0.79 Ct. Yellowish Green Peridot from Pakistan

This 0.79 carat cushion shape peridot from Pakistan offered by The Natural Gemstone Company presents a technically refined example of the species, with exact dimensions of 6.00 by 4.81 by 3.31 mm, a mixed brilliant cut, a clarity grade evaluated as very slightly included at eye level, medium color intensity, and an excellent polish, with no enhancement. The cushion outline is slightly rectangular in proportion, which the cutter has used deliberately to balance table size and pavilion depth, creating a measured play between breakout of light and preservation of weight. The stone reads as yellowish green under neutral lighting, the hue leaning toward the warmer side of the peridot spectrum while retaining a clear green presence, and this color balance is a direct result of iron content in the olivine structure interacting with the specific facet arrangement selected for this piece. The lack of enhancement and the documented origin from Pakistan further underscore the natural character of the material and the expectation of stable color and durability under normal wear conditions.

The mixed brilliant cut of this piece is engineered to maximize scintillation and return in a gem with a refractive index in the mid 1.60s range, using a step influenced crown and a brilliant style pavilion to generate contrast. The cutter has maintained a depth of approximately 3.31 mm, which results in a depth ratio of about 61 percent relative to the mean of the length and width measurements, a proportion that yields a lively face up appearance without excessive windowing or dead zones. On the crown, truncated bezel facets and a restrained table give controlled light leakage and allow for selective color saturation across the table field, while the pavilion bears a series of triangular and kite shaped facets arranged to break the light into tight flashes, amplifying the medium saturation and contributing to the perception of clean, bright green. The girdle is consistent and slightly faceted, preserving security for setting and minimizing the risk of accidental cleavage, and the excellent polish across all facets enhances facet junction crispness and optical return.

What marks this peridot with an unmistakable signature are the internal features and how they interact with the cutting geometry to create a distinctive optical fingerprint. At eye level the stone is very slightly included, which translates to a predominantly clean face up appearance with a few discrete inclusions that become character defining under loupe and microscope. Notable are a constellation of minute reflective platelets and tiny crystal pinpoints aligned along a slightly oblique plane near the pavilion, a faint disk like stress feature resembling the classic peridot lily pad, and a handful of slender, low relief growth lines that run subparallel to the long axis. These inclusions are not detrimental to performance, rather they provide a multilayered internal topography that scatters light in microflashes and produces a subtle iridescent ringing at certain viewing angles. The optical interaction between these platelets and the pavilion facets generates micro scintillation that can be read as a signature pattern when the gem is rotated under spot lighting, and the distribution and morphology of these features are broadly consistent with peridot specimens from high elevation skarn and mantle xenolith related deposits in Pakistan.

For the technically minded buyer contemplating application and setting, this peridot performs predictably and elegantly, combining stable medium color intensity with a measured facet arrangement that favors brilliance and durability. The slightly rectangular cushion silhouette and the mixed brilliant architecture make the gem well suited to bezel or prong settings that allow light ingress to the pavilion while preserving the characteristic internal platelets that contribute to its identity. Because the stone is unenhanced and has excellent polish, it will respond well to routine jewelry maintenance and will retain its optical characteristics with normal care. The Natural Gemstone Company presents this peridot as a specimen that offers both gemological interest and practical application, appealing to collectors who value inclusion based provenance indicators as well as designers who require consistent face up appeal and secure setting proportions.
