4.40 Ct. Blue Sapphire from Burma (Myanmar)

This transparent cushion shape blue sapphire weighs 4.40 carat, measuring 13.72 by 8.82 by 3.89 mm, with a mixed brilliant cut that balances scintillation and color return. The clarity grade is very slightly included evaluated at eye level, allowing strong transparency and minimal impact on light performance, and the polish is excellent. Color is noted as vivid, presenting a deep, saturated blue that remains lively under varied lighting conditions. Origin is Burma, Myanmar, and the stone has no enhancement. The Natural Sapphire Company presents this gem with full provenance and cutting information for professional assessment and setting considerations.

When compared to classic Kashmir sapphires, which are often described as cornflower to velvety blue with a subtle violet undertone and a distinct silky diffusion of light, this Burmese example is more intensely saturated and carries a purer blue without the pronounced velvet effect. Versus Sri Lanka, historically known as Ceylon, which typically yields lighter, brighter, and more electric blues with higher tone variance, this gem sits at a deeper tone and retains vivid saturation rather than the airy brightness associated with Sri Lankan material. Compared to stones from Madagascar, which can range from light to deep blue and sometimes show a slightly greenish bias, this Burmese sapphire exhibits a more consistent pure blue hue. Thai and Cambodian sapphires frequently present darker, inky blues with gray or green modifiers, whereas this stone maintains clarity of hue and a clean, vivid blue. The mixed brilliant cut of this cushion concentrate color centrally while permitting lively facet reflections, making this specimen representative of the dense, richly colored Burmese sapphires prized for their balance of power and purity.
