4.25 Ct. Green Sapphire from Ceylon (Sri Lanka)

The Natural Sapphire Company presents a timeless Ceylon green sapphire that speaks to the long lineage of gem cutters and collectors who have prized Sri Lankan stones for centuries. This transparent 4.25 carat cushion shape gem measures 10.33 by 8.12 by 5.15 mm and is fashioned in a mixed brilliant cut that balances table brilliance with step facet depth, creating a dignified and classical silhouette. Evaluated at eye level with a clarity grade of very very slightly included, the stone reveals only the faintest internal characteristics, allowing the medium intense green to read with consistent saturation. The polish is excellent and the gem is unenhanced, qualities that echo the old world preference for natural rarity and integrity. For those who value legacy, provenance, and honest beauty, this sapphire captures the reassuring continuity of Ceylon mining traditions while remaining perfectly suited to contemporary settings.

Compared to other gems in its category this green sapphire offers a distinctive interplay of light and color. The mixed brilliant cut amplifies internal fire and scintillation in a way that is more lively than the deeper pavilion oriented step cuts often used for emeralds, and because corundum has a higher refractive index than beryl, this sapphire returns light with crisper flashes and a more pronounced brilliance. Against green tourmaline the sapphire shows a firmer, gemmy reflection and greater resilience, while tourmaline often displays stronger dichroism and a softer, oilier luster. When set beside blue sapphires from Ceylon the green tone here presents comparable brilliance but a subtler pleochroic shift, allowing the cushion form to emphasize evenness of color rather than dramatic color change. The excellent polish and the lack of enhancement mean that light plays across the facets cleanly, rendering bright, jewel like highlights and deep, verdant interior glow. Durable and historically esteemed, this 4.25 carat Ceylon green sapphire from The Natural Sapphire Company is a heritage piece that will reflect centuries of tradition with every turn of the finger.
