5.04 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 5.04 carats, and it is presented in an asscher octagon shape with precise dimensions of 9.48 x 9.33 x 5.41 mm. The cutting style is faceted, and the gem displays the hallmarks of a classic asscher cut with stepped facets and balanced symmetry. Clarity is graded as very very slightly included as evaluated at eye level, and the stone benefits from an excellent polish that enhances surface finish and light return. Color intensity is vivid, offering a rich saturated blue that remains lively under varied lighting. The sapphire is heat treated, a standard enhancement that improves color and clarity, and its documented origin is Ceylon, Sri Lanka. These technical attributes combine to create a gemstone that is both visually compelling and rigorously described for informed appraisal and design planning.

Optically, the asscher cut imparts a strong architectural character, creating a central table that allows the vivid blue to read with depth and consistency, while the stepped faceting around the pavilion provides controlled reflections and a structured play of light. The faceted pavilion and crown work together to balance color saturation with internal brightness, so the stone appears vivid without losing detail to dark zones. The excellent polish ensures that facet junctions are crisp, and that the eye level clarity presents as clean to a viewer observing the gem mounted in jewelry. Proportionally, the near square outline at roughly nine and a half millimeters across offers a presence that is substantial yet wearable, and the slight elongation along one axis provides an elegant profile that complements both slender and broader settings.

In practical terms, this sapphire is well suited to both casual and formal settings, pairing equally well with minimalist everyday designs and with more elaborate ensembles for evening wear. Its durability as corundum makes it appropriate for rings intended for frequent wear, while the asscher octagon shape lends itself to classic solitaire, halo, three stone, or bespoke creations with geometric restraint. On the hand the stone presents as a decisive focal point without overwhelming proportions, and when set it provides a refined silhouette for modern engagement rings or for signature cocktail pieces. For care, routine cleaning with mild warm soapy water and a soft brush is recommended, and professional inspection of the mounting will ensure long term security. The Natural Sapphire Company provides this sapphire with full disclosure of origin and enhancement, and offers support for custom setting and consultation to optimize metal choice and setting style according to the gem dimensions and design intent.
