2.53 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

This 2.53 carat cushion shape blue sapphire measures 8.17 by 6.28 by 4.67 mm, and is presented by The Natural Sapphire Company with full attention to lapidary detail. The piece is translucent, exhibiting a vivid color intensity that reads as a deep, saturated blue under standard daylight and daylight corrected lighting. The overall form is a classic cushion outline, but the cutting style is a traditional sugar loaf, producing a pronounced central crown that rises to a small, nearly trigonal apex. The sugar loaf configuration alters the way light interacts with the body color, producing broad zones of saturated blue rather than a scattering of tiny facet returns, and the excellent polish applied to the surfaces maximizes surface luster while maintaining a soft, velvety internal glow.

The sugar loaf cut on this sapphire is executed with precision, balancing a raised, pyramidal crown with gently rounded girdle-to-crown transitions, and a shallow pavilion that enhances color depth by limiting light leakage. The lapidary approach emphasizes mass and color rather than brilliancy, so the faceting plan is simplified and controlled, with larger planes and a single primary apex facet that functions as a quasi table. This technique requires careful preforming during the rough reduction stage to avoid windowing or color zoning, and the cutter must orient the crystal lattice to preserve pleochroic effects. The excellent polish reported ensures that surface reflections remain crisp, and that the tactile finish is mirror like, which is particularly important for sugar loaf stones where surface quality directly affects perceived color saturation.

Clarity is graded as included at eye level, and the stone shows natural internal features that are visible to an unaided eye, consistent with its classification. These inclusions manifest as subtle internal texture and localized veil like zones, which interact with the sugar loaf geometry to produce a soft diffusion of light across the dome. For many collectors and connoisseurs this type of translucency enhances the stone, imparting a velvety, almost luminous character to the blue, and the internal features serve as natural fingerprint of origin and treatment history. The vivid color intensity is notable, with a strong, clean blue hue and minimal brown or green modifiers, characteristics frequently associated with fine Sri Lankan sapphires. The piece is heat treated, a standard and widely accepted enhancement for corundum, and the treatment is applied to optimize both color and clarity while preserving the inherent crystal structure and natural inclusions that contribute to the stone's personality.

From a setting and care perspective, the sugar loaf cushion benefits from a protective mounting that secures the girdle and guards the rounded pavilion and apex from impact. Bezel settings, partial bezels, or well designed prong assemblies that cradle the silhouette work well, and these options also allow the crown to remain visually prominent so that the sugar loaf form can present its full thermal and optical character. Because the stone carries an included clarity grade, routine cleaning with warm soapy water and a soft brush is recommended, while aggressive ultrasonic or steam cleaning should be considered only after an expert inspection if internal fissures are evident. The Natural Sapphire Company can advise on custom mounting choices that respect the gemology and aesthetic of this sapphire, and we can supply detailed documentation of weight, dimensions, origin, enhancement, and cut characteristics for client assurance. This sapphire represents a confluence of traditional Sri Lankan material, considered lapidary execution, and a visual language defined by saturated color, measured translucency, and a highly polished sugar loaf profile.
