5.52 Ct. Blue Sapphire Crystal from Ceylon (Sri Lanka)

This specimen is a semi translucented 5.52 carat various shape blue sapphire, measured at 16.03 x 7.52 x 6.66 mm, cut in a rough crystal style that preserves the original corundum habit and terminal faces. The rough crystal cut emphasizes the natural trigonal morphology of the sapphire, retaining elongated prism faces and softened terminations rather than imposing a conventional faceting scheme, resulting in an organic silhouette that reads as both raw and refined. The cutting approach was intentionally conservative to maximize carat weight and to preserve the original crystal lines, a strategy that enhances provenance and appeal to connoisseurs who prioritize natural form. The surface has been selectively polished to an excellent polish standard, producing clean, well defined facets where present and smooth natural faces where the cutter chose to leave the original crystal surface, providing optimal light return without altering the stone through aggressive re faceting.

Color and clarity are described with technical precision, the stone exhibits a very light color intensity within the blue spectrum, showing a paler, cool blue that responds to directional light with subtle shifts. As a semi translucent material, the sapphire transmits light in a diffuse manner, producing a soft internal glow rather than strong saturation or brilliance, a characteristic often associated with high quality Ceylon material at lighter color intensities. The clarity grade is very slightly included when evaluated at eye level, meaning that inclusions are present but not visually dominant, consisting of small pinpoint crystals and faint clouds that integrate into the stone without disrupting the overall aesthetic. These internal features are consistent with natural, untreated corundum from Ceylon, and they contribute to the gemological fingerprint that confirms no enhancement, no heating, no diffusion and no glass filling, preserving the stone in its natural state for accurate assessment and stable long term performance.

From a lapidary and design perspective this sapphire offers specific opportunities and constraints that should be considered by jewelers and collectors, the rough crystal cut and elongated profile make it especially suitable for bespoke settings that emphasize length and orientation such as custom bezels that follow the natural outline, or minimal claw settings that allow the stone to present its natural terminations. Because the color is very light and the material is semi translucent, setting choices that provide a neutral to dark backing will enhance perceived color intensity, while open backed designs will showcase translucency and internal character. The absence of enhancement and Ceylon origin together increase both the scientific interest and market desirability among buyers seeking natural, unaltered material, and The Natural Sapphire Company documents this origin and treatment status to provide transparency. The combination of 5.52 carat weight, 16.03 x 7.52 x 6.66 mm dimensions, rough crystal cutting style, very slightly included clarity at eye level, very light blue color intensity, excellent polish and no enhancement makes this sapphire a distinct specimen for collectors, artisans and designers who appreciate the technical nuances of natural corundum.
