0.90 Ct. Green (Lime Green) Peridot from Pakistan

This specimen is a transparent 0.90 carat oval peridot, with dimensions 7.12 x 5.08 x 3.35 millimeters, exhibiting a vivid lime green hue with medium color intensity, very slightly included clarity evaluated at eye level, excellent polish, and no enhancement, originating from Pakistan. The cutter selected a mixed brilliant strategy to marry high brilliance with controlled color saturation, employing a brilliant facet arrangement across the crown to maximize return of white light, while utilizing step oriented pavilion facets to strengthen color retention and depth. The proportions are carefully balanced, with a measured depth of approximately 55 percent relative to the average of length and width, producing an optimized face up appearance that balances spread with depth, and a table proportion that preserves scintillation without sacrificing color. Facet junctions are crisply executed and symmetry is precise, the result of meticulous lapidary control that minimizes windowing and ensures lively facet contrast across the oval outline.

Optically this peridot benefits from the gemology of olivine group material, with an effective refractive index range near 1.65 to 1.69, and birefringence on the order of 0.036 to 0.039, characteristics that give peridot its characteristic brilliance and subtle doubling under magnification, while the mixed brilliant cut mitigates visual dispersion anomalies and presents a uniform lime green tone to the observer. Specific gravity falls in the typical range of 3.27 to 3.37, contributing to a satisfying heft for its carat weight, and the gem exhibits the orthorhombic crystal habit typical of quality peridot. The excellent polish enhances light return and face up brightness, while the very slightly included clarity grade, assessed at eye level, means inclusions are minimal and do not interfere with performance, allowing clean light pathways and consistent brilliance. The natural, untreated origin from Pakistan is evidenced by the characteristic iron content and crystal habit, ensuring that color and transparency are intrinsic to the material rather than the result of enhancement.

When considering daily wear, this 0.90 carat peridot combines practical durability with refined lapidary technique to make it an excellent candidate for frequently worn jewelry. Peridot has a Mohs hardness in the vicinity of 6.5 to 7, which places it above many common materials used in jewelry but below the hardest gemstones, therefore appropriate protective design is important, however in practice a well cut and well polished peridot such as this one performs exceptionally in settings that shield edges and the girdle. The cutter has preserved a moderately thick girdle and robust depth, enhancing structural integrity, and the mixed brilliant facet plan reduces stress concentration by avoiding excessively thin facets. For daily wear we recommend protective mountings such as bezel, partial bezel, or halo prong systems that guard the girdle and culet, avoiding situations of high lateral impact. Routine care is straightforward, warm soapy water and a soft brush are ideal to maintain brilliance, avoid ultrasonic cleaners and harsh chemicals, and remove the piece for heavy manual work to prevent mechanical damage given natural cleavage tendencies.
