15.09 Ct. Peach Sapphire from Ceylon (Sri Lanka)

This cushion shape peach sapphire weighs 15.09 carat, and measures 15.63 by 13.42 by 7.58 mm, presenting a substantial presence for a single stone, and offering excellent design flexibility for a statement ring or a pendant. The color is described as light in intensity, and the peach tone is subtle and refined, showing warm pink and soft orange undertones that become more apparent under warm light. The origin is Ceylon, Sri Lanka, a source historically prized for well colored and well formed sapphires, and this piece is offered by The Natural Sapphire Company as an untreated gem, with no enhancement recorded. The absence of treatment preserves the natural distribution of color and the crystal structure, a characteristic that discerning connoisseurs recognize as a marker of provenance and intrinsic value.

The cutting is a mixed brilliant style applied to a cushion outline, combining a brilliant facet arrangement on the crown with modified pavilion facets designed to maximize scintillation while maintaining the weight and outline of the original rough. The cutter achieved balanced facet geometry, producing crisp facet junctions and an excellent polish that allows light to enter and reflect cleanly from the interior planes. The proportions yield a depth of 7.58 mm against an average girdle dimension of approximately 14.53 mm, producing a depth ratio of approximately 52 percent, which is well suited to maintain good light return without excessive windowing or a heavy pavilion. The larger table typical of many cushion shapes presents the peach tone with clarity, while the mixed pavilion facets introduce a lively pattern of flashes when the stone is moved, enhancing its presence in jewelry without compromising the soft, rounded silhouette that defines the cushion form.

Clarity is graded as included at eye level, which indicates the presence of internal features visible without magnification, and these inclusions are consistent with natural sapphires from Sri Lanka, contributing to the unique character of the stone rather than detracting from its appeal. The included nature may include pinpoint crystals and internal growth structures that interact with light to create localized effects and depth, and in hand the stone presents an appealing internal landscape that specialists and collectors appreciate for its fingerprint of origin. Sapphire hardness of nine on the Mohs scale ensures excellent durability for everyday wear, and the cushion shape with moderately low girdle profile enhances resistance to impact. Because this is an untreated stone, the integrity of the crystal chemistry is intact, and when set with appropriate protective considerations, it will retain its appearance and value over time.

For use as a striking gift for someone special, the combination of substantial carat weight, rare untreated Ceylon origin, and refined peach coloration positions this sapphire as a memorable focal point for milestone pieces, including engagement and anniversary jewelry. Design recommendations include warm colored alloys such as rose gold to intensify the peach nuances, or a yellow gold mount to provide a classic, radiant backdrop, while a white metal mounting will create a modern contrast that emphasizes the gem s lighter tones. A four or six prong setting will allow maximum light exposure and display of scintillation, whereas a low bezel can offer increased protection for active wearers. For a bespoke piece commissioned through The Natural Sapphire Company, the cutter s excellent polish and well balanced facet schema will polish up beautifully within custom settings, and our workshop can advise on optimal pavilion exposure and bezel thickness to minimize stress and preserve the stone s long term beauty. In presentation this sizeable cushion peach sapphire delivers a rare combination of technical refinement and emotive warmth, making it an exceptional and striking gift for someone truly special.
