4.14 Ct. Yellowish Orange Sapphire from Ceylon (Sri Lanka)

This yellowish orange sapphire began its story deep within Precambrian host rock, where over millions of years aluminous minerals recrystallized under sustained metamorphic heat and pressure to form crystalline corundum. Trace concentrations of iron and minor chromium were incorporated into the corundum lattice during growth, producing a warm yellow to orange hue that matured as the crystal cooled. Tectonic uplift and prolonged weathering liberated the sapphire from its primary matrix, allowing it to migrate into tertiary alluvial gravels characteristic of Ceylon Sri Lanka. Repeated episodes of burial and reheating at the crustal scale, combined with fluid interaction, refined the crystal habit and produced the clean, transparent material that cutters prize. This geological provenance imparts not only the intense color saturation but also the physical robustness and crystal symmetry that permit precise modern faceting.

Cut and finished to exacting standards by experienced lapidaries, this transparent cushion shape sapphire weighs 4.14 carats and measures 8.91 by 7.96 by 6.22 mm, presenting balanced proportions that optimize face up color while maintaining weight retention. The mixed brilliant cut integrates a brilliant facet arrangement on the crown with calibrated step or modified facets on the pavilion, delivering both scintillation and controlled color dispersion. The clarity reads very slightly included when evaluated at eye level, with minor natural inclusions that confirm natural origin without affecting durability, and the polish is excellent, producing crisp facet junctions and superior light return. Color is graded as intense with a yellowish orange hue that displays uniform saturation across the table under standard viewing conditions. The sapphire has been heat treated, a stable enhancement applied in controlled conditions to improve both color uniformity and apparent clarity, without the use of filling or diffusion processes. Sourced from Ceylon Sri Lanka and finished to presentational quality, this gem exemplifies the combination of geological pedigree and artisanal cutting practiced by The Natural Sapphire Company, and it is especially suited as a center stone in custom settings where color intensity and optical performance are principal criteria.
