The technical perfection of this sapphire complements its storied origin, its measurements lend themselves to a commanding presence in any bespoke setting. We present an oval shape that measures 10.06 x 8.30 x 5.60 mm, a mixed brilliant cut that marries depth and brilliance with classical proportions, and a clarity grade described as very very slightly included evaluated at eye level. Its vivid color intensity declares itself without compromise, a saturated yet luminous blue so evocative of deep oceans and midnight skies that it arrests attention from the first glance. The stone is transparent, allowing light to travel with minimal obstruction, and the excellent polish produces mirror like facet surfaces that scintillate with motion. The sapphire has been heat treated, a conventional and stable enhancement that refines color and clarity while preserving the natural origin and character of the gem. For the discerning buyer, the GIA certificate accompanying this stone affirms its identity, measurements, and natural origin, a critical assurance in a world where provenance matters as much as beauty.

Experience of this sapphire reveals how flawless quality intensifies beauty from every angle, transforming each viewing into a new discovery. Seen from above, the oval table offers an expansive window into the stone where the vivid royal blue floats with even saturation, revealing subtle secondary flashes and a velvety depth that seems to pull light inward. From the crown, the mixed brilliant faceting disperses highlights across the surface, creating a lively pattern that balances sparkle with a refined, satiny glow. The pavilion angles and facet junctions have been cut to exacting tolerances so that light returned to the eye is maximized, resulting in a lively flash that will animate in movement, while the overall transparency ensures that brilliance is not sacrificed for color. Viewed from the side, the pavilion depth and polished girdle reveal how expertly the cutter preserved weight while optimizing optical performance, a delicate negotiation that yields a gem which sits beautifully in a mount and displays consistent color whether seen under daylight, incandescent light, or evening illumination.
