1.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the riverbeds of Ceylon to the light of your jewelry box, this blue sapphire tells a story that begins in the heart of Sri Lanka, where ancient geological forces compressed corundum into crystalline form, and where generations of miners have expressed their respect for the land by carefully recovering precious stones from alluvial gravels and metamorphic veins. At The Natural Sapphire Company we partner with experienced local finders and cutters who honor that heritage, selecting rough material with promise and character. This particular stone emerged transparent and eager to be shaped, and our master cutter revealed its potential in an elegant oval, shaping it into a mixed brilliant cut that balances scintillation and color saturation. Weighing 1.40 carat, and measuring 7.47 by 6.11 by 3.61 millimeters, the gem was gently heat treated to deepen and stabilize its vivid blue, then given an excellent polish that leaves each facet smooth and reflective, ready to become the centerpiece of a cherished piece.

Up close the gem reads as vivid and alive, with a clarity described as very slightly included, evaluated at eye level, which means its small natural features do not distract from the gem’s overall transparency and depth, they only attest to its natural origin. The mixed brilliant cut, with its balance of crown and pavilion facets, was chosen to maximize both internal brilliance and face up color, so that the sapphire holds a rich, saturated blue when viewed in bright daylight, yet reveals deeper, velvety tones when seen in softer light. In midday sunlight the stone flashes with lively facets and a crisp, electric blue reflectance, while in overcast or shaded daylight it leans toward a pure, deep cornflower blue that feels calm and noble. Under warm incandescent or halogen lighting the sapphire warms subtly, reflecting sapphire blue with a touch of royal indigo at its heart, a result of the way the mixed cut allows color to pool and glow. In cool LED or fluorescent conditions the stone exhibits a brighter, slightly more electric blue, the facets scintillating with contrast. In candlelight or intimate evening lighting the sapphire closes into a sumptuous, velvety blue, the polish and cut catching pinpoints of light that dance with a quieter, romantic shimmer.

Wearing this sapphire is to carry a piece of Ceylonese landscape and craftsmanship with you, a gem that moves between moods as your day progresses. The vivid intensity of its color makes it equally arresting as a solitaire engagement gem or as the central stone in a halo or three stone setting, where the mixed brilliant cut will partner with delicate diamonds to amplify sparkle without stealing the sapphire’s character. Because of its excellent polish the gem will sit beautifully in a bezel or prong setting, and because it is corundum, with a hardness of nine on the Mohs scale, it is suited for everyday wear when set thoughtfully. The heat treatment applied is a respected and stable enhancement, performed to reveal the stone’s best color, and it is permanent under normal wear and care. At The Natural Sapphire Company we document origin and treatments carefully, and we are proud to present this Ceylon sapphire as a gemstone with both a known story and the optical qualities that make sapphires so beloved.

Imagine lifting the stone to your eye and watching the play of light as you move through a bright room, an evening garden, a candlelit dinner, an office lit with cool LEDs, and then back into the sun. Each environment teases a different facet of this gem, from crisp reflective flashes to deep, velvety pools of blue, and the journey from rough to jewel is audible in the way it holds its color and returns light. If you are seeking a sapphire that carries place and people in its history, that offers vivid color, a refined mixed brilliant cut, very slightly included clarity that confirms its natural origin, excellent polish, and secure heat treatment, then this 1.40 carat Ceylon oval from The Natural Sapphire Company invites you to make it part of your story.
