0.90 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.90 carat pear shape blue sapphire measures 5.96 x 5.74 x 3.41 mm, presenting an engineered mixed brilliant cut that balances weight retention with optimal light performance. The mixed brilliant faceting combines modified brilliant facets on the crown with precision oriented pavilion facets to maximize return and scintillation across the tear drop outline. The table proportions and facet junctions exhibit excellent symmetry and an excellent polish, producing crisp facet reflections and strong window control despite the gem size. The stone is transparent with an intense color intensity typical of Ceylon sapphires, showing saturated blue tones with lively internal contrast, clarity grade very slightly included, evaluated at eye level, which maintains overall transparency while adding natural character. Enhancement is heat treated, a stable and widely accepted practice that intensifies hue uniformity and removes silk without compromising structural integrity. Origin Ceylon, Sri Lanka, contributes to the gemology profile through its characteristic tone and saturation, and the specimen displays the optical performance expected from well cut corundum in this weight category.

For the collector seeking a generational heirloom, this sapphire embodies the technical and physical qualities that ensure longevity and provenance. Corundum hardness 9 on the Mohs scale confers exceptional resistance to wear and abrasion for daily wear in engagement settings, while the compact, well proportioned pavilion makes it highly suitable for secure V prong or bezel mounts that protect the vulnerable point of the pear shape. The mixed brilliant cutting preserves weight while producing stable light return that will not degrade with routine cleaning, and the excellent polish allows future re cutting or repolishing with minimal loss of weight if a descendant elects to modernize the design. Purchasing this stone through The Natural Sapphire Company ensures documented origin and traceability, enabling you to pair the gem with an independent gemmological report for long term provenance. With routine maintenance, periodic setting inspections, and conservative cleaning protocols, this Ceylon sapphire will retain its optical performance and market desirability, transitioning seamlessly from a bespoke contemporary setting into a cherished family heirloom for generations.
