15.66 Ct. Cabochon Lapis from Afghanistan

This entry presents a single, well proportioned lapis lazuli specimen, offered with precise attributes for evaluation. The gem weighs 15.66 carat, and is fashioned in a cushion shape, presenting an even outline and balanced proportions. The material is opaque, exhibiting the characteristic deep blue of fine lapis, and it displays a vivid color intensity that remains consistent across the table and crown. The cut is a cabochon, selected to maximize the rich blue field and to present a smooth, gently domed face. The overall appearance is refined, with no surface treatments applied, and the gem retains its natural state as documented.

The dimensions of this cushion cabochon are 15.84 x 13.96 x 7.63 mm, suitable for a range of mounting styles that accommodate a slightly stout profile and a secure bezel or prong setting. The profile height of 7.63 mm provides a pleasing dome that will read as substantial when set in rings, pendants, or small brooches. The cabochon cut has been executed to present an even curvature, with balanced slopes on all sides, and the girdle transition is smooth to the touch. The weight distribution at 15.66 carat corresponds well to the stone proportions, and the dimensions align with standard jewelry manufacturing tolerances.

Surface polish and internal character are important considerations for this lapis. The finish is described as excellent polish, producing a strong, lustrous sheen across the dome that enhances the perceived depth of color. Internal matrix and pyrite inclusions can vary in lapis, and in this specimen the surface shows minimal matrix disruption, with the blue matrix dominant and uniform. No enhancement has been applied, so the color and surface condition are wholly natural. The origin of the material is Afghanistan, a source known for producing classic intense blue lapis with a historical provenance. The combination of vivid natural color, cabochon form, and the absence of treatment supports its classification as a quality lapis specimen.

For practical application and handling, the gem is suitable for fine jewelry settings that emphasize the stone color and silhouette. The cushion cabochon format favors bezel settings and low profile mounts that protect the dome, and the opaque nature of the material allows for secure closure without concern for light performance. Routine care involves gentle cleaning with a soft cloth, lukewarm water, and mild soap, avoiding ultrasonic cleaners and harsh chemicals that could affect natural surface characteristics. The Natural Gemstone Company provides this lapis as a natural, untreated example for designers and collectors seeking authentic Afghan material, and full provenance and measured specifications are available upon request to facilitate integration into design and appraisal workflows.
