8.22 Ct. Cabochon Lapis from Afghanistan

This oval cabochon is a technically precise example of classic lapis craftsmanship, weighing 8.22 carats with dimensions of 16.85 by 14.10 by 4.21 millimeters. The cutting style is cabochon, executed to emphasize the stone s surface face up color and internal accessory mineralogy rather than light return through faceting. The dome height and curvature have been balanced to provide an even visual field across the oval outline, while the girdle flow remains consistent for secure bezel setting. Polish is assessed as excellent, producing a high gloss face that enhances the perception of depth in the body color and allows the pyrite inclusions to reflect discreetly without causing glare. The material is opaque, and enhancement is none, confirming that the blue saturation and the distribution of pyrite are entirely natural, attributable to the stone s origin in Afghanistan. As lapis is a composite rock dominated by lazurite with accessory calcite and pyrite, the lapidary choices in this piece prioritize surface smoothness and uniformity of tone, preserving the natural interplay of ultramarine chroma and metallic speckling.

Color analysis for this Afghan lapis focuses on hue, tone, and saturation, and how these attributes compare to lapis from other well known localities and to iconic blue gemstones. The hue of this cabochon registers as a deep, true ultramarine blue with a slight purplish bias in certain light angles, and the tone sits in the medium dark range, providing strong presence without approaching blackish notes. Saturation is high for a natural lapis, which produces a vivid face up that reads more intensely than typical Chilean material. Compared to Chilean lapis, which is often lighter, more azure, and commonly shows higher calcite content that creates whitish veining or a washed out appearance, this Afghan example shows markedly less calcite and a denser distribution of lazurite, resulting in a cleaner field of blue. Russian and Siberian lapis examples can approach similar depth, but Russian stones frequently exhibit very uniform coloration with fewer pyrite inclusions, presenting a velvety homogeneous blue that differs from the subtly variegated texture evident here. For buyers familiar with corundum sourced from Kashmir or Sri Lanka, the comparison is useful to illustrate differences in medium, rather than to equate gemstones, because Kashmir sapphires deliver translucent cornflower tones with velvety light scattering, whereas this Afghan lapis delivers an opaque, saturated ultramarine plane punctuated by metallic pyrite points, a visual effect unique to lapis.

From a craftsmanship and design perspective, this oval 8.22 carat cabochon is ideal for applications where the surface and natural inclusions are the focal point, and where a stable setting can protect the stone s moderate hardness. The dimensions and even dome suggest reliable performance in bezel and halo settings, with the 4.21 millimeter depth offering sufficient material for secure mounting without excessive bulk, making it suitable for statement rings, pendants, and bespoke brooches. The excellent polish enhances wearability and visual impact, while the lack of treatment preserves the collector value associated with natural Afghan lapis, recognized historically as the benchmark for ultramarine quality. Practical considerations for jewelers include recommending a low impact mounting to minimize exposure to solvents or harsh cleaning methods, and advising clients about the stone s relative sensitivity to abrasion compared with harder gems, while noting that routine care with a soft cloth will retain the polished luster. At The Natural Gemstone Company we document origin and treatment status because provenance and technical disclosure are essential to informed purchasing decisions, and this cabochon is presented as a natural Afghan lapis, untreated, expertly shaped, and ready for incorporation into refined jewelry where its intense ultramarine hue and measured pyrite sparkle will be the defining visual element.
