3.23 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent 3.23 carat heart shape yellow sapphire measures 8.25 x 9.59 x 5.47 mm, and presents a balanced size and profile suitable for a variety of settings. The stone is faceted with a mixed brilliant cut, originating from Ceylon Sri Lanka, and has undergone heat treated enhancement to stabilize and enhance its medium color intensity. Clarity is graded as very very slightly included when evaluated at eye level, and the gem exhibits an excellent polish that contributes to its overall visual precision. The Natural Sapphire Company offers this gem as an example of disciplined cutting and careful treatment, with attributes recorded to aid considered selection.

The mixed brilliant cut and heart shape combine to optimize the sapphire to the material optical parameters, permitting controlled pathways for light to enter, reflect, and exit the stone. The pavilion is cut with angulation and facet proportions that promote internal reflection, increasing perceived brightness, while the crown facets and table plane are proportioned to permit efficient light return to the observer. The brilliant facets generate concentrated points of light and dynamic scintillation, whereas the modest step or modified facets in the mixed pattern afford larger, more even color windows, preserving the medium yellow tone without sacrificing brilliance. The heart outline requires careful symmetry, and in this stone the keel and lobes are aligned to maintain consistent facet relationships, reducing light leakage at the girdle and ensuring the faceted planes work in concert. Excellent polish on all facet surfaces minimizes light diffusion at the facet junctions, enhancing contrast and sharpening the return of white light and spectral flashes. The very very slightly included clarity grade indicates minimal internal features that do not interrupt the principal light paths at typical viewing distances, allowing the mixed brilliant schema to produce a lively balance of sparkle and color saturation. Heat treatment has been applied in a controlled manner to improve hue uniformity and to render the color more stable under normal wear. Together, these factors yield a heart shape yellow sapphire with measured dimensions and carat weight that present confident presence, refined optical performance, and reliable suitability for fine jewelry applications.
