1.08 Ct. Yellowish Green Sapphire from Nigeria

This transparent asscher octagon yellowish green sapphire weighs one point zero eight carats, and measures five point one five by five point zero seven by three point nine six millimeters. The outline is a true asscher octagon, with a square footprint and clipped corners that create an elegant octagonal silhouette. The asscher cut is executed with a classic step faceting schema, featuring concentric square facets on the crown, a broad table plane calibrated for even light entry, and deep, well angled pavilion steps arranged to produce a hall of mirrors effect. The near perfect symmetry of the facet pattern is immediately apparent at a loupe and at the naked eye, the facet junctions are crisp, and the alignment of the step facets preserves the geometry expected of high quality asscher cutting. The Natural Sapphire Company presents this gem as an example of exacting cutting practice combined with a pleasing, compact set of proportions suited for a variety of fine jewelry settings.

The cutting proportions yield a depth relationship that emphasizes color saturation and internal light play. The stone depth of three point nine six millimeters relative to the mean diameter gives an overall depth ratio of approximately seventy seven point five percent, a proportion that favors strong color return and pronounced internal contrast rather than rapid scintillation. The asscher step design converts incoming light into broad flashes and layered reflections, the result is an interplay of planes that accentuates the stone tone, and that renders the intense color intensity as a primary visual feature. Facet angles were set to optimize light return for this particular material, allowing the yellowish green hue to appear evenly distributed across the table and crown, and avoiding windowing that can desaturate color. The polish is excellent throughout, with mirror like facet surfaces that enhance both color and reflectivity, and the girdle has been finished to a consistent thickness for secure setting, while maintaining minimal weight loss from preform to finished gemstone.

Clarity has been assessed as very slightly included at eye level, which indicates that the stone retains a high degree of visual purity with small natural features that do not compromise aesthetic appeal. The very slight inclusions are oriented so as to be unobtrusive in typical viewing positions, they serve as natural fingerprints of formation rather than detractors, and they allow the cutter to balance clarity preservation against yield. Importantly, this sapphire exhibits no enhancement, it is offered untreated, preserving the integrity of the corundum crystal chemistry. The origin is Nigeria, a source that has produced sapphires with unique and desirable hues, due to the specific trace element composition and growth conditions of local deposits. Collectors and connoisseurs will value the combination of intense color, natural clarity character, and verified origin, all of which align with traditional criteria for untreated corundum acquisition.

Beyond its material metrics, this sapphire carries a lineage tied to historical uses of green and yellow corundum tones, which have been employed for centuries as personal talismans and signet stones, and as focal gems in rings and pendants intended to convey prosperity, vigilance, and longevity. Step cut stones such as this asscher frequently appear in period jewelry, where the architectural faceting harmonizes with classical mounts and signet style settings. For the knowledgeable buyer, the technical virtues of this gem make it suitable for precision settings that highlight facet geometry, such as closed basket bezels, step motif halo arrays, or hand fabricated mounts that echo the square octagonal outline. The Natural Sapphire Company invites buyers who appreciate technical exactitude and historical resonance to consider this stone as an opportunity to own a rare combination of untreated origin, intense hue, meticulous asscher cutting, and museum quality polish.
