1.76 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This exceptional 1.76 carat color change sapphire is a scarce and extraordinary offering, presented exclusively by The Natural Sapphire Company. Transparent and alive with shifting hues, this oval shaped gem measures 7.39 x 6.70 x 4.59 mm, and possesses an auction house quality presence that will immediately reveal itself to anyone who understands true rarity. Sourced from the legendary soils of Ceylon Sri Lanka, this sapphire carries both provenance and personality, a combination that elevates it beyond a mere jewel into the realm of the collectible and the bespoke. Owning this stone places you among a very small circle of connoisseurs who appreciate the authentic interplay of origin, craftsmanship, and natural beauty.

Beyond its notable origin and weight, the gem’s cutting and finish define its character in precise ways. The stone has been fashioned into an elegant oval shape and finished with a mixed brilliant cut that blends classic proportions with modern geometry, a technique chosen to maximize both fire and brilliance. The clarity grade is slightly included when evaluated at eye level, which is to be expected in natural sapphires and which in this case only enhances its individuality and depth. The polish is excellent, allowing mirror like surfaces to form on each facet and to capture light without obstruction. The sapphire has undergone professional heat treatment, an enhancement that improves stability and accentuates the vivid color intensity that this gem displays.

What makes this sapphire truly exceptional is the way its geometric faceting has been executed to optimize the stone’s optical performance. The mixed brilliant cut on this oval translates into a carefully arranged sequence of crown facets and pavilion facets, placed with precision to direct maximum light back through the table and crown. The crown facets act as windows and mirrors simultaneously, catching rays from above and reflecting internal flashes back toward the observer. The pavilion facets have been angled to facilitate internal reflection and to produce a scintillation pattern that is both lively and refined. Each facet engages in a choreography of light, creating a kaleidoscope of flashes that change as the stone moves, and that intensify the color change phenomenon so prized by collectors. The geometry of the cut balances large luminous facets with smaller scintillation facets, allowing broad flashes of color to wash the stone as well as pinpoints of light that animate the surface.

The changing personality of this sapphire under different lighting is an experience to be savored, and it is amplified by the precise faceting and superb polish. In cooler fluorescent light the gem can read as a deep, vivid bluish violet, a tone that appears almost regal. Under incandescent light the stone shifts, warming into stronger violet and even purple tendencies, revealing secondary notes that are subdued in daylight but become prominent in evening settings. This subtle but definitive color change is the sapphire’s signature, and it is made more legible by the gem cutter’s decision to employ a mixed brilliant pavilion and crown, which accentuate both saturation and sparkle. The slightly included clarity allows tiny internal structures to scatter light in delicate ways, adding character without detracting from the gem’s transparency. The overall impression is one of complexity, as the stone seems to hold within it its own private weather, responding to the light with dignity and drama.

Because gems of this pedigree are uncommon, this sapphire is offered as a singular treasure, a piece that can be set as a centerpiece in a bespoke ring, a pendant, or an heirloom brooch. When set by a master jeweler, the geometric faceting will work in tandem with the metal framework to create an object that commands attention while remaining refined. At The Natural Sapphire Company we appreciate that collectors and clients desire both assurance and discretion, and we will work with you to maintain the gem’s integrity while recommending settings that protect the pavilion and showcase the oval silhouette. This is not a mass produced item, but rather a rare natural phenomenon that has been thoughtfully enhanced and expertly finished to become wearable art. For those who wish to own something genuinely unique, this 1.76 carat Ceylon color change sapphire represents an opportunity to claim a jewel that will be treasured for generations.
