This transparent 1.32 carat oval blue sapphire combines precise proportions with a saturated color and strong clarity, making it an exemplary piece for a discerning collector. The stone measures 7.60 x 5.92 x 3.65 millimeters, yielding a length to width ratio of approximately 1.28 to 1, a proportion that favors classic oval symmetry while retaining a bold face up presence. The material has been assessed as eye clean at standard viewing distances, indicating that the internal characteristics are not visible to the unaided eye, and the gem presents an unencumbered visual field that enhances light return. Origin is Ceylon Sri Lanka, a source with a well documented history for producing sapphires with lively blue tones. Enhancement through controlled heat treatment has been disclosed, a stable, widely accepted process that optimizes hue and clarity without degrading long term durability, and the surface finish is graded as excellent polish, ensuring crisp facet junctions and minimal surface blemishes under magnification.
The cutting geometry is a mixed brilliant scheme, integrating a faceted crown with a more angular pavilion structure to balance scintillation and overall brilliance. The crown exhibits a proportionate table relative to the girdle, allowing broad light entry, while the pavilion facets are configured to redirect light back through the crown in a controlled manner, producing strong internal flash and a lively pattern across the face. Given the millimeter profile and a measured depth of 3.65 millimeters, the relative depth percentage is about 54 percent when calculated against the mean of length and width, a depth that supports both color saturation and optimum brilliance. Facet symmetry is precise, facet edges meet cleanly, and the girdle appears even and finely finished, contributing to predictable mounting behavior and minimizing the risk of chipping during setting. The mixed brilliant design is particularly effective in this oval outline, as it preserves the vivid body color while introducing multiple planes of reflected light for dynamic visual interest.
Color evaluation of this Ceylon sapphire is characterized by vivid intensity, with a primary blue hue that reads as saturated and pure in daylight and incandescent lighting. The stone demonstrates consistent color distribution across the table and shoulders, with only subtle zonation that does not detract from the overall uniformity. The saturation level is high without being opaque, allowing internal light transmission that produces both depth of color and lively brilliance. Observers will note the classic Ceylon tendency toward a bright, slightly vivid blue rather than a heavy inky tone, making this gem particularly versatile for display within a high end collection or for prominent use in bespoke jewelry. Minimal pleochroic behavior is present as expected for corundum, but the cut orientation has been optimized to present the most desirable blue face up, a decision that enhances perceived saturation and mitigates any directional color shift when worn.
For collectors seeking a refined addition that balances aesthetic appeal with sound gemological parameters, this sapphire is an outstanding candidate. The combination of a well controlled heat treatment, eye clean clarity, vivid color intensity, and an excellent polish delivers both immediate visual impact and long term value stability. From a mounting perspective, the robust girdle and even pavilion make the stone suitable for a range of high end settings, including bezel secure mounts that protect the girdle, or classic prong styles that maximize light return. Conservatively cut dimensions and a stable treatment history simplify future appraisals and resale considerations. The Natural Sapphire Company stands behind transparent documentation and provenance information, and we recommend formal certification if required for insurance or investment records. Proper setting and occasional professional cleaning will preserve the excellent polish and light performance, making this Ceylon oval sapphire a technically accomplished and visually compelling centerpiece for any elevated gemstone collection.
