0.69 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shape blue sapphire weighs 0.69 carat, and measures 6.56 by 4.84 by 2.33 millimeters, and originates from Ceylon Sri Lanka. The gem presents an intense color intensity coupled with transparent bodycolor, and it is reported as no enhancement, which confirms its natural untreated state. Clarity is described as very very slightly included evaluated at eye level, which in practical terms renders the stone effectively eye clean with only minute inclusions detectable under magnification. The combination of size, saturated Ceylon blue, and untreated provenance gives this sapphire a collectable profile, suitable as a center stone in a bespoke engagement ring or as the focal point of a refined gem collection, and The Natural Sapphire Company stands behind the gemological integrity and origin documentation for this piece.

The cutting style is a mixed brilliant cut executed on a cushion outline, a choice that deliberately balances broad face up presence with lively internal brilliance. Mixed brilliant in this context refers to the integration of brilliant style facets, optimized for light return, with tailored pavilion geometry to suit the elongated cushion proportions. The pavilion depth of 2.33 millimeters relative to the average diameter produces a depth ratio of approximately forty point nine percent, which is comparatively shallow, and this shallow pavilion enhances face up spread and maximizes perceived size for the stated carat weight. Facet junctions exhibit crisp lines and clean symmetry, and the excellent polish accentuates facet contrast and flash, producing strong scintillation under movement, and attractive dispersion in white light. The cushion outline moderates the light pattern into broad flashes on the crown and lively pinpoint scintillation from the pavilion, which together create a dynamic visual effect that reads as a bright, saturated blue across varied lighting conditions.

From a clarity and craftsmanship perspective the stone demonstrates high standards of lapidary finishing. The very very slightly included grade evaluated at eye level indicates that inclusions are minimal in both size and number, they do not interrupt the overall blue saturation, and they do not detract from the stone when set in typical jewelry orientations. The excellent polish and careful facet alignment reduce surface light leakage and emphasize the color zoning typical of Ceylon sapphires, allowing the intense color to present evenly across the table. The untreated origin from Ceylon further elevates the gem for discerning buyers who prioritize natural state and provenance, and it is particularly desirable because Sri Lankan sapphires are known for clarity and a lively, crystalline blue that responds well to mixed brilliant cutting. For practical considerations this sapphire benefits from settings that expose the pavilion to light, such as open prong or low bezel settings, which will maximize return of its internal brilliance while protecting the profile of the cushion shape. The Natural Sapphire Company can provide detailed gemological documentation, viewing images, and customization advice to ensure the stone performs as a centerpiece in any design, and our specialists are available to discuss setting options that preserve the untreated integrity while enhancing durability and optical performance.
