2.57 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for a gemstone that answers both the heart and the standards of a discerning collector, this 2.57 carat transparent oval blue sapphire from Ceylon, Sri Lanka, presents itself as the solution you have been looking for. Designed to meet the needs of someone seeking an engagement gem that is both timeless and distinctive, or a collector who values natural character, this stone combines classic proportions with lively presence. The sapphire measures 9.00 by 6.81 by 4.85 millimeters, and its mixed brilliant cut has been executed to balance depth with surface brilliance, delivering scintillation that enliven a ring or a pendant. Graded as very slightly included when evaluated at eye level, the clarity allows for a clean face up appearance while preserving internal features that confirm natural origin. The color intensity is intense, a lively and saturated blue that evokes the classic Ceylon hue, and the polish is excellent, producing crisp facet edges and a mirror like finish. This sapphire has undergone heat treatment, a common and stable enhancement used to refine color and clarity, and each example from The Natural Sapphire Company comes with sourcing information and careful evaluation by our gem specialists.

What makes this sapphire unmistakable is its internal signature, the unique inclusions that provide character and proof of natural formation, rather than detracting from beauty. At face up view the stone reads as clean, but under loupe or microscope a subtle network of features reveals itself. Fine needle like rutile threads appear in limited areas, creating a soft silk effect that gently diffuses light and contributes to a velvety saturation of the blue. There are also minute reflective crystal pinpoints and tiny growth related pockets, which catch light and act like microscopic facets, adding liveliness without interrupting the overall transparency. You will notice delicate growth zoning lines that follow the hexagonal habit of corundum, a fingerprint of the crystal lattice that traces the gem back to the pegmatitic and metamorphic formations of Ceylon, Sri Lanka. In the pavilion there is a faint silky veil, visible only under magnification, which anchors the gem as a natural sapphire with a story of formation under heat and pressure, and which, after careful heat treatment, harmonizes with the intense blue to create depth and motion when the stone is viewed at different angles.

Beyond the visible charm these inclusions influence how the sapphire performs and how it will sit in a finished piece, which is essential for anyone planning an engagement ring or a bespoke collector setting. The mixed brilliant cut works in concert with the internal features to maximize both brilliance and color depth, the crown facets offering sparkle while the pavilion facets deepen the blue, and the minimal, well placed inclusions permit light to dance through the stone, rather than being scattered unevenly. The slight rutile silk softens the highlights, creating a rounded, glowing effect that is particularly flattering in day light, and the tiny crystal pinpoints act like stars within the stone when caught at the right angle, adding a private sparkle that is noticeable in intimate lighting. Because the stone is transparent and the polish is excellent, it will sit beautifully in a solitaire mount for an engagement ring, or in a halo setting if you wish to emphasize size and contrast, and because the integrity of the crystal is preserved with only very slight inclusions the sapphire maintains excellent durability for daily wear. The heat treatment has stabilized the color and clarity enhancements, providing peace of mind that the intense blue will remain consistent through normal wear and care.

Choosing this sapphire from The Natural Sapphire Company means selecting a gem that resolves the search for a rare and wearable jewel, one that harmonizes technical quality with natural personality. For the couple seeking an engagement ring that speaks of provenance and enduring beauty, this stone offers classic Ceylon color and eye pleasing clarity, and for the collector who appreciates natural inclusions as a map of geological history, the internal features are an unmistakable signature. Our gem specialists are available to provide further images, viewing options, and personalized advice about settings that will best showcase the stone, and we are happy to discuss custom mounting and design to ensure the final piece reflects your vision. Whether you are aiming for a simple, elegant profile that highlights the intense blue, or a more elaborate creation that plays with contrast and light, this 2.57 carat Ceylon sapphire will fulfill the desire for a jewel that is both beautiful and authentically natural, a treasure to be worn with confidence and passed down with pride.
