0.98 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent 0.98 carat, oval shape yellow sapphire measures 6.27 x 4.78 x 4.01 mm, and presents a carefully executed mixed brilliant cut that balances a brilliant crown with a modified pavilion faceting scheme to maximize both scintillation and depth of color. The combination of brilliant crown facets and elongated pavilion facets produces strong facet contrast and lively return of white and colored light, and with an evaluated clarity grade of very very slightly included at eye level the stone reads clean to the unaided eye, preserving excellent transparency and optical performance. The excellent polish allows crisp facet junctions and mirror like facet planes, and the gem is entirely natural with no enhancement, verified origin Ceylon Sri Lanka, a provenance that The Natural Sapphire Company documents and stands behind. The proportions result in an approximate depth of 72.6 percent relative to the mean diameter, and the cutter has optimized pavilion angles to compensate for the deeper profile, producing a compact face up appearance with concentrated color in the center and lively perimeter scintillation.

Under neutral daylight the sapphire displays its medium color intensity as a bright lemon to soft canary yellow with even saturation across the table, the mixed brilliant layout creating tight pinfire scintillation interspersed with broader flashes where the pavilion facets align, and the overall face up appearance is lively and evenly weighted. In direct sunlight the stone amplies contrast and shows more pronounced white flashes and strong scintillation, the crown facets acting as facets of return that break light into small, rapid flashes, while incandescent warm light shifts the hue slightly toward a richer golden yellow, increasing perceived saturation and warmth. Under cool white LED lighting the color reads a touch paler with faint lime undertones in some angles, but facet brilliance remains crisp and the excellent polish maintains high reflectance. In low ambient or candlelight the phenomenology becomes more discreet, the sapphire retaining transparency and showing a strong contrast between bright facet returns and deeper pavilion zones, which lends a sophisticated, gemological depth to the stone. This specimen is ideal for buyers who demand documented origin, uncompromised natural status, and a cutter s attention to facet geometry that optimizes both color and light performance, as offered by The Natural Sapphire Company.
