1.14 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This transparent 1.14 carat cushion shaped bi color sapphire measures 6.35 x 6.29 x 3.67 mm, and presents a balanced profile that speaks to careful rough selection and expert cutting. The mixed brilliant cut combines a modified brilliant crown with a precision faceted pavilion, producing a complex contrast pattern that enhances both large scale brilliance and fine scintillation. The stone displays intense color intensity with a distinct bi color split between deep velvety Ceylon blue and a warm golden zone, and it is unenhanced and natural from Ceylon Sri Lanka. Clarity is graded very very slightly included evaluated at eye level, and the excellent polish and meticulous symmetry ensure that facet junctions remain crisp, allowing unobstructed light passage and minimal light leakage. The Natural Sapphire Company presents this gem as an example of how superior material and disciplined lapidary technique are combined to retain both weight and optical performance.

Structurally the sapphire benefits from corundum s inherent optical properties, with a refractive index around one point seven six that promotes strong internal reflection, and a modest dispersion that yields controlled fire without overpowering the primary blue hue. The pavilion depth of three point sixty seven millimeters on an average table span of approximately six point three two millimeters yields a depth proportion of approximately fifty eight percent, an empirical sweet spot for mixed cuts where pavilion facets act as efficient light channels returning rays through the crown. The mixed brilliant arrangement aligns star and kite facets on the crown with elongated pavilion facets to produce multiple planes of return, creating an animated play of light as the stone moves. Precision faceting and an excellent polish maximize edge contrast and dynamic scintillation, and the very very slightly included clarity at eye level ensures that internal features are sufficiently minor so as not to interrupt the light architecture.

For a discerning buyer who values technical excellence, this sapphire demonstrates how material origin, absence of enhancement, and exacting cutting choices collectively produce a sparkle that is both lively and nuanced. The interaction of facet geometry, crown height, and pavilion proportions in this cushion form creates exceptional light return, making the visual impact of the bi color transition all the more striking. The Natural Sapphire Company offers this gem to collectors and connoisseurs who appreciate the science of light and the craft of cutting in equal measure.
