1.31 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the moment this sapphire left the earth, its story has been one of light, patience, and careful hands. Born in the ancient gem gravels of Ceylon, Sri Lanka, this transparent blue sapphire weighs 1.31 carats, and measures 6.69 by 5.72 by 4.30 millimeters. The oval shape and mixed brilliant cut allow a lively interplay of facets, while a medium intense blue color gives it depth without heaviness, and an excellent polish reveals a glass like surface that captures and returns light with clarity. Evaluated at eye level the stone carries a clarity grade of very very slightly included, a honest and natural signature that speaks to genuine material rather than synthetic perfection. Heat treated to enhance its color in a way that respects the gem, this sapphire arrives to the bench as a finished jewel waiting for its setting, and every millimeter of its form carries the imprint of the earth that made it.

The path from mine to market matters, and we take that responsibility seriously. The Natural Sapphire Company builds relations with trusted suppliers in Sri Lanka, partners who work with small scale miners and local communities, and who adhere to transparent and ethical practices. This sapphire comes to us with a clear origin story from Ceylon, and that traceability allows us to share more than a photograph, it allows us to share a provenance. Ethical sourcing means fair wages and safer working conditions for miners, investments in community projects that protect livelihoods, and attention to environmental stewardship as stones are recovered from riverbeds and gravel terraces that have hosted sapphires for millennia. When you choose this gem, you are choosing a piece with a chain of custody that we are proud to stand behind, a jewel that is part of a living landscape rather than a story of exploitation.

Once the rough left the mine, master cutters and experienced lapidaries took up the next chapter of the journey. The mixed brilliant cut was selected to maximize both color and sparkle for this particular oval, a shape that balances the lively fire of a brilliant style with the elegant silhouette of an oval outline. At 6.69 by 5.72 by 4.30 millimeters the proportions are thoughtful, offering mounting flexibility for everything from a delicate solitaire to an intricate halo setting. Our gemologists at The Natural Sapphire Company evaluated the stone under controlled lighting and at eye level, noting the very very slight inclusions that confirm its natural origin while the excellent polish indicates the final hands that brought its surface to mirror like smoothness. Heat treatment, a common and accepted enhancement for sapphires, was applied to stabilize and enhance the blue hue, and this process is fully disclosed as part of our commitment to honest descriptions.

For the conscious consumer, this sapphire fits into a collection that values both beauty and responsibility. Its medium intense blue is versatile, pairing gracefully with white metals for a modern look, and warming beside yellow gold for a timeless expression. At 1.31 carats it reads as a meaningful center stone for an engagement ring, a refined accent in a cocktail ring, or a treasured component in an heirloom piece designed to be worn daily and passed down. Choosing a gem with documented origin and ethical sourcing practices means you are investing not only in aesthetics, but in principles, and that alignment brings a different kind of satisfaction when you wear it. Durability and everyday wearability are intrinsic to sapphire, a gem that resists scratches and holds polish, and with proper care, this stone can remain a vivid and personal emblem for many years.
