Sri Lanka, the “Island of Gems,” is home to some of the most exquisite sapphires in the world, with Rambuka village being one of the most coveted sources of high-quality blue sapphires. At City of Gem, we take immense pride in sourcing and crafting these natural treasures, ensuring that every gemstone reaches the hands of collectors, jewelers, and enthusiasts in its most refined form. Today, we share the journey of a remarkable 2.70 Ct rough blue sapphire, sourced directly from Rambuka and transformed into a mesmerizing 1.20 Ct cushion-cut masterpiece.
Sourcing the Rough Stone – A Direct Link to Rambuka’s Mines
Rambuka is renowned for its intense-colored blue sapphires, often regarded as some of the best in Sri Lanka. Our team, based near these rich mining grounds, works closely with local miners to obtain the finest gems, ensuring that each sapphire is directly sourced without unnecessary intermediaries.
This particular rough sapphire, weighing 2.70 Ct with dimensions of 8.8 x 5.7 x 5.2 mm, was handpicked from the heart of Rambuka’s mining region. Its deep blue hue and exceptional quality made it an exciting find, but the cutting process was not without its challenges. To secure this raw beauty, we offered miners a fair price, ensuring ethical sourcing while keeping the gem’s authenticity intact.
The Cutting Process – Transforming Rough into Perfection
Every gemstone has a story, and cutting is where its true potential is revealed. This particular stone was entrusted to Mr. Janaka, City of Gem’s skilled cutter, whose expertise brought out its full brilliance. The cutting process was challenging due to oxide bands and surface inclusions, which needed careful assessment and precision handling.
Through meticulous cutting, we were able to remove inclusions and create a stunning 1.20 Ct cushion-shaped sapphire, measuring 6.4 x 5 x 3.9 mm. The transformation was incredible—the rough’s deep blue tones evolved into a refined cornflower blue, an ideal hue sought after in the gem trade.
Why Rambuka Blue Sapphires Are So Special
Rambuka’s sapphire deposits are celebrated for producing highly saturated, vivid blue sapphires, often compared to the finest Ceylon sapphires. Unlike commercial-grade stones that pass through multiple hands before reaching the market, our sapphires come directly from the miners to City of Gem. This ensures authenticity, ethical sourcing, and a unique connection between the gem and its new owner.
Here are a few reasons why Rambuka blue sapphires stand out:
Exceptional Color Intensity – Rich, vivid blues that captivate collectors and jewelers worldwide.
Natural & Unheated – These sapphires retain their original beauty, untouched by artificial treatments. High Clarity & Transparency – Our stones undergo careful selection, ensuring the finest clarity.
Ethically Sourced – By purchasing directly from miners, we support local communities while maintaining fair trade practices.
