21.27 Ct.Tw.Total Carat Weight Green (Lime Green) Peridot Pair from Ceylon (Sri Lanka)

This matched pair of peridot gemstones from Ceylon is presented with clear technical specification and measured optical performance, the left stone weighing 10.92 carats and the right stone weighing 10.35 carats, each cut to an oval outline with dimensions of 17.97 by 10.74 by 7.38 millimeters and 17.99 by 10.72 by 7.01 millimeters respectively. Both stones display a vivid lime green hue with consistent saturation across the tables, and they are graded as eye clean under typical visual inspection, indicating negligible inclusions that could disrupt light transmission. The mixed brilliant cut profile combines a well proportioned crown with a faceted pavilion, producing efficient return of light aided by an excellent polish, and no enhancement has been applied to alter color or clarity. As natural olivine, these peridots exhibit a refractive index in the range of approximately 1.65 to 1.69 and a measurable birefringence near 0.036, optical properties that support lively internal reflections and crisp facet delineation while maintaining a steady overall brightness.

When viewed as a pair, the two stones demonstrate complementary reflective behavior that enhances their collective presence, the slightly greater depth of the larger stone produces stronger contrast and deeper pavilion reflections, while the marginally shallower profile of the companion stone yields broader, more expansive flashes across the crown facets. The mixed brilliant facet arrangement in both gems creates coordinated light paths, so that facet junctions reflect light in phase and produce matched scintillation when set side by side, and the eye clean clarity ensures that these returns are uninterrupted by reaching inclusions. The vivid lime green color interacts with the facet generated reflections to deliver a dynamic range from lively yellowish green highlights to more saturated olive green zones, the variation increases perceived depth and prevents a flat appearance when the stones are paired. In practical application these characteristics make the pair especially suitable for symmetrical settings where balanced light performance is desired, such as mountings for earrings or matched centerpieces, and The Natural Gemstone Company confirms that the stones are natural Sri Lankan peridot specimens, untreated, and presented with polish and cutting that optimize their innate reflective qualities.
