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

This exquisite transparent peridot from The Natural Gemstone Company weighs 2.74 carat, and is fashioned in a classic cushion shape with measured dimensions of 9.54 x 7.18 x 5.39 millimeters. The cutter selected a mixed brilliant facet scheme to marry the scintillation of brilliant facets with the color retention and elegance of step facets. Color is a fresh lime green with medium intensity, a hue that reads lively under both natural and artificial lighting. Clarity has been assessed as slightly included at eye level, an honest and typical grade for peridot of this size that nevertheless presents a clean face up appearance. The polish is excellent, and the stone is natural with no enhancement, an attribute that discerning buyers and connoisseurs prize for its authenticity and long term value. The origin is recorded as Ceylon, Sri Lanka, a classic source that has produced many fine peridot specimens and contributes provenance to the gem.

The peridot family is a gem variety of the olivine group, composed primarily of magnesium iron silicate, and it is that specific crystal chemistry and internal structure that create the peridot sparkle which is distinct from that of many other green gems. Peridot crystallizes in the orthorhombic system, producing well defined cleavage and facetable planes that cutters can exploit to optimize internal reflection. The gem displays a refractive index typically in the range of 1.65 to 1.69, which is high enough to produce strong light return, and it exhibits measurable birefringence that contributes to an attractive doubling of facet edges under magnification. These optical properties, combined with a modest dispersion, yield a lively combination of broad flashes of light and crisp scintillation, especially when a mixed brilliant cut is applied to a well proportioned stone such as this example.

From the point of view of gem grading and connoisseurship, several technical details make this peridot appealing to the educated buyer. At 2.74 carat it sits in a size class that is relatively rare for peridot, where most commercial material is smaller, so weight alone enhances its market interest. The cushion outline with mixed brilliant cutting gives an ideal compromise between brilliance and color saturation, and the actual cut proportions produce a depth that promotes effective light return, approximately sixty four percent relative to the average diameter, a practical proportion for this shape that balances fire, scintillation, and face up spread. Slightly included clarity indicates the presence of small internal characteristics visible at eye level under close inspection, yet because the stone is clean in critical viewing angles and the polish is excellent, the inclusions have minimal impact on brilliance and do not detract from overall beauty. The fact that the gem has received no enhancement or heat treatment further supports its value, as untreated natural gems command premium interest among collectors and jewelers.

Provenance from Ceylon, Sri Lanka adds a layer of historic and market significance, as Sri Lankan peridot is known for its bright, pure green tones and reliable cutting material. For buyers who evaluate gems on a combination of optical performance, origin, and treatment status, this piece presents a compelling package. Practical considerations include the gem material hardness in the mid range, meaning careful setting is advised to protect faceted edges and to avoid prolonged exposure to harsh chemicals or extreme heat, and routine care with warm soapy water and a soft brush is recommended. For jewelry designers and collectors seeking a statement green stone with excellent polish, lively sparkle, and confirmed natural origin, this 2.74 carat cushion peridot from The Natural Gemstone Company represents an intelligent acquisition, offering both immediate aesthetic impact and enduring value based on its transparent, well cut, and untreated nature.
