8.38 Ct. Cabochon Lapis from Afghanistan

This specimen is a pristine 8.38 carat cushion shape blue lapis, presenting compact proportions at 12.06 by 12.01 by 8.49 millimeters, originating from Afghanistan. The cutting style is a traditional cabochon, executed in a sugar loaf profile that emphasizes a tall central dome and a gently curved pavilion. The material is opaque, carrying a rich ultramarine to royal blue tone, with color intensity recorded as not applicable given the cabochon presentation and the complex matrix typical of natural lapis. The surface finish is of excellent polish, producing a deep, satiny reflection that enhances the stone for close inspection and photographic documentation. There has been no enhancement, no dyeing, and no resin filling applied to this piece, a fact we certify at The Natural Gemstone Company.

From a lapidary standpoint this cabochon demonstrates disciplined preforming and controlled dome shaping, which are critical to the sugar loaf style. The cutter has maintained a consistent crown radius across the cushion outline, preserving optical depth while avoiding high points that would be vulnerable in setting. The transition from crown to girdle is smooth and even, reflecting progressive sanding stages through increasingly fine abrasives, and a final polish executed with an oxide compound suited to the low to moderate hardness of lapis. The cutter allowed for slight retention of natural surface undulation near the base, a deliberate choice that reduces material loss while preserving matrix character. The result is a stable, wearable cabochon that balances maximum color saturation with structural integrity for bezel or prong mounting.

Inclusions within this lapis are noteworthy and serve as intrinsic fingerprints for provenance and individuality, rather than as detractors. The stone exhibits subtle white calcite veining distributed near the pavilion edge, and intermittent microscopic pyrite microinclusions imparting faint metallic speckle in certain light angles. These features are consistent with classic Afghan lapis deposits, where nodular growth of lazurite occurs alongside calcite and disseminated pyrite. The calcite creates soft tonal variegation that breaks the uniformity of blue, while the pyrite provides tiny points of luster that contrast with the overall satiny polish. Under magnification these inclusions form non repeating patterns, which gemologists can map for identification and which collectors value as natural signatures. The inclusion pattern also affects light interaction, generating localized contrast that enhances perceived depth in the dome profile.

For practical use and appraisal, consider the physical and aesthetic behavior of this lapis in wearable form. Lapis has moderate surface hardness and benefits from protective bezel settings if used in daily wear rings, while more open settings are appropriate for pendants or brooches that reduce abrasion risk. The weight to size ratio and the tall sugar loaf dome produce a strong face up presence on the finger or in a pendant, and the cabochon shape will show the interplay of calcite and pyrite when viewed under directional light. Routine care is straightforward, using a soft cloth and mild detergent for cleaning, avoiding ultrasonic or steam methods that could stress the matrix. As representatives of The Natural Gemstone Company I affirm the natural origin, lack of enhancement, and careful lapidary work on this cushion cabochon, and we welcome technical inquiries or requests for matching stones, custom mounting advice, or detailed inclusion photographs for condition and provenance documentation.
