15.10 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

Long before it arrived in our display at The Natural Sapphire Company, this yellow sapphire began its life deep within the ancient earth of Ceylon, Sri Lanka. Over countless years geological forces forced mineral rich fluids into cavities where corundum crystals slowly formed, capturing light and time in their crystalline lattice. Local miners who know the hills and streams like the back of their hand uncovered the rough, and the stone spoke of warmth and sunlight even before it was touched by the hands of a cutter. This is a natural gem with no enhancement, a stone that carries the honest story of its origin, and it arrives to you with a GIA certificate that confirms its natural origin, its identity as sapphire, and the careful grading that accompanies fine gems.

At the heart of this narrative is the gem itself, a transparent yellow sapphire weighing 15.10 carats, fashioned into an elegant oval shape with dimensions of 14.97 x 13.34 x 8.48 millimeters, and cut in a mixed brilliant style that blends the sparkle of a brilliant arrangement with the depth of step cutting. The GIA grading notes a clarity of eye clean, evaluated at eye level, which means that the stone offers an uncluttered window into its warm golden core, free from significant inclusions that would distract from its beauty. The color intensity is medium intense, a balanced and radiant yellow that catches the light without overwhelming, and the polish is excellent, so each facet meets the next with precision and reflective harmony. Together these characteristics allow the pavilion and crown facets to play with light in a lively symphony, producing scintillation and a lively glow that reads as sunshine in motion.

The journey from rough to this refined oval was guided by the careful decisions of cutters who understand how to honor a stone while maximizing its beauty and durability. At The Natural Sapphire Company we choose rough that promises both character and structural integrity, then assign cutting to artisans who respect the gem pattern and work to retain weight while opening brilliance. The mixed brilliant cut was chosen to enhance the stone’s fire and to distribute yellow color evenly across the table, while the proportions were adjusted so the gem sits comfortably in a variety of settings. The excellent polish magnifies the eye clean clarity and allows light to travel through the gem unfettered. Because this sapphire is natural and untreated, it retains the full story of its formation, and because it is GIA certified, you receive both beauty and documented assurance of the gem’s attributes.

Beyond its beauty, this yellow sapphire is built for the rhythms of daily life. Sapphires are corundum, a mineral that registers a nine on the Mohs hardness scale, second only to diamond, and that inherent hardness gives them exceptional resistance to scratches from everyday contact. When set securely by an experienced jeweler, the stone resists chipping and abrasion, making it an ideal choice for rings and other jewelry you will wear often. The mixed brilliant cut and excellent polish also help hide minor surface wear that can accumulate over long use, and because the gem has no heat or other enhancements, its color remains stable and true over time. For care, warm soapy water and a gentle brush will restore its sparkle, and routine checks of the setting will ensure the stone remains secure. At The Natural Sapphire Company we stand behind the gem with documentation and service, and we are available to advise on settings that protect the girdle and crown while showcasing this remarkable 15.10 carat Ceylon yellow sapphire as the everyday heirloom it was born to become.
