0.98 Ct. Peridot from Ceylon (Sri Lanka)

This specimen is a transparent 0.98 carat round peridot, precisely measured at 6.21 x 6.10 x 3.87 millimeters, cut in a mixed brilliant configuration to balance depth of color with maximum light return. The mixed brilliant faceting marries a brilliant cut crown with a modified pavilion, creating a crisp interplay between large star and kite facets on the crown and a calibrated array of pavilion facets that channel light back through the table with controlled scintillation. The result of this profile is a lively, even face up brightness that benefits from the stone being evaluated as eye clean at normal viewing distance, so there is an unobstructed optical path through the pavilion and table for specular reflection and flash. Color grading for this item registers as vivid intensity, a saturated lime to slightly olive green typical of top Ceylon Sri Lanka peridot, and the stone shows an excellent polish, with facet junctions and facet planes executed to tight tolerances so that facet alignment and symmetry contribute to consistent sparkle across the table. Importantly, the gem is natural and untreated, no enhancement, which preserves the original saturation and crystal structure intrinsic to high quality Sri Lankan peridot, and confirms the material provenance indicated by The Natural Gemstone Company.

From a gemological perspective this peridot occupies a distinct optical niche among common green gemstones, due to its refractive and absorption characteristics, and the way a well executed mixed brilliant cut exploits those properties. Peridot typically has a refractive index in the range of approximately 1.65 to 1.69 and a birefringence around 0.036, with modest dispersion near 0.020, which means it will not show the intense fire associated with diamond, but it will produce very clear, lively scintillation and facet contrast when proportions and polish are optimal. Compared to diamond, which has a higher refractive index and dispersion, this peridot will not have the same white light return or spectral fire, however it compensates by offering a saturated green hue that remains vivid under varied lighting, something that colorless gemstones cannot provide. Against emeralds, which can have deeper green and richer saturation, this peridot stands apart by being eye clean and bright, without the strong inclusions and typical clarity treatments associated with many emeralds. Relative to tsavorite garnet and green tourmaline, which can present more refractive brilliance or slightly different tone, this peridot is notable for its unique lime to olive palette and the efficiency with which its mixed brilliant faceting converts internal light into lively, green flashes, a feature that appeals to connoisseurs seeking a transparent, intensely colored green that reads as fresh and vibrant in jewelry.

In practical terms the gemology and craftsmanship combine to make this 0.98 carat round peridot a versatile choice for custom settings, from solitaire rings to delicate pendants and fine earring pairs, and its dimensions allow predictable bezel or four prong mounts while maintaining optical performance. Given peridot hardness around 6.5 to 7 on the Mohs scale, I recommend protective settings for everyday wear to minimize abrasion and to avoid exposure to harsh chemicals and prolonged high heat, which can affect surface polish over time, and professional cleaning should be done with warm soapy water and a soft brush rather than ultrasonic methods. The mixed brilliant proportions here are intentionally calibrated to balance table size and pavilion depth in order to maximize both color saturation and light return, so choosing yellow or rose gold settings will warm the perceived hue and emphasize the olive tones, while white gold or platinum will produce a fresher lime contrast, depending on design intent. As specialists, The Natural Gemstone Company provides detailed images and measurements for careful evaluation, and we confirm the stone is natural, eye clean, vividly colored, and unenhanced, origins traceable to Ceylon Sri Lanka, with excellent polish and precision faceting.
