9.12 Ct. Green (Lime Green) Cabochon Peridot from Pakistan

This listing presents a single, translucent peridot, weight 9.12 carats, fashioned as a round cabochon with precise dimensions 12.93 by 13.03 by 5.80 millimeters, color described as a vivid lime green and color intensity evaluated as intense, polish graded excellent, clarity graded slightly included at eye level, enhancement none, origin Pakistan, supplied by The Natural Gemstone Company. Peridot is a gem-quality member of the olivine group, crystallographically orthorhombic with typical refractive indices in the range of approximately 1.654 to 1.690, a birefringence on the order of 0.036, an average specific gravity close to 3.2 to 3.4 and a Mohs hardness near 6.5 to 7. These physical constants explain the stone s lively internal dispersion and the way the cabochon dome interacts with incident light, producing the saturated, peppered lime tone characteristic of high quality Pakistani peridot material.

The cabochon cut employed here is a deliberate lapidary choice to maximize the peridot s translucence and broad color face, rather than faceting for brilliance. The gently domed profile and symmetrical round outline emphasize uniform color distribution and permit deep visual inspection of the internal structure without the distraction of facet reflections. At 5.80 millimeters in height the dome is substantial enough to create a pronounced window effect, allowing light to penetrate and scatter within the stone s body while maintaining a smooth, continuous surface geometry that exhibits the excellent polish noted in the grading. The lapidary work demonstrates controlled symmetry and a consistent girdle, attributes that facilitate secure mounting, predictable light return, and comfortable wear. Because peridot is moderately hard, the cutter s choice of a rounded bezel-compatible shape represents a balance between aesthetic presentation and practical durability for jewelry applications.

Inclusions in this specimen function as natural identifiers and contribute materially to the gem s personality and provenance. Under straightforward loupe or eye-level observation the stone shows fine, hairline filamentary inclusions and a network of thin healed fissures that present as delicate linear features and slender, darkened needle-like elements dispersed beneath the dome. These internal features are consistent with natural peridot s crystallization environment and are not structural faults that compromise the overall stability of the gem in normal wear when set appropriately. The slightly included clarity grade at eye level acknowledges that these inclusions are visible without magnification, yet they also serve as a reproducible internal map that can be used to identify this specific piece against similar material, to document origin, and to authenticate the stone as untreated. The inclusions create subtle textural depth, producing micro-contrast within the lime color and yielding a three-dimensional vitality that many collectors and designers prize as a marker of natural formation rather than as an aesthetic defect.

Practical considerations for design and care arise directly from the gem s measured attributes and internal characteristics. At 9.12 carats and a compact 13 millimeter diameter, this cabochon is well suited to statement rings, pendant centers, or a bespoke bezel set where the rounded girdle and polished dome can be protected from edge knocks, since peridot s Mohs hardness indicates susceptibility to abrasion and the present healed fissures suggest caution with ultrasonic or steam cleaning. We recommend routine cleaning with warm, soapy water and a soft brush, and avoidance of harsh chemical exposure and blunt impacts. The natural, untreated origin from Pakistan enhances collectability and provides provenance value for connoisseurs seeking authentic material. For documentation and secure transaction, The Natural Gemstone Company records the dimensional, weight, and optical data and will supply additional detailed imagery or inclusion mapping upon request. This peridot s intense lime hue, robust cabochon profile, and unique internal fingerprint make it an excellent candidate for designers and collectors who prioritize natural character and verified craftsmanship.
