1.60 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.60 carat oval yellow sapphire awaits discerning buyers, with dimensions of 7.60 x 5.73 x 4.28 mm, a mixed brilliant cut, a clarity grade of very slightly included at eye level, intense color intensity, and an excellent polish. This gem is from Ceylon Sri Lanka, and it has no enhancement, making it a naturally vivid example of yellow corundum. The mixed brilliant cut gives the stone a lively interplay of scintillation and broad flashes of light, with brilliant upper facets that return light energetically and a carefully faceted pavilion that preserves color saturation. Compared to typical commercial yellow sapphires that have been heavily heat treated or oiled to simulate uniform color, this Ceylon stone is rare in its untreated state, which means its reflective behavior is an authentic expression of its internal crystal structure, not an optical trick created by artificial alteration.

When discussing reflective qualities, the difference between this yellow sapphire and comparable yellow gemstones becomes clear. Corundum, the mineral species of sapphire, has a refractive index that produces stronger light return and more pronounced brilliance than quartz varieties such as citrine, and the mixed brilliant cut amplifies that advantage by concentrating bright flashes across the table and crown facets. Compared with yellow topaz, this sapphire maintains a longer lasting polish because corundum scores higher on the hardness scale, which preserves crisp facet junctions that are essential for sharp reflections over years of wear. Against yellow diamonds, sapphires show less dispersion or fire, yet the intense body color of this Ceylon piece turns light into warm golden reflections rather than the white sparkle that dominates diamonds, producing a richer, sunlit glow that reads as elegant and saturated in a ring or pendant. In direct comparison to other yellow sapphires on the market, particularly those with obvious clarity treatments or that exhibit cloudy milky areas, this gem stands out because its very slightly included clarity at eye level means inclusions do not mask the lively mirror like reflections and do not interrupt the stone’s ability to deliver crisp scintillation.

Beyond raw optical metrics, the overall reflective performance of this sapphire gives it practical advantages that translate into superior value. The excellent polish ensures that each facet surface acts like a high quality mirror, increasing contrast and enhancing the perception of depth, which many lower grade stones fail to achieve after only brief wear. The mixed brilliant cut is particularly effective in an oval outline, creating a broader face up appearance than many round stones of similar weight, and that wider table combined with intense color intensity results in a vivid, lively face up presence that catches attention while resisting the washed out look common in pale yellows. Because this gem is untreated, it will age predictably, and its natural color will remain stable under normal wear conditions, providing confidence that the reflection you admire today will be the reflection you admire for decades. At The Natural Sapphire Company we source and present stones like this Ceylon yellow sapphire with full disclosure, and when customers compare this offering to other market options they consistently note that the combination of untreated origin, precise mixed brilliant facet work, very slightly included clarity, and excellent polish yields reflective qualities that are measurably superior in everyday jewelry applications.
