2.57 Ct. Green (Lime Green) Peridot from Pakistan

This 2.57 carat radiant shaped peridot, supplied by The Natural Gemstone Company, is a study in calculated geometry and optical performance. The radiant outline, with its truncated corners and compact rectangular proportions measuring 8.78 by 6.83 by 5.37 millimeters, is faceted using a mixed brilliant and step pattern that promotes maximum light play. The precision of the pavilion facets and the interplay between crown brilliance and step facets direct light back through the table and crown, producing scintillation and a lively internal flash that enhances the stone's medium lime green hue. The fancy cut and excellent polish further refine surface reflectivity, minimizing light leakage and allowing the peridot to exhibit crisp facet junctions and consistent brightness across the table. As peridot is an orthorhombic olivine with a refractive index typically in the 1.65 to 1.69 range and birefringence up to approximately 0.036, this cutting style amplifies the gem’s inherent optical characteristics so that color and sparkle remain pronounced in most lighting environments.

From a connoisseur’s perspective, this gem’s grading and origin details are materially important. The peridot is transparent with a clarity grade noted as slightly included at eye level, meaning minor inclusions are present and can be observed without magnification under certain viewing angles, yet they do not significantly interrupt the gem’s overall transparency or diminish its brilliance. These inclusion characteristics are common in peridot and often serve as natural fingerprints that confirm a gem’s authenticity. The medium color intensity offers a true lime green that is highly desirable for collectors seeking vivid yet balanced tones, and crucially, the stone has undergone no enhancement, providing assurance of natural state and long term stability. Originating from Pakistan, a known source of gem-quality peridot, this specimen benefits from geological conditions that yield distinctive green saturation. For an educated buyer, the combination of a substantial 2.57 carat weight, an optimized radiant faceting that preserves weight while maximizing return of light, an excellent polish, and natural, untreated origin makes this peridot an attractive acquisition both for investment and for use in fine jewelry settings where the cut will display its optical strengths.
