36.99 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This translucent blue sapphire weighs 36.99 carats and measures 32.40 x 9.50 x 14.55 mm, presenting an elongated various shape that preserves the original crystal morphology. The rough crystal cut emphasizes natural growth faces and stepped planes rather than conventional symmetrical faceting, which creates an organic interplay of polished and planar surfaces. Color grading indicates an intense blue saturation, consistent with premium Ceylon origin, and the overall translucency allows internal color zoning to read uniformly when set in light. Clarity is graded very slightly included, evaluated at eye level, with minor internal features that remain discreet against the stone full body color. The polish is excellent, applied selectively to accentuate the stone natural planes and to enhance surface luster and light return, while the lack of enhancement confirms the material is completely natural from mine to market.

The combination of substantial carat weight, striking dimensions, and high clarity makes this sapphire ideal for a bold statement piece. At nearly thirty seven carats, the gem commands scale and presence, its elongated profile well suited to center ring designs that span multiple fingers or to bespoke pendant mounts that preserve the crystal silhouette. The intense color intensity and excellent polish maximize visual impact, and the very slightly included clarity ensures that the interior does not distract from surface color, providing an expansive field of blue when viewed face up. For mounting, consider an open back or bezel setting oriented along the long axis to exploit translucency and to allow light to traverse the crystal planes, or a minimal prong array to showcase the raw geometry while protecting delicate termination points. As corundum, this sapphire benefits from a high refractive index and strong vitreous luster, which coupled with the selective polishing produces a lively surface sheen and discreet internal glow. Sourced from Ceylon Sri Lanka, and presented by The Natural Sapphire Company, this unheated, untreated specimen offers both collector value and design versatility, making it a singular choice for a bespoke, museum caliber statement jewel.
