2.52 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shape blue sapphire weighs 2.52 carats and measures 7.99 by 7.71 by 4.68 millimeters, presenting proportions that translate to an approximate depth of 59.6 percent. The cutter executed a mixed brilliant scheme, pairing a brilliant style crown with a complementary pavilion arrangement designed to maximize return of light while simultaneously concentrating color saturation. Facet junctions are crisp, and the overall symmetry reads as well centered with consistent facet sizes across the pavilion and crown planes, which contributes to predictable light performance in both direct and diffused lighting conditions. Clarity is graded as very slightly included when evaluated at eye level, indicating that inclusions are minor, well confined, and do not interfere with the stones overall transparency or its ability to display high contrast scintillation. The polish is excellent, providing crisp facet reflections that enhance both the stones brilliance and its apparent saturation. Origin is Ceylon, Sri Lanka, a classic provenance known for producing sapphires with a vivid blue hue, and the stone has undergone heat treatment, a widely accepted and stable enhancement that optimizes color uniformity and reduces the visibility of minor inclusions without compromising structural integrity.

From a gem technical standpoint, this sapphire exemplifies an intentional balance between optical performance and material conservation. The cushion outline was selected to retain weight from the rough while enabling the cutter to deploy mixed brilliant faceting, which yields a lively interplay between small, scintillating facets on the crown and larger facets on the pavilion that act to pool and intensify the blue. The measured depth near sixty percent is engineered to support deep color without creating excessive windowing or extinction, a critical calibration for blue sapphires where hue saturation is paramount. Under magnification the inclusion suite and growth features are modest, consistent with a very slightly included grade, and the absence of surface-reaching fractures means the lapidary did not need to sacrifice symmetry for durability. The excellent polish indicates a final lap that removed minute surface disturbances, yielding high visibility through the stone and allowing the vivid color intensity to register cleanly to the naked eye. Heat treatment, properly disclosed, has been applied to stabilize and enhance the blue, refining tone and saturation and ensuring that the color will remain consistent with normal wear and standard jewelry maintenance procedures.

When considering long term value and heirloom potential, the material properties and cut characteristics of this sapphire are highly favorable. Sapphire is corundum, with a Mohs hardness of nine, second only to diamond in common jewelry materials, which provides exceptional resistance to abrasion and keeps facet edges sharp over generations. The cushion shape is a timeless silhouette that adapts well to a variety of mounting styles, enabling future owners to update settings while preserving the central gem. Because the cutter prioritized optical performance and structural soundness, the stone can be set in prong, bezel, or closed gallery settings with confidence, and edges on the cushion corners are well proportioned to accept secure protective mounting without excessive metal cover. The heat treatment applied is stable and irreversible under normal conditions, meaning the vivid color intensity that characterizes this stone will endure through routine cleaning and wear, contributing to the long term desirability that defines true heirloom gems.

At The Natural Sapphire Company we view provenance, craftsmanship, and material stability as the cornerstones of an heirloom. This sapphire comes from Ceylon Sri Lanka, a region with a well documented history of producing collectable blues, and it has been cut and polished to preserve both optical beauty and structural integrity. We recommend mounting options that respect the stones geometry and protect its pavilion and girdle, and we provide documentation of treatment and origin to accompany the gem so that future custodians will understand its history and value. With proper setting, routine professional cleaning, and mindful storage, this cushion sapphire will retain its vivid color, crisp facet structure, and visual presence for generations, becoming not only a piece of jewelry, but a tangible family legacy that can be reinterpreted by each successive owner.
