1.18 Ct. Orangish Yellow Sapphire from Ceylon (Sri Lanka)

This gem is a transparent orangish yellow sapphire weighing 1.18 carat, cut in a classic emerald cut shape with crisp step facets, truncated corners, and a broad table that concentrates color, measured at 6.93 by 5.06 by 3.26 millimeters. The pavilion shows well aligned step facets that terminate in a neatly faceted culet plane, and the girdle is even for secure setting with minimal excess. Proportions result in a depth of approximately fifty four percent relative to the average of the length and width, a dimension that balances face up spread with depth saturation for this particular color range. Faceting execution emphasizes parallel pavilion and crown facets, creating linear color flashes rather than strong scintillation, which is typical for a step cut and highly desirable for collectors who prioritize even color fields and a refined visual plane. Polish is excellent across all facet junctions, and symmetry is tight, which preserves the stone response under directional light while minimizing light leakage that could mute its intense hue.

Color and clarity define the personality of this stone. The sapphire exhibits intense color intensity, a saturated orangish yellow that reads golden with warm orange undertones under standard daylight and warm artificial illumination. The clarity is graded very very slightly included at the eye level, indicating that the stone appears eye clean to experienced observers, with only minute internal features visible under magnification and effectively invisible without magnification. This material has undergone beryllium diffusion enhancement, a stable high temperature treatment that introduces beryllium into the corundum lattice to shift the visible absorption edges and produce strong orangish yellow tones that are otherwise rare in the natural trace element palette. Technically beryllium diffusion modifies the chromium iron and titanium related chromophores and creates a penetrative color profile that often reaches near surface layers depending on diffusion parameters, so assessment under magnification will reveal characteristic diffusion zoning patterns rather than primary growth color zoning. The origin is Ceylon Sri Lanka, a source known for gem quality corundum with fine crystalline habit and clean host matrices, and the combination of Sri Lankan material quality and controlled beryllium diffusion gives an appealing marriage of natural crystal structure and engineered color precision.

In the context of famous gemstones and historic examples this sapphire occupies a distinct niche. Where the Tiffany Yellow Diamond and the Golden Jubilee Diamond are celebrated for their rare pure yellow hues in diamond material, this sapphire offers a different optical effect due to corundum dispersion and refractive index, producing a richer face up body color with a velvety saturation that diamonds cannot replicate. Compared to historic Ceylon sapphires such as the Logan Sapphire or the Star of India, which are renowned for large size and classic blue tones, this stone draws attention for color novelty and controlled saturation rather than sheer scale. The step cut evokes the dignified presence of rectangular cuts seen in many antique gems, but the intense orangish yellow color makes it more comparable in visual impact to famous yellow sapphires that have appeared in royal collections, while remaining highly wearable at its one point one eight carat weight. The result is a stone that is technically sophisticated in its cutting and polishing, precise in its color engineering through beryllium diffusion, and honest in provenance as a Ceylon origin sapphire, giving collectors and jewelers a reliably vivid center stone for bespoke designs. The Natural Sapphire Company presents this gem as an option for collectors who understand facet architecture and color science, and for designers seeking a statement center stone that balances historical gemstone storytelling with contemporary treatment transparency.
