1.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional 1.13 carat oval blue sapphire from Ceylon is presented by The Natural Sapphire Company as a technical specimen for connoisseurs and gem cutters who appreciate refined proportion and optical performance. The stone measures 6.59 by 5.66 by 3.67 millimeters, a compact profile that balances spread and depth to deliver optimal face up presence for its weight class. The oval outline has been carefully maintained to preserve symmetry along both principal axes, producing even light dispersion across the table, crown, and pavilion. Weight distribution is engineered to minimize windowing while maximizing apparent diameter, making this sapphire an ideal centerpiece for a bezel set antique style mount or a classic four claw ring where the crown is free to meet incident light without obstruction.

The mixed brilliant cut has been executed to emphasize brilliancy at the table and scintillation across the crown facets. The cutter combined a brilliant facet arrangement on the crown with a graduated faceting schema on the pavilion to control light return and to deliver lively contrast patterning. Facet junctions show tight symmetry, and the facet planing follows consistent angles so that the pavilion facets act as effective light guides, returning spectral flashes rather than allowing light to escape through the base. The result is a compact, lively scintillation with small, finely defined light and dark areas that animate with movement. The oval proportions and the chosen pavilion geometry reduce extinction near the girdle and maintain a continuous play of light across the table, which is particularly valuable for sapphires with lighter color intensity where cut engineering must compensate to enhance perceived saturation and sparkle.

Color and clarity are presented with precision, the sapphire exhibits a light color intensity within the blue range, with subtle violet leaning in certain viewing orientations due to pleochroic behavior inherent to corundum. Facet alignment and the mixed cutting approach moderate the pleochroic shifts so that the stone reads uniformly attractive when set, yet reveals its complex optical character when rotated under directional illumination. Clarity is graded as very very slightly included evaluated at eye level, these inclusions are minute and do not affect transparency or optical performance under practical inspection, they are typically confined to internal needlelets or pinpoint crystals that can add to the gemological fingerprint without compromising brilliancy. The jewel is transparent and lively, and since there is no enhancement recorded, the crystal lattice is in its natural state, which increases its desirability for collectors who prioritize untreated provenance. The Ceylon origin contributes expected characteristics such as a refined, delicate blue and an overall light tonal range that is emblematic of Sri Lankan material.

Craftsmanship extends beyond faceting into polish and finish, the stone carries an excellent polish which produces crisp facet junctions, sharp flashes and a clean surface that eliminates drag lines or polish haze. The girdle has been finished to a uniform thickness to facilitate secure setting while preserving optical performance, and the pavilion culet has been controlled in size to avoid windowing. For setting recommendations, an elevated four claw or a low bezel with open gallery will maximize light entry to the crown and allow the pavilion to reflect with maximum return, while a halo setting in white metal can visually deepen the perceived color without altering the natural character of the sapphire. This sapphire responds well to directional lighting, and for photography or in person viewing, a north south orientation tends to show the most balanced blue to violet transition. The Natural Sapphire Company presents this 1.13 carat oval Ceylon sapphire as a technically refined gem, suitable as a solitary collector piece or as the focal point in high quality bespoke jewellery, its untreated status, precise mixed brilliant cutting, excellent polish, and measured proportions ensure it will occupy a prominent position in any collection, especially for buyers who value documented origin and artisanal cutting provenance.
