2.68 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent oval blue sapphire from The Natural Sapphire Company is a refined example of Ceylon origin, weighing 2.68 carats, measuring 9.54 by 7.42 by 4.79 millimeters, with an elegant mixed brilliant cut and an excellent polish. The stone displays vivid color intensity, a saturated deep blue with lively tone that reads as vivid under both natural daylight and indoor lighting, and the mixed brilliant faceting was chosen to maximize both color saturation and internal light return. Clarity is graded as very slightly included when evaluated at eye level, meaning that the gem presents to the unaided eye as clean and luminous, with only minor pinpoint or feather inclusions visible under close magnification. The transparency and polish allow the table and pavilion facets to interact cleanly, producing a strong window of blue and lively scintillation across the surface. As corundum, sapphire offers a hardness of nine on the Mohs scale, and a high refractive index, characteristics that make this gem durable for everyday wear while maintaining an intense optical performance, and these physical properties underpin the long term value and usability of the stone.

The journey of this gem from mine to market reflects the careful stewardship that defines our sourcing and cutting philosophy at The Natural Sapphire Company. It began in the alluvial gravels and weathered rock outcrops of Sri Lanka, where local miners and regional buyers work in concert to recover gem rough that often shows exceptional color potential. From the mines the rough was examined for color zoning and inclusions, and selected pieces destined for fine faceting were forwarded to experienced cutters who assessed the rough for orientation that would best display the Ceylon blue. The mixed brilliant cut you see here was chosen specifically to enhance face up color and create a balanced pavilion depth for optimal light return. Prior to cutting the rough, controlled heat treatment was applied, a standard and widely accepted enhancement in the trade that reduces silk and alters trace element states to enhance hue and clarity permanently. After treatment the stone was carefully cut and finished, the facets precisely aligned and the girdle and pavilion executed to produce an excellent polish. The completed gem underwent gemological evaluation for clarity at eye level, measurement and weighing, and origin documentation consistent with the typical characteristics of Sri Lankan sapphires. Professional photography and secure handling brought the finished stone to market, where we present it with full disclosure of its treatment and origin.

For the educated buyer this sapphire represents a compelling synthesis of provenance, optical quality, and gemological transparency, and The Natural Sapphire Company stands behind both the particulars and the story. The vivid Ceylon blue color is a primary driver of value, particularly when combined with very slightly included clarity and a skilled mixed brilliant cut that enhances both sparkle and depth of color. The measurements of 9.54 by 7.42 by 4.79 millimeters make this an ideal size for a striking center stone in an engagement ring or a refined pendant, the oval outline producing an elongating effect on the finger while distributing weight efficiently for a pleasing face up spread. The excellent polish preserves crisp facet junctions and contributes to the gem appearing lively and glassy. Heat treatment is disclosed because it informs expected permanence and care, and it is important to note that this form of enhancement is stable and commonly accepted in trade, with the color improvements integrated into the stone at a structural level. For settings, a four or six prong mount in platinum or 18 karat white gold will emphasize the saturation and cool tone, while warm yellow gold will create a pleasing contrast that shifts perception of the blue toward a regal, deeper hue. Daily care is straightforward, warm soapy water and a soft brush are sufficient to maintain brilliance, and professional cleaning and inspection periodically will keep the setting secure. This gem carries both the geographical cachet of Sri Lanka and the technical merits that an informed collector or buyer seeks, and at The Natural Sapphire Company we provide clear documentation and guidance so that this 2.68 carat oval sapphire can be enjoyed with confidence for generations.
