1.53 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This marquise shape blue sapphire weighs 1.53 carats and presents precise dimensions of 9.98 x 5.01 x 4.14 mm, a profile that balances length with an elegant waist width, producing a refined elongated silhouette on the finger. Cut as a mixed brilliant, the gem combines a finely faceted brilliant crown with a more architectural pavilion faceting scheme, producing both lively scintillation and strong light return. Transparency is excellent, the stone reads as transparent to the unaided eye, and the clarity grade is very slightly included evaluated at eye level, meaning that minor natural inclusions are present but are not detectable in normal viewing and do not interfere with the gem’s optical performance. The color presents with vivid intensity, a saturated and lively blue typical of high quality Ceylon material, and the polish is excellent, the facet junctions showing crisp execution and mirror like surfaces that maximize brilliance and color saturation. Enhancement analysis confirms no enhancement, the sapphire being presented in its natural state, and the documented origin is Ceylon Sri Lanka, a provenance long esteemed for fine blue corundum.

From a cutting and craftsmanship perspective the marquise exhibits meticulous attention to proportional geometry and facet alignment. The mixed brilliant strategy overlays a precise brilliant crown table and star facets with a pavilion arranged to enhance contrast and depth, producing flashes of bright white scintillation interspersed with saturated blue windows. The measured depth at 4.14 mm gives an overall depth proportion of approximately 55 percent relative to average diameter, a proportion that contributes to both strong light return and a pleasing face up spread. The faceting reveals consistent symmetry along the midline, and the pointed terminations are well formed, which is critical for the marquise profile where the integrity of the tips governs resilience and setting options. The excellent polish is evident on both crown and pavilion, minimizing light scatter and permitting the vivid blue body color to present cleanly, while the very slightly included clarity means the internal features are minor and do not interrupt the overall brilliance or the stone’s attractiveness when set.

Color analysis for this sapphire emphasizes a vivid blue with a medium to strong saturation and a tone that allows intense color without moving into dark or overly deep territory, resulting in a lively, vibrant presence in both daylight and artificial lighting. The hue is a pure to slightly bluish pure blue, with the typical luminosity associated with quality Ceylon sapphires that are prized for their clarity of hue and bright saturation. Because the gem is unenhanced, the color is wholly natural, and the combination of vivid intensity and the mixed brilliant faceting yields dynamic color modulation as the stone moves, ranging from deep royal blue flashes in the pavilion windows to brighter cornflower like highlights on the crown facets. This natural chromatic response is especially desirable to connoisseurs who value unaltered material and who appreciate the interplay of cut and color that a well executed mixed brilliant marquise can reveal.

As a gift the combination of shape, color intensity, natural origin and meticulous cutting makes this sapphire a striking and memorable choice for someone special, and The Natural Sapphire Company is proud to present it as an object that marries technical excellence with emotional resonance. The elongated marquise silhouette flatters slender and broader hands alike and lends itself to a range of settings from classic solitaire to elegant halo or bespoke three stone designs, and the pointed ends can be securely protected with well engineered prongs or a subtle bezel to ensure everyday wearability without compromising the profile. For buyers seeking a meaningful present the rarity of a 1.53 carat, eye clean, vivid Ceylon sapphire with no enhancement cannot be overstated, and the gem’s exceptional polish and thoughtful faceting will ensure visible brilliance the moment it is set.
