0.56 Ct. Green (Lime Green) Peridot from Tanzania

This peridot offered by The Natural Gemstone Company is a precision executed, transparent 0.56 carat emerald cut, with calibrated dimensions of 5.77 by 4.36 by 2.70 millimeters, originating from Tanzania. The stone displays an intense lime green hue, with color saturation deliberately preserved by the step cut geometry to emphasize uniform color windows rather than dispersed spectral fire. The clarity grade is slightly included, evaluated at eye level, and these minor natural features are consistent with peridot crystal habit and do not compromise the gemological integrity. The piece has received no enhancement, and it retains its natural chemistry and optical properties, with a refractive index in the expected peridot range around 1.65 to 1.69, and a birefringence on the order of 0.036, factors that directly inform its optical performance. The measured proportions yield a depth percentage of approximately 53.4 percent, a figure that is deliberately chosen to balance pavilion depth with table size, optimizing internal light return while maintaining the hallmark elongated silhouette of the emerald cut.

The emerald cut faceting plan is executed to technical exactness, employing parallel step facets on both the crown and pavilion to create broad, directional flashes of light and a hall of mirrors effect that is distinctively suited to peridot. Instead of relying on high dispersion to generate fire, this peridot exploits its moderately high refractive index and measurable birefringence to produce doubled facet reflections and crisp internal flashes when light traverses the orthorhombic crystal lattice. Precision in facet angles and facet junctions is critical for this outcome, and the gem displays symmetry that aligns crown facets to pavilion facets with minimal offset, enabling coherent light channels and elongated flash patterns along the length of the stone. The excellent polish enhances surface transmission, reducing micro abrasions that scatter light, and yields sharp facet delineation that intensifies the perceived brilliance. The result is a sparkle that is measured and architectural, characterized by linear flashes, mirror like planes, and a lively internal scintillation that changes with viewing angle, an effect that is both distinctive and unmatched among step cut gems of this scale.

From a craftsmanship and setting perspective, this 0.56 carat peridot is engineered for maximum visual impact when mounted in fine jewelry, especially in designs that showcase the table and the step facets, such as solitaire ring settings with four or six prongs, bezel frames that protect edges while revealing the crown, or custom east west mounts that accentuate its rectangular geometry. The slightly included clarity grade evaluated at eye level indicates natural inclusions that are minor and characteristic, and under controlled faceting they contribute to the gemological story rather than detract from optical performance. The absence of enhancements preserves both the gemological authenticity and the long term stability of the stone, and Tanzanian provenance adds a geographical signature recognized for producing vibrant lime green peridot crystals. At The Natural Gemstone Company we apply rigorous metrology and hand finishing, verifying proportions, polish, and symmetry to ensure each facet contributes to optimum light return, and we provide detailed documentation on origin, treatment, and measured proportions. This peridot is ideal for the discerning buyer seeking a technically refined gemstone that delivers a sophisticated, structure driven sparkle, and our team is available to discuss mounting options, certification specifics, and any technical questions to ensure a perfect match to your design intentions.
