2.03 Ct. Peach Sapphire from Ceylon (Sri Lanka)

This specimen is a transparent 2.03 carat peach sapphire cut in an emerald cut shape, with dimensions 8.51 x 6.01 x 4.09 mm, and an excellent polish. The color displays a very light peach intensity, distributed evenly across the pavilion and crown to the extent typical for corundum of this hue from Sri Lanka. Clarity is described as very slightly included when evaluated at eye level, which in an emerald cut presents as small, discreet internal features confined to a few facets rather than pervasive cloudiness. The cutting style emphasizes symmetry and facet alignment, resulting in broad, geometric light returns that favor clarity and color presentation over scintillation. The sapphire has been heat treated, a standard and permanent enhancement that refines color and clarity without altering the gem’s fundamental durability or wear characteristics. The documented origin is Ceylon Sri Lanka, an origin historically associated with both delicate color and good transparency in lighter tone sapphires.

In terms of reflective behavior this sapphire exhibits the vitreous luster inherent to corundum, combined with the step cut geometry of the emerald style, producing broad, mirror like flashes of light rather than a spray of small glittering highlights. Corundum has a refractive index in the range 1.762 to 1.770 and a low dispersion value near 0.018, which together yield a restrained but clean white brilliance and minimal fire. Compared side by side with brilliant cut sapphires, which maximize scintillation and localized sparkle due to numerous small facets, an emerald cut sapphire like this delivers a more elegant and architectural light performance that highlights internal clarity and the stone’s subtle peach tone. When compared with other gemstones that are often considered in the same design category, the differences are noticeable and instructive. Spinel, with a refractive index around 1.712 to 1.717, has a slightly lower refractive effect and a similar vitreous luster, so a spinel will tend to return light a bit more softly than this sapphire. Morganite and certain lighter topaz varieties present lower refractive indices and therefore less intense light return, but they may show more dispersion under some lighting conditions depending on cut. Diamond, by contrast, exhibits both a higher refractive index and significantly greater dispersion, so its fire and sparkle are in a different optical class altogether than corundum. Within the sapphire family itself, stronger colored sapphires and those with deeper tones can appear to reflect light more richly as a function of color saturation, whereas this very light peach sapphire emphasizes clarity and broad reflective planes rather than saturated depth.

Practical observation in jewelry settings follows from these optical properties. In a bezel or four prong setting the emerald cut planes will reflect surrounding light sources in broad flashes providing a calm and refined visual presence. In open gallery settings the stone’s step cut will act almost as a window through which the peach tone reads consistently, making it suitable for designs where color subtlety and a measured, architectural look are desired. The natural origin from Sri Lanka and the heat treatment together account for the stone’s even color distribution and enhanced transparency, while the very slightly included clarity status suggests that careful facet planning was used to position and minimize the visibility of any internal features. The Natural Sapphire Company presents this sapphire as an example of how cut, origin, and polish interact to produce a gem whose reflective qualities are defined more by broad luminous planes than by sparkling scintillation, making it a distinct choice for those who prefer a restrained, elegant light performance in corundum.
