2.58 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire weighs 2.58 carats, and presents in a classic heart shape with dimensions of 7.63 x 9.07 x 4.98 mm. The proportions yield an overall depth of 4.98 mm relative to an average diameter of 8.35 mm, producing a depth percent of approximately 59.7 percent, a proportion that sits well within the preferred range for mixed brilliant heart cuts and supports balanced light return. The faceting is a mixed brilliant style, with a brilliant fashioned crown and a modified pavilion geometry, executed to emphasize both scintillation and face up brilliance. The heart outline is well defined, with symmetrical lobes and a crisp cleft, and the faceting plan preserves a broad table that enhances the gemware appearance when mounted, while still allowing for lively dispersion and contrast patterning under direct light.

Clarity is graded as very very slightly included when evaluated at eye level, an indicator of exceptional transparency for natural sapphires. In practical terms the stone is effectively eye clean, with any internal features confined to minute crystalline signatures or isolated pinpoint inclusions that require magnification to be resolved, and these do not interfere with the passage of light or the pattern of reflections. The polish is excellent, demonstrating precise facet junctions and smooth facet planes that reduce light leakage and contribute to crisp facet contrast. The mixed brilliant faceting combines small star and kite facets on the crown with carefully oriented pavilion mains, producing controlled scintillation and return of white and colored flashes. The girdle is consistent for the proportions, and there is no evidence of surface reaching or significant windowing, which further supports stable optical performance in a variety of mounting orientations.

Color is described as a medium intensity yellow, presenting a lively lemon to soft canary tone that is both saturated enough to read distinctly as yellow and restrained enough to retain high levels of clarity and light return. The yellow color in corundum is commonly associated with iron impurities in the crystal lattice, and in this example the trace element chemistry produces a clean hue that is versatile for a range of design palettes. Origin plays a material role in the character and market appreciation of this gem, as it is sourced from Ceylon, Sri Lanka, a locale renowned for producing sapphires with bright, transparent color and fine crystallographic development. Ceylon provenance carries a recognized premium among connoisseurs and collectors, owing to a long documented history of gem quality material and a reputation for producing stones with a characteristic balance of tone and clarity that is difficult to replicate elsewhere.

The absence of enhancement in this sapphire is a key value attribute, it is presented in its natural state with no heat treatment or diffusion, and no clarity filling, which supports both longevity and desirability for collectors and bespoke jewelry projects. From a setting and design perspective the heart shape and the measured proportions lend themselves to a variety of applications, including solitaire ring settings where the cleft faces the finger, pendant designs that center the lobes, and bespoke three prong or five prong mounts that secure the pointed tip while allowing the crown facets to interact freely with incident light. For protection of the point, a subtle bezel or prong cup can be used without compromising visual access to the pavilion reflections. Given the excellent polish and eye clean clarity, the stone will perform strongly under both daylight and artificial lighting, displaying balanced brilliance and scintillation. The Natural Sapphire Company offers this gem alongside full documentation of its physical attributes, and our team is available to provide additional imaging, viewing under controlled illumination, and bespoke mounting recommendations to preserve the gem provenance and optical integrity when set.
