1.78 Ct. Blue Sapphire from Ceylon (Sri Lanka)

There are few moments in a life of discerning taste that call for a gem so singular and so refined, this 1.78 carat cushion shape blue sapphire is one such moment, offered exclusively through The Natural Sapphire Company. Sourced from Ceylon, Sri Lanka, this stone carries the storied legacy of one of the world’s finest sapphire locations, translated into a vivid blue that immediately commands attention. The sapphire measures 7.09 by 6.02 by 4.99 millimeters, and its mixed brilliant cut has been executed to marry scintillation with a classic cushion silhouette. At an eye level clarity grade of very very slightly included, the stone reads exceptionally clean and transparent, while an excellent polish allows light to play across every facet with a satin smooth finish. The stone has been heat treated, a traditional enhancement applied to many fine sapphires to optimize color and clarity, and in this example the treatment has revealed an intense, lively blue that is both deep and luminous.

Weight is often the single most persuasive factor in determining a sapphire’s presence and rarity, and at 1.78 carats this cushion sapphire occupies a rare position between everyday sizes and truly exceptional weights. Many sapphires of vivid hue and high clarity are found in fractions of a carat, and even among larger stones those that combine color saturation, transparency, and a pleasing cushion dimension are scarce. The 1.78 carat weight gives this gem physical gravity and visual authority on the hand, producing a face up size that is noticeable without overwhelming, a balance prized by collectors and connoisseurs. The proportions of 7.09 by 6.02 millimeters together with a depth of 4.99 millimeters show that the weight is distributed to preserve both brilliance and color intensity, rather than being sacrificed to bulk. In gem valuation the interplay between carat weight and optical performance is crucial, and here the weight elevates the value not simply as a number but as a measure of rarity, desirability, and potential as a centerpiece for bespoke jewelry.

Owning this sapphire is an invitation to join a select circle who appreciate the subtle but profound distinction between a fine stone and the exceptional. The mixed brilliant cut produces a lively interplay of flashes and a velvet like depth to the blue, while the excellent polish ensures every light return is graceful and precise. Because of its refined clarity and vivid color intensity, this sapphire will sit spectacularly in a variety of settings, from a minimal solitaire that honors the gem itself to a bespoke ring that layers contrast and metalwork for dramatic effect. At The Natural Sapphire Company we curate such gems for clients who seek rarity and provenance together, and we are prepared to assist with bespoke mounting options that honor the stone’s weight and character.
