Early sapphire mining techniques under the Maharaja’s control were rudimentary but effective, with guards restricting access to these treasures.
What makes Kashmir sapphires worth your pursuit is their distinctive cornflower blue color with that unmistakable velvety appearance—often described as the “peacock’s neck” hue.
With primary deposits exhausted for over a century, these gems fetch millions at auction. Their extreme rarity guarantees you’re investing in one of gemology’s most coveted treasures.
The harsh environmental conditions limited mining operations to only three-month summer periods, making the extraction of these precious stones even more challenging.
Ancient Sanskrit texts reveal that sapphires and other corundum gems were believed to possess supernatural powers connected to planetary influences, with sapphires specifically linked to Saturn.
Sri Lanka’s Gem Island
While Kashmir represents the pinnacle of sapphire mining history, Sri Lanka stands as Earth’s most concentrated gemstone repository. With 25% of its landmass containing gem deposits, you’ll find unparalleled geological richness across the 6,000-square-mile Highland Group.
When visiting Ratnapura heritage sites, observe how gem mining employs traditional pit-head and tunneling methods that maximize rural employment while minimizing environmental impact. The country’s unique weathering processes have created secondary deposits where sapphire crystals are found in gravel-like structures along riverbeds.
These sustainable practices feature small cooperatives of 3-8 miners working manual operations instead of heavy machinery.
Gemstone regulations through the NGJA guarantee mining communities receive proper benefits while maintaining Sri Lanka’s sapphire significance in global markets.
The island’s approach balances resource extraction with ecological protection, allowing you to witness mining traditions that have remained largely unchanged for centuries, particularly in the renowned Ratnapura-Balangoda-Elahera triangle.
