0.88 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.88 carat cushion shape blue sapphire measures 6.51 x 5.00 x 2.97 mm, and has been faceted in a mixed brilliant cut that combines a faceted brilliant pavilion with a slightly stepped crown to optimize return of light while preserving color saturation. The mixed brilliant faceting creates a dense pattern of small star and kite facets on the pavilion beneath a well proportioned table, producing controlled scintillation and micro contrast without washing out the vivid blue hue. Clarity is graded as very very slightly included evaluated at eye level, which in practice yields eye clean appearance while retaining internal character that enhances sparkle through light scattering. Polish is excellent, the girdle is well finished and the symmetry is precise, all of which reduce light leakage and increase directed light return. Enhancement is heat treated, the standard and stable practice for blue sapphires, and the gem originates from Ceylon Sri Lanka, a source noted for producing lively, vivid blue material due to iron and titanium trace elements within the corundum matrix. The craftsmanship exhibited in the cutting and finishing emphasizes balanced pavilion depth and crown angle, achieving intentional tradeoffs between color depth and brilliance for maximum visual appeal in modest carat sizes.

When compared to more common gemstones the optical behavior of this Ceylon sapphire is distinct, and in many settings its perceived brilliance and presence can outperform stones of similar weight. Corundum has a refractive index approximately 1.76 to 1.77 and lower dispersion than diamond, so while it does not show the same fire as diamond it compensates with intense chromatic saturation and strong contrast scintillation created by the mixed brilliant faceting. Against blue topaz and aquamarine, which typically present paler tones and lower refractive indices, this vivid sapphire returns deeper, more concentrated blue light and exhibits greater visual weight per carat. Against other sapphires, the combination of Ceylon provenance vivid color intensity and the cutter s choice of mixed brilliant geometry yields a livelier scintillation pattern and more vivid face up color than step cut or shallowly cut stones. For collectors and connoisseurs this stone offers a technically refined balance of proportion, polish, and color, and The Natural Sapphire Company stands behind its origin and treatment disclosure, providing the documentation and setting advice to maximize the gem s optical performance in any bespoke jewelry design.
