4.31 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This C.Dunaigre certified Blue 4.31 carat emerald cut blue sapphire from Ceylon is a study in enduring elegance, offered exclusively by The Natural Sapphire Company. Measured at 9.69 x 7.60 x 5.89 mm, this transparent gem carries a clarity grade of very very slightly included when evaluated at eye level, a vivid color intensity, and an excellent polish. Heat treated to reveal its purest hue, it resonates with the storied legacy of Sri Lankan sapphires that have graced royal collections for centuries. The emerald cut is a classic choice that speaks to tradition, with long step facets and restrained geometry that recall the refined sensibilities of the art deco era, and this stone exemplifies how craftsmanship and provenance combine to make a piece feel timeless.

In comparison to other sapphires, and to the broader family of blue gemstones, the reflective character of this emerald cut is distinct and compelling. Unlike brilliant cuts that rely on countless small facets to create scintillation, the emerald cut produces broad flashes of light and a hall of mirrors effect that emphasizes depth of color and clarity. Against cushion and oval sapphires, which tend to sparkle with lively pinfire reflections, this emerald cut offers a more controlled and majestic presence, allowing each wave of blue to read as a pure, uninterrupted field of color. Compared to sapphires from other classic sources, the Ceylon origin contributes a clarity and brightness that makes reflections appear crisp and vivid, while Kashmir sapphires are often prized for their velvety diffusion and Burmese stones for their saturated power. The polish and facet precision of this gem ensure that light is returned with clarity rather than noise, so the viewer experiences broad luminous planes rather than frenetic sparkle. For those who honor lineage and prefer a statement that is both historical and refined, this sapphire harmonizes the ancient allure of Ceylon blue with the clean, architectural beauty of the emerald cut, a combination that endures across generations.
