1.59 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

This transparent greenish blue cushion sapphire weighs 1.59 carat, with precise dimensions of 6.77 x 5.45 x 4.48 mm, and originates from Ceylon Sri Lanka. The gem displays an intense color intensity and an excellent polish that emphasizes surface luster and facet delineation. Clarity is graded as slightly included when evaluated at eye level, with natural internal characteristics that are typical for material of this origin and size. This sapphire has been heat treated as an enhancement, a standard and stable process used to optimize color and clarity in natural sapphires. The Natural Sapphire Company provides this stone as a calibrated, ready to set gem, suitable for a range of fine jewelry applications.

The cushion outline is complemented by a mixed brilliant cut that combines a geometrically arranged brilliant facet pattern on the crown with a carefully modified pavilion. The crown facets are configured to fragment and refract incoming light, while the pavilion geometry is oriented to channel light back through the table, resulting in controlled return and scintillation across the face of the stone. This geometric faceting allows maximum light play, producing balanced flashes and a subtle interplay between green and blue tones as the viewing angle changes. The proportions maintain depth for color saturation while preserving table size for visual presence, and the excellent polish ensures crisp facet junctions and minimal surface diffusion. For designers and gem setters, this sapphire offers predictable optical behavior in bezel, prong, or tension settings, and it responds well to both warm and cool metal tones depending on the desired contrast with the greenish blue hue. The combination of origin, cut, and finish makes this sapphire a technically refined choice for projects that require controlled light performance and natural character.
