0.79 Ct. Green (Lime Green) Peridot from Pakistan

This transparent 0.79 carat cushion shape peridot from Pakistan presents a fresh lime green hue with medium color intensity, a clean overall appearance to the naked eye, and no indications of treatment or enhancement. The measured dimensions are 5.70 by 4.93 by 4.27 millimeters, and the stone is offered by The Natural Gemstone Company as a single, natural specimen with an excellent polish. The cushion outline favors soft rounded corners and a well balanced silhouette, allowing the lively lime green tone to read clearly even in smaller finger sizes, while the absence of enhancement preserves the gemological integrity and natural appeal of the material. The provenance from Pakistan aligns with the geological character of peridot sourced from high grade mantle nodules, and the color palette here leans toward the lighter, vivid spectrum that peridot collectors and jewelry designers often seek.

The cutting style is a mixed brilliant configuration optimized for a cushion plan, with a brilliant oriented crown that transitions into a modified pavilion geometry to maximize scintillation and preserve weight. The mixed brilliant approach places smaller, carefully proportioned star and kite facets on the crown to enhance return from the table, while the pavilion uses a combination of triangular and irregular facets to disperse light and reduce pronounced windowing. Based on the provided dimensions the calculated depth is approximately 4.27 millimeters, which corresponds to a depth percent near 80 percent when referenced to the average girdle diameter, a proportion that is deeper than typical for modern cushion cuts. That additional depth concentrates color and can increase apparent saturation when viewed face up, but it also places greater emphasis on pavilion facet alignment and symmetry, so the cutter compensated with precise facet junctions and an excellent polish to maintain lively brilliance and avoid dead areas.

Clarity is graded as slightly included at eye level, a realistic description for peridot where small chromite crystals and isolated particulate inclusions are common and diagnostic. These internal features are stable within the host olivine structure, and they contribute to a natural fingerprint that is often acceptable to connoisseurs because they do not substantially impede transparency or sparkle in this example. From a gemological perspective peridot exhibits a refractive index range approximately 1.65 to 1.69, birefringence in the order of 0.036, a specific gravity near 3.30, and modest dispersion, characteristics that create a crisp, lively look when facets are well executed. The cutter achieved excellent polish across all facet planes, which optimizes the refractive behavior and enhances visual contrast between the bright facets and the subtle internal texture.

When considering durability, peridot rates about 6.5 to 7 on the Mohs scale, which places it below corundum and diamond in hardness, comparable to or slightly softer than quartz, and appreciably softer than topaz, sapphire, and ruby. This means the gem is suitable for many types of jewelry, but it benefits from protective mounting strategies for pieces subjected to daily wear, such as rings. A bezel or elevated claw design that shields the girdle and corners will reduce the risk of edge chipping, and routine care should favor gentle cleaning with warm soapy water and a soft brush rather than ultrasonic or steam cleaners which can stress inclusions or the mounting. For buyers and designers working with The Natural Gemstone Company this peridot blends collectible natural origin, considered cutting tradeoffs that enhance color saturation, and practical care guidance, making it a technically interesting and wearable choice for fine jewelry applications.
