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

This peridot presented by The Natural Gemstone Company is a sizable transparent specimen weighing 29.95 carat, with precise proportions of 21.02 x 16.93 x 10.15 mm in an oval outline. The cutter executed a double cabochon form, a full taille dome that is mirrored on both crown and pavilion, which in this material optimizes internal light return and body color without introducing faceted reflections. Color is a vivid lime green with medium intensity, evenly distributed across the surface owing to the relatively deep pavilion height of 10.15 mm, which increases optical path length and enhances absorption by iron chromophores that produce the characteristic peridot hue. Clarity is graded very slightly included when evaluated at eye level, with minute inclusions that do not interrupt transparency or create significant light obstruction, and the overall finish is described as excellent polish, yielding smooth curvature and crisp, specular reflections across the dome.

From a gemological perspective this peridot exhibits the expected physical and optical parameters for olivine group material, and this informs both appearance and handling. Refractive index falls in the typical range for peridot, and birefringence of approximately 0.036 to 0.038 can subtly influence edge definition on highly domed surfaces, though the double cabochon form here renders that effect benign and often visually pleasing. Specific gravity near 3.3 means the stone carries substantial weight relative to size, consistent with the near 30 carat mass reported. Hardness on the Mohs scale is approximately 6.5 to 7, which allows everyday wear in protected settings, but also necessitates mindful design to avoid abrasion and impact. This example is natural, with no enhancement, and its Pakistani origin contributes to the geographic identity that collectors and connoisseurs recognize as producing clean, saturated green peridot crystals.

Practical considerations for deployment and long term preservation are based on the material and the cut geometry. The double domed profile and generous thickness make this specimen ideal for bezel, closed back, or custom gallery settings that protect the girdle and edges while allowing the dome to present as a color window. A flush or partial bezel will reduce the risk of chipping and distribute mechanical stress across the metal rather than on the stone perimeter. Because peridot can be vulnerable to thermal shock and to prolonged exposure to household chemicals, cleaning recommendations are gentle manual washing with warm water and mild detergent, avoiding steam and ultrasonic cleaners. For jewelry production we advise seat design that accommodates the 10.15 mm depth and secures the stone with a supporting seat to prevent flexing. For clients seeking certification or provenance documentation, The Natural Gemstone Company can provide measured grading details and photographic documentation, and we can arrange third party laboratory reporting for trade or insurance purposes. This peridot is well suited to collectors and bespoke jewelry commissions where natural color, substantial carat weight, and meticulous lapidary workmanship are valued.
