1.69 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.69 carat cushion shape blue sapphire from Ceylon Sri Lanka is offered by The Natural Sapphire Company, transparent in body and presenting a vivid color intensity that is both deep and lively. The gem measures 6.42 by 6.39 by 4.65 millimeters, and carries a mixed brilliant cut with an excellent polish, no enhancement, and a clarity grade of very slightly included evaluated at eye level. The cushion outline with softly rounded corners and gently curved sides produces a pleasing balance between face up area and depth, allowing the sapphire to sit with presence in a variety of settings while maintaining a refined profile suitable for fine jewellery.

The mixed brilliant cut employed on this sapphire is designed to enhance the stone inherent properties of light reflection, by combining a brilliant style crown with a modified pavilion geometry that controls internal light return and contrast. The crown facets disperse incoming light into bright flashes and delicate spectral hints, while the pavilion facets act to redirect and concentrate that light back through the crown, creating sustained brilliance and dynamic scintillation as the stone moves. The cutter has balanced facet sizes to reduce large windowing and to promote even color distribution, which in this specimen works together with the vivid color intensity to produce saturated blue tones without dark or washed out areas. The excellent polish preserves crisp facet junctions and smooth facet planes, ensuring minimal surface scattering and optimal mirror like reflection. Given the very slightly included clarity at eye level, the internal inclusions do not interrupt the principal light paths, allowing the mixed brilliant architecture to perform efficiently and to emphasize both face up brightness and depth of hue. This sapphire therefore offers a technically considered combination of proportions, cut style, and polish, yielding a gemstone that presents consistent brilliance, well defined scintillation, and a lively display of rich Ceylon blue.
