1.41 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

Out of the warm, weathered soils of Ceylon comes a story that begins long before it reaches your hand, a tale of heat, time, and the slow patience of the earth. Deep within Sri Lanka the forces that create corundum gathered over millions of years, concentrating aluminum and oxygen into the hard, enduring crystal that becomes the sapphire. Local miners, some working traditional methods passed down through generations in places like Ratnapura, followed the veins and river sands where these treasures reveal themselves after the mountains erode. From that ancient and storied landscape the rough stone that would become this particular gem was selected with an eye for clarity and potential color. At The Natural Sapphire Company we follow that journey closely, honoring the people and places that produce these gems, and ensuring that each sapphire we present carries with it the provenance and respect it deserves.

This round yellow sapphire weighs 1.41 carat, with precise dimensions of 6.57 x 6.58 x 4.33 mm, and a mixed brilliant cut that marries pavilion depth and crown dynamics for a lively personality. Its appearance is transparent with a light color intensity that reads as a soft, sunny yellow, and its clarity is graded as very very slightly included when evaluated at eye level. The polish on this stone is excellent, which means the facets are finished to a mirror like smoothness so that every plane interacts with light without disruption. Importantly, this sapphire is unheated, no enhancement, which makes it a rarer and purer expression of its origin. The fact that it is of Ceylon origin influences the character of its hue and its overall charm, because Sri Lankan yellow sapphires are often admired for their delicate yet luminous tones that sit beautifully on the finger or in a pendant.

What makes this sapphire sparkle in a way that feels unmatched is a combination of its natural crystal structure, its cut, and the absence of treatments that would otherwise alter how light behaves within it. Corundum is aluminum oxide, Al2O3, a mineral with a dense and orderly lattice that gives the gem a high refractive index, approximately 1.76 to 1.77, which means light bends strongly as it enters the stone. That bending is the first ingredient for brilliance. The mixed brilliant cut then sculpts that light by using a carefully calculated arrangement of facets on both the crown and the pavilion. The crown facets break incoming light into bright flashes that the eye perceives as sparkle, while the pavilion facets act as mirrors that return that light back through the table when the angles are precise. With very very slight inclusions only visible under close inspection, there is minimal internal disruption to the path of light, so contrast and scintillation remain lively across the face of the gem. Excellent polish seals the performance, eliminating microscopic surface irregularities that could scatter light and dull the effect. The result is a gem that flashes with clear, clean brightness, with nuanced flashes of warmth from its yellow tone.

When you choose this unheated Ceylon yellow sapphire from The Natural Sapphire Company you are not only choosing a beautiful stone, you are choosing a story that began in ancient geology and passed through many hands of craftsmanship. In the studio a cutter translated the rough geometry into a mixed brilliant round, balancing weight retention with optical performance to preserve the stone at 1.41 carat while maximizing its fire and brilliance. Set simply to show off its natural light, or placed in a bespoke design to become a personal heirloom, this sapphire adapts gracefully to every style. Its size sits comfortably as a striking solitaire or as a glowing center in a more elaborate setting, and its durable hardness promises enjoyment for generations. We invite you to imagine how this Ceylon gem will catch the light as you move, to feel the connection to place and craft embedded in its structure, and to contact us for further details on setting options or provenance documentation.
