1.68 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This superb oval blue sapphire offered by The Natural Sapphire Company is an exceptional addition to a high end gemstone collection, presenting a balance of size, color, and clarity that educated buyers seek. Weighing 1.68 carat, the gem measures 7.58 by 5.75 by 4.40 millimeters, and is cut in an elegant mixed brilliant style that combines the depth and color saturation of a step pavilion with the scintillation of a brilliant crown. The stone is transparent, and it displays vivid color intensity, a trait that immediately signals both visual impact and market desirability. The polish is excellent, producing clean facet junctions and strong light return, and the overall finish of the stone ensures that the color reads evenly across the table while maintaining lively sparkle. Origin is Ceylon Sri Lanka, a source long respected for producing blue sapphires with lively tone and saturation, and the stone has been heat treated, a stable and commonly accepted enhancement that enhances both color and clarity without diminishing the natural origin story that collectors prize.

Color is the primary determinant of value in blue sapphires, and this example demonstrates why provenance matters to discerning buyers. The vivid blue hue of this Ceylon sapphire combines a clear primary blue with balanced saturation, producing a hue that reads neither too dark nor too light, which is particularly important for wearable high end pieces and for stones destined for investment grade collections. Ceylon sapphires are frequently prized for their bright, lively blues, which differ from the deeper velvety tones associated with other origins, and collectors who value color purity and brilliance will appreciate how this gem presents color in both daylight and artificial light. The mixed brilliant cut is deliberately chosen to preserve color while maximizing scintillation, so the interplay of light across the crown facets produces flashes of brilliance that accentuate the vivid tone without washing out the color.

Clarity and treatment considerations are central to a well informed purchase, and this sapphire is described as very slightly included when evaluated at eye level, a clarity grade that indicates minimal inclusions that do not detract from the overall beauty when worn. These inclusions are consistent with natural origin and are often used by experienced gemologists to confirm authenticity and source. The stone has been heat treated, a widely accepted practice in the trade to improve color and clarity, and when performed correctly the treatment is permanent and stable under normal wear. For collectors interested in longevity and everyday wearability, natural corundum offers exceptional durability with a hardness on the Mohs scale of nine, and the excellent polish and proportioning of this oval ensure that it will set securely and continue to perform over time. For connoisseurs who assess gems with both scientific criteria and aesthetic judgement, the combination of vivid color intensity, minor included clarity, and professional cutting and finishing make this sapphire a compelling acquisition.

For those considering this stone for a bespoke engagement ring, a classic solitaire, or as part of a collection of investment grade gems, this sapphire offers flexibility and provenance that enhance long term value. The Natural Sapphire Company can assist with bespoke mounting suggestions that respect the stone geometry, such as lower profile settings to emphasize color depth, or halo styles to create contrast and apparent size, and we can provide additional high resolution imagery, light box viewing, and independent lab reports upon request to support appraisal and insurance. Collectors seeking a Ceylon sapphire with vivid color and excellent craftsmanship will find this 1.68 carat oval to be an exemplary choice, combining natural origin, trade standard enhancement, and the optical qualities that make sapphires prized by both connoisseurs and investors.
