2.31 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This exceptional transparent Other certified yellow sapphire weighs 2.31 carats, and presents a classic cushion shape with refined proportions, dimensions of 8.91 by 7.11 by 4.29 mm. The stone originates from Ceylon Sri Lanka, a locality renowned for producing sapphires with lively tone and fine clarity, and it is offered by The Natural Sapphire Company with full disclosure that no enhancement has been applied. The cutter has selected a mixed brilliant cut which combines the scintillation of a modern brilliant facet arrangement with the softer outline of a cushion profile, resulting in a gem that balances lively sparkle with elegant shape. The clarity grade is eye clean when evaluated at eye level, which means that there are no inclusions visible to the unaided eye that would interrupt either the visual pleasure or the structural integrity of the stone. The color presents as medium intense yellow, evenly distributed through the crystal, and the finish is described as excellent polish, a detail that enhances the apparent color depth and allows the stone to interact optimally with light.

From a gemological perspective, the mixed brilliant faceting geometry of this stone is engineered to allow maximum light play, a quality that trained buyers will immediately appreciate. The mixed brilliant style places a concentrated sequence of triangular and kite shaped facets on the crown above a refined table, and a complementary orientation of pavilion facets below, all calibrated to direct light back to the viewer. In yellow sapphires this arrangement emphasizes both brightness and the subtle spectral flashes that come from the dispersion of corundum. The refractive characteristics of corundum, with a refractive index around 1.76 to 1.77, mean that facet angles matter greatly, and the cutter has used proportions that favor strong return of white light while preserving color saturation. Because the stone is eye clean, light paths are largely unobstructed, so sparkle and windowing are minimal, and the pavilion geometry supports active scintillation even when the gem is set in jewelry. The cushion outline softens the optical presentation, giving a larger apparent face up size relative to other cuts of similar weight, while the mixed brilliant pavilion creates flashes of internal light that animate the stone with movement.

For the discerning buyer who values provenance, craftsmanship, and natural condition, this Ceylon yellow sapphire represents an attractive combination of attributes that justify collector interest and long term value. Untreated sapphires from Sri Lanka carry a premium due to their natural color and the historical reputation of the region, and the lack of enhancement here preserves both investment quality and a clean gemological profile for future resale or appraisal. The excellent polish increases wearability, and the durable cushion shape with these proportions adapts well to a variety of settings including four prong solitaire, halo ring, or bezel set pendants where the pavilion geometry can be positioned to optimize light return. At 2.31 carats and with dimensions that are well suited for a statement ring, this stone will sit prominently on the finger while maintaining classical balance.
