2.99 Ct. Green (Lime Green) Peridot from Ceylon (Sri Lanka)

This 2.99 carat oval peridot from Ceylon presented by The Natural Gemstone Company exhibits disciplined proportions and meticulous execution, dimensions 10.05 by 8.07 by 5.35 millimeters giving a depth ratio of approximately 53.2 percent and a length to width ratio of about 1.25, proportions that preserve face up size while allowing the pavilion to return light efficiently. The stone is cut in a mixed brilliant style, featuring a brilliant faceted crown paired with a modified pavilion, an arrangement selected to maximize scintillation and maintain crisp facet junctions across the table and upper girdle facets. Facet arrangement and symmetry are executed to tight tolerances, the excellent polish producing smooth facet planes that enhance internal reflection and minimize light leakage. The color is intense lime green, the chroma concentrated and evenly distributed through the body color, the hue produced by iron chromophores and stabilized by controlled heat treatment. Clarity is slightly included at eye level, with minute inclusions that do not impede transparency or the overall performance of the cut, and the stone carries a professional finish consistent with precision lapidary techniques often reserved for top grade specimens.

When comparing brilliance to more common gemstones the optical behavior of this peridot is notable for its combination of refractive index, dispersion, and birefringence, refractive index approximately 1.65 to 1.69 and birefringence near 0.036, values that yield a lively internal play distinct from lower index gems such as quartz and more transparent than many emeralds, which commonly suffer reduced face up brilliance due to inclusions. Against diamonds, peridot does not match the extreme dispersion or brilliance of a diamond, however the mixed brilliant cut optimizes light return for peridot s optical window and produces a different, highly attractive kind of scintillation, one characterized by crisp lime flashes and directional sparkle rather than high fire. Compared to sapphires and spinels the peridot s lighter tone and intense chroma make its brilliance feel more vivid in daylight, and the measured pavilion depth and table proportions in this piece ensure strong contrast and attractive windowing control. For the connoisseur seeking a gem with technical refinement, unique optical character, and conscientious lapidary finishing, this peridot is a refined choice from The Natural Gemstone Company, offering both collectible quality and wearable brilliance.
