1.51 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This GIA certified Blue sapphire presents as a transparent oval weighing 1.51 carat, with dimensions of 7.51 x 5.94 x 4.15 mm. The stone is fashioned in a mixed brilliant cut, with a clarity grade of very very slightly included when evaluated at eye level. Color is catalogued as intense, and the polish is graded excellent. There has been no enhancement performed on this sapphire, and its origin is Ceylon, Sri Lanka. The Natural Sapphire Company offers this gem with full documentation, confirming its natural origin and the GIA assessment.

The mixed brilliant cut is executed with geometric precision to promote maximum light play, combining a faceted crown that disperses incoming light with a pavilion geometry that returns light through the table for optimal brilliance. The arrangement and proportions of the crown facets, girdle, and pavilion facets create contrasting zones of reflection and scintillation, producing lively flashes and a stable, saturated face up color. At the listed proportions the pavilion depth and table relationships maintain strong light return, avoiding windowing or excessive darkening, while the excellent polish enhances facet junction clarity and precise facet planes. Because the sapphire is transparent and free of significant diffusion, the geometric faceting reveals internal color zoning and subtle inclusions only at magnification, rather than at the eye, contributing to a clean visual presentation in everyday wear. This sapphire adapts well to both classic prong mounts and low profile settings, offering a balanced presence on the finger without overpowering the design, and the oval outline yields a flattering optical size relative to its weight. The combination of GIA certification, natural Ceylon origin, intense color, and meticulous mixed brilliant faceting ensures a gem that performs exceptionally under varied lighting, delivering measured brilliance and depth, as represented by The Natural Sapphire Company.
