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

One beautiful transparent 2.85 carat oval shape lime green peridot, measuring 10.00 x 7.87 x 5.36 mm, offers a compelling combination of size and visual performance for an informed collector, the gem is fashioned in a mixed brilliant cut, the crown carries brilliant style facets that maximize return of light, while the pavilion is arranged to emphasize depth and scintillation, the clarity is graded slightly included when evaluated at eye level, indicating minor internal features that do not significantly detract from face up appeal, the color intensity is described as intense, the polish is excellent, the stone has been heat treated, and the recorded origin is Ceylon, Sri Lanka, an origin prized for producing lively colored peridot, The Natural Gemstone Company presents this peridot with full, transparent disclosure of its characteristics and enhancements.

The structural reasons this peridot displays a sparkle that stands out begin with its crystal chemistry and optical properties, peridot is the gem quality variety of olivine, a magnesium iron silicate with an orthorhombic crystal structure, this arrangement produces relatively high refractive indices in the range typical for peridot, along with notable birefringence, the combination of a higher refractive index and controlled birefringence allows facets to capture and split light in a way that produces lively internal reflections and pronounced facet contrast, the mixed brilliant cut further exploits these properties by using a brilliant facet pattern on the crown to refract light back through the table while the pavilion facets redirect light to enhance scintillation, the intense lime green color benefits from the cut geometry by giving a strong, even face up hue that competes with larger stones of muted tone, the slightly included clarity is consistent with natural peridot material and is often acceptable to educated buyers because inclusions are generally minor and can confirm natural origin, heat treatment is disclosed and is a stable, commonly accepted enhancement that can improve color uniformity without compromising structural integrity when performed appropriately, provenance from Ceylon adds market interest due to the island reputation for fine colored gems, for a discerning purchaser this peridot represents a technically sound combination of optical performance, precise cutting, and transparent grading, The Natural Gemstone Company stands behind the description and is available to provide additional laboratory reports or magnified imagery upon request.
