0.77 Ct. Blue Sapphire from Ceylon (Sri Lanka)

At The Natural Sapphire Company we present a rare opportunity to own a gem that marries classic form with exceptional provenance, a transparent round blue sapphire weighing 0.77 carat, precisely measured at 5.98 by 5.98 by 2.66 mm. This stone is cut in a mixed brilliant style to maximize fire and scintillation, and it displays an intense color intensity with an excellent polish. The clarity grade is very very slightly included, evaluated at eye level, which means the inclusions are nearly imperceptible to the naked eye and serve only to confirm the natural origin of the crystal. Origin is Ceylon, Sri Lanka, a source celebrated for producing some of the most desirable and historically significant blue sapphires in the world. We present this sapphire not as a mass produced commodity, but as an exclusive piece for collectors and connoisseurs who understand that rarity is measured in precise details, and that each fractional carat increases both the allure and long term value of a gemstone.

The weight of 0.77 carat is central to the stone's character and its investment profile, and understanding the significance of that weight explains why this sapphire is especially coveted. In the marketplace, the shift from half carat to three quarters carat and beyond is where demand intensifies, and where a stone begins to stand out as a centerpiece rather than an accent. At 0.77 carat this sapphire sits in that sweet zone, substantial enough to command attention and to anchor a bespoke engagement ring or a bespoke pendant, while remaining exclusive because such high quality, well proportioned stones in this specific weight range are uncommon. The apparent size is further amplified by the mixed brilliant cut, which is specifically engineered to make the most of the millimeter spread and depth, creating an optical presence that feels larger than raw carat weight alone might suggest. For discerning buyers who seek scarcity as much as beauty, the 0.77 carat weight is a precise statement, an intentional choice that elevates the piece above mass market offerings and situates it within a small group of gemstones that are immediately recognizable as desirable and collectible.

Color and clarity work in tandem here to increase both visual impact and market value, and this Ceylon, Sri Lanka origin sapphire demonstrates both with conviction. The intense blue color is the sort of hue that collectors prize, vivid enough to be unmistakable, yet with the complexity and depth that invites prolonged viewing. Ceylon sapphires are known for their lively, velvety tones and for a color that changes subtly under different lighting conditions, and this stone carries that pedigree. The clarity grade of very very slightly included, with inclusions assessed at eye level, provides assurance that the sapphire is naturally formed and unmasked by synthetic processes, while the excellent polish ensures that light dances across the crown and facets with unfettered brilliance. The mixed brilliant cut enhances both the color saturation and the dispersion of light, so that the 0.77 carat weight reads as a luminous, living color field rather than a static block. For connoisseurs who appreciate the provenance story as much as the visual spectacle, the Ceylon origin is a mark of historical and geological significance that adds measurable cachet to the piece.

Because rarity is amplified by condition and provenance, additional attributes of this sapphire further distinguish it as an elite offering from The Natural Sapphire Company. The stone has been heat treated, a widely accepted and disclosed enhancement that refines color and stability, bringing out the best expression of natural color without compromising integrity when fully and honestly disclosed. The excellent polish and the meticulous mixed brilliant cutting reflect the human artistry applied after the rough is sourced from Ceylon, Sri Lanka, and that combination of natural quality and masterful cutting is precisely what buyers of rare gems seek. Owning this 0.77 carat round sapphire is to belong to a select group who appreciate that individual stones of superior cut, color, and clarity do not appear often in the market. We offer detailed documentation and a clear provenance trail, and we stand ready to collaborate on bespoke settings that will showcase the gem as a singular heirloom. For those who desire exclusivity, this sapphire is not merely an acquisition, it is an invitation to possess something exceptional, a defined expression of rarity and refinement available now through The Natural Sapphire Company.
