1.57 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire weighs 1.57 carats and measures 7.16 by 5.86 by 4.69 millimeters, presented in an elegant oval shape with a faceted, mixed brilliant cut. The mixed brilliant faceting combines precise step facets on the pavilion with brilliant facets on the crown, creating an optimized balance between depth of color and scintillation. The crown proportions and table size have been calibrated to maximize light return, so each facet junction contributes to controlled dispersion and lively pinpoint flashes. The cutting exhibits tight symmetry and even facet junctions, and the excellent polish enhances facet crispness, permitting high contrast between bright and dark areas that define classic brilliance.

Clarity is graded very very slightly included, evaluated at eye level, which in practical terms means the stone is effectively eye clean with inclusions that are minute and do not interrupt the light path. This near flawless internal clarity allows the intense yellow color intensity to transmit unimpeded through the gem, producing a consistent saturated hue from pavilion to table. The combination of intense color and very very slightly included clarity amplifies the apparent purity of tone, while the mixed brilliant architecture disperses light into controlled flashes that accentuate the gem when viewed from different angles. The excellent polish and precision cutting result in a smooth girdle and sharply defined facet edges, which together produce crisp reflections and a tactile finish that enhances perceived quality and longevity in jewelry settings.

This sapphire originates from Ceylon, Sri Lanka, and has been heat treated as a standard enhancement to stabilize and intensify its color, a common and accepted practice among skilled lapidaries. The gem displays the provenance characteristics associated with Ceylon material, namely bright, lively saturation and a warm, lemon to golden yellow character. From a design perspective, this 1.57 carat oval is ideal for a solitaire or halo mount, where the mixed brilliant faceting will deliver both sparkle and depth, or for a precision three stone setting that leverages its strong color. At The Natural Sapphire Company we document the measurements, cut grade, clarity, polish and treatment, and present this gem as a refined example of expert cutting and natural material. The stone’s near flawless internal clarity, intense color, and meticulous finishing ensure its beauty is enhanced from every angle, offering optical performance that rewards close inspection and daily wear alike.
