections came from Asian mines. Today, Asia remains the source of the most premium, highest-priced coloured stones in trade, and understanding Asian mining regions is fundamental to understanding where gem value comes from.
Myanmar (Burma): The Crown Jewel of Gem Producing Nations
No country in the world has produced more legendary, high-value gemstones than Myanmar. The Mogok Stone Tract, the Mong Hsu and Monaswa ruby deposits, the Namya jade deposits, the Kyauk Pyat That and Momeik spinel localities, and the gem gravels of Mandalay Division collectively make Myanmar the most prestigious gem-producing nation in the world.
Mogok: The Valley of Rubies
The Mogok Valley in northern Myanmar, about 200 km north of Mandalay, has been mined for rubies, sapphires, spinel, and other gems for at least 1,000 years, and likely much longer. The geology is a complex marble belt metamorphic terrain that produces the low-iron, chromium-rich corundum responsible for the finest rubies known. Mogok pigeon’s blood ruby — pure red with strong UV fluorescence — remains the single most valuable gemstone type per carat weight at auction.
Mogok production has declined from its historical peak, with many superficial deposits exhausted and deeper mining required. The Myanmar government has periodically restricted foreign involvement in gem mining and trade, affecting the flow of Mogok material onto international markets. Political events including the 2021 military coup led to sanctions by Western governments that complicate the sourcing and trading of Burmese gems.
Jade and Jadeite: Hpakant
The Hpakant jade mining area in Kachin State is the world’s primary source of gem-quality jadeite. The scale of Hpakant mining is extraordinary — giant excavators move mountains of rock to find the prize boulders of imperial jade that feed the enormous Chinese market. The Hpakant area also has a troubled history of conflict, environmental damage, and association with illegal drug trade in the region. The ethical sourcing of Burmese jade is a serious concern for responsible jewellery professionals.
Sri Lanka: The Gem Island
Sri Lanka (historically Ceylon) is perhaps the world’s most gemologically diverse island, producing a remarkable range of gem species from the placer gravels of the Ratnapura district and surrounding areas. Blue sapphire, yellow sapphire, padparadscha sapphire, ruby, alexandrite, cat’s eye chrysoberyl, spinel, zircon, moonstone, garnet, tourmaline, and many other gems are produced from the ancient gem gravels.
Ceylon sapphire carries its own trade designation and premium, particularly for the medium blue stones characteristic of the island’s metamorphic sapphires. The low-iron environment of Sri Lankan metamorphic rocks produces sapphires with a different colour character from basaltic sources — lighter, brighter blues in medium tones, and a full spectrum of unusual colours including fine padparadscha and colour-change varieties. Sri Lanka is also the world’s most important source of alexandrite outside Russia.
Afghanistan: Ancient Sources Under Pressure
Afghanistan has been a significant gem source since antiquity. The Badakhshan region in northeastern Afghanistan has been the world’s premier source of lapis lazuli for at least 6,000 years — the same mines supplied lapis to ancient Egypt, Mesopotamia, and the Renaissance painters who ground it into ultramarine pigment. Afghan lapis from the Sar-e-Sang locality remains the finest in the world, characterised by intense, pure blue with minimal white calcite veining and evenly distributed pyrite.
Afghanistan also produces fine ruby (Jagdalek), emerald (Panjshir Valley), tourmaline (Kunar and Nuristan provinces), and exceptional kunzite and aquamarine from pegmatites in Nuristan. Afghan tourmaline — particularly the fine pink and bi-colour elbaite from the Nuristan pegmatites — is among the most beautiful tourmaline produced globally. The security situation in Afghanistan and the ethical complexities of gem sourcing from conflict-affected areas are serious considerations for professional buyers.
India: Historical Significance and Modern Production
India’s role in gem history is immense but its current production is relatively modest. The Golconda mines of Andhra Pradesh produced the legendary diamonds of the ancient world — the Koh-i-Noor, the Hope Diamond (before its travel to India), the Regent, the Nizam — before their depletion in the eighteenth century. Kashmir produced the legendary blue sapphires of the late nineteenth and early twentieth centuries; the Padar deposit has seen limited renewed production activity.
Current Indian gem production includes some sapphire from Kashmir (limited), emerald from Rajasthan (Rajsamand district), and various ornamental stones. India is far more significant as a cutting centre than as a mining nation: the Surat diamond cutting industry processes the majority of the world’s diamond rough by volume, and Jaipur is one of the world’s leading coloured stone cutting and trading centres.
China: Jade and Growing Production
China is the world’s largest consumer of jade and a significant producer of nephrite from Hetian (Hotan) in Xinjiang Province. Hetian nephrite — particularly the mutton fat white variety — is among the most prized nephrite in the world and is deeply embedded in Chinese cultural and artistic tradition. China also has ruby, sapphire, and other gem deposits but is primarily significant as the dominant end market for multiple gem categories.
