The cutting and finishing of this sapphire are executed with clear technical intent, the mixed brilliant cut employs a brilliant style pavilion paired with a modified step influenced crown which together maximize return from incident light while preserving the saturated blue body color, the facet architecture shows carefully proportioned pavilion facets which create a deep window free of obvious leakage, measured proportions yield a depth of five point four two mm relative to the average of length and width which calculates to approximately fifty one point nine percent depth, this depth percentage supports strong face up color without undue darkening from excessive depth, the polish is graded excellent, facet junctions are sharp and consistent which indicates precise lapidary work, the girdle is well controlled for secure setting, the symmetry of the cushion is tight and the table sits centered on the outline which facilitates predictable setability and consistent light performance.

Color and clarity define the character of this sapphire, the stone carries a dark color intensity that reads as deep royal to inky blue depending on light source, the saturation is strong which lends a velvety richness common to fine Ceylon sapphires that have been selectively heat treated to optimize chromium and iron chromophore distribution, clarity is described as very very slightly included when evaluated at eye level which reflects an eye clean presentation with only minor, finely dispersed internal characteristics visible under magnification, these minimal inclusions do not detract from the gem result, instead they confirm natural origin and contribute to the stone stability, the enhancement has been disclosed as heat treated which is an industry standard and controlled process that improves color and transparency while maintaining the integrity of the corundum lattice, origin is Ceylon Sri Lanka, a source renowned for sapphires that combine classic blue hues with a lively internal depth and textile like silk structure.

Practical considerations and provenance complete the technical profile, corundum offers a hardness of nine on the Mohs scale and a refractive index range of approximately one point seven six two to one point seven seven zero which ensures durability and lively optical performance, the dark tone of this piece pairs well with both white and yellow precious metals depending on design intent, settings that allow light to enter the pavilion will maximize scintillation given the mixed brilliant cutting style, this sapphire is suitable for high end engagement rings and bespoke jewellery where presence and long term wearability are priorities, The Natural Sapphire Company stands behind the description and provenance, we provide detailed imagery and can assist with setting recommendations that preserve the stone proportions while showcasing the five point six zero carat weight, for clients seeking a substantial, eye clean, technically well cut Ceylon sapphire this example represents premium quality grounded in measurable gemological attributes.
