0.74 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent, 0.74 carat round blue sapphire presents precise dimensions of 5.25 by 5.26 by 3.47 millimeters, with a depth percentage of approximately 66.0 percent calculated from its measured proportions. Cut as a faceted gemstone in a mixed brilliant configuration, the stone combines a brilliant crown faceting pattern with a modified pavilion arrangement, a design choice that balances optimal light return with deep color saturation. The mixed brilliant cut yields crisp facet junctions and generous internal reflection, while an excellent polish enhances the surface luster and the clarity of light transmission. Clarity is graded as slightly included when evaluated at eye level, these minute internal characteristics being localized and not detracting from overall transparency, and often contributing to a subtle depth and character when viewed in direct light. The color displays vivid intensity, a saturated cornflower to royal blue typical of high quality Ceylon material, and the sapphire has undergone routine heat treatment to stabilize and enhance its color uniformity and transparency, consistent with trade practice for Sri Lankan sapphires. Origin is Ceylon, Sri Lanka, a source long esteemed for blue sapphires that combine vibrant hue with lively optical performance.

From a lapidary and setting perspective, this gem exemplifies meticulous workmanship intended to maximize both brilliance and color. The mixed brilliant faceting, when executed with precise symmetry and well proportioned girdle dimensions, preserves strong scintillation under motion while allowing the body color to remain dominant under even lighting. The nearly equal measurements on the girdle plane indicate a true round outline that translates into even bezel or prong settings, and the 66.0 percent depth favors color retention over excessive brightness loss, making this sapphire particularly suitable for classic solitaire rings or as a central accent in multi stone designs where color depth is paramount. Excellent polish at facet junctions reduces light leakage and contributes to the perception of larger apparent size, while the slight inclusions seen at eye level are often masked by carefully chosen mounting choices and by the stone geometry. For designers who prioritize refined optical behavior, the mixed brilliant scheme here offers an effective compromise between fire, scintillation, and color saturation, and the measurements provided make it straightforward to calculate expected dimensions in bezel cups or collet settings.

Beyond technical merits, this sapphire carries a narrative that complements its physical attributes, a romantic provenance that weaves together place, hue, and the subtle inclusions that make each stone unique. Imagine a monsoon dusk along the southern coast of Ceylon, when the ocean takes on an indigo glow and the first stars prickle through a humid sky, that intense blue captured and concentrated within a single polished round. The vivid color intensity evokes those nights, and the slight inclusions read as miniature constellations, a private cartography visible only to the lover who studies the stone closely. Heat treatment can be seen as a parallel to the refining fires of personal commitment, an intentional enhancement that reveals deeper radiance without altering the sapphire core. At The Natural Sapphire Company we pair such technical understanding with an appreciation for story, and this 0.74 carat Ceylon sapphire becomes more than a measured object, it becomes a romantic talisman. For a connoisseur who values exacting cut, documented origin, and the poetry of a stone that reflects both geography and personal memory, this sapphire offers an exceptional blend of gemological integrity and emotive resonance.
