5.81 Ct. Lapis from Afghanistan

This piece is a 5.81 carat cushion shape lapis, measuring 16.11 by 12.11 by 2.78 mm, exhibiting an opaque body with a pronounced purplish blue hue. The color is best described as vivid intensity, with a strong saturation that reads richer in hand than in typical online images, and with minimal calcite wash which preserves the depth of tone. The tablet cut emphasizes a flat to low domed profile, allowing the eye to appreciate the uniformity of the color plane and the distribution of accessory minerals. Surface specks of metallic pyrite appear as fine golden flecks aligned in a subtle linear pattern, adding visual contrast without distracting from the primary blue field. No enhancement has been applied, the stone is in natural condition, and the origin is Afghanistan, a classic provenance for high quality lapis that informs both the material characteristics and market desirability. The weight and proportions yield a substantial face up area for use in statement rings, pendants, or artisanal inlay work, and the overall visual balance between size and thickness supports stable setting options.

From a lapidary perspective the tablet cut executed on this specimen demonstrates deliberate control of form and polish, reflecting experienced preforming and finishing technique. The cushion outline was carefully planned to align the longest dimension with the best color banding, reducing the need for aggressive removal of material and preserving carat weight. The cut maintains gentle beveling along the edges to prevent chipping in setting, while the flat plane is finished to a high degree of planarity, producing even light absorption and minimal surface distortion. Polishing progressed through a graded sequence of abrasives, finishing with a fine oxide polish to achieve an excellent polish grade across the table and around the girdle. This approach retains microtexture that contributes to a pleasing tactile quality, while eliminating microscopic scratches that would otherwise scatter light and diminish perceived color saturation. The absence of facets in a tablet cut intentionally emphasizes color continuity, so the lapidary decision matrix prioritized color conservation over faceted sparkle, an approach that benefits collectors and designers who seek intense, uniform color in opaque materials.

In practical use the material benefits from consideration of lapis physical properties, including a Mohs hardness in the range of five to five and a half, and a specific gravity typically between 2.7 and 2.9, factors that influence setting method and day to day wear. Because lapis is softer than traditional gemstones used in rings, secure bezel settings or protective mountings are recommended for frequent wear, while prong settings can be employed when paired with a robust protective bezel rim to prevent edge damage. The tablet cushion profile lies comfortably in settings that require a low profile, and the even plane permits precise adhesive or peen mounting for inlay applications. Care instructions include avoidance of acids and prolonged exposure to ultrasonic cleaning, and a regimen of gentle cleaning with mild detergent and a soft brush to maintain the polish. The Natural Gemstone Company offers this lapis as a natural, untreated specimen that is suitable for collectors and fine jewelry designers who prioritize provenance and craftsmanship.
