3.96 Ct. Green (Lime Green) Peridot from Pakistan

This specimen from The Natural Gemstone Company is a transparent lime green peridot, weighing 3.96 carats, and presented in a classic cushion outline. The calibrated dimensions measure nine point zero one by eight point nine three by six point nine four millimeters, producing a depth that registers at approximately seventy seven percent relative to the average of the length and width. The gem exhibits an intense color intensity, coupled with a clarity grade of slightly included when evaluated at eye level, an excellent polish, and a declaration of no enhancement. The material is sourced from Pakistan, a locality known for producing peridot with lively grass and lime tones, and the overall presentation emphasizes both the aesthetic saturation and the technical execution of the cutting and finishing processes.

The cut is a mixed brilliant style, specifically configured to exploit the refractive and optical properties intrinsic to olivine group minerals. Peridot has an approximate refractive index range from one point sixty five to one point sixty nine with measurable birefringence, and a mixed brilliant approach leverages these parameters by combining a brilliant facet array on the crown with a controlled, modified pavilion faceting below. The brilliant crown facets are cut to precise relationships that promote strong return of incident light as white flashes and high contrast scintillation, while the pavilion uses a sequence of broader, planar facets that generate larger internal reflections and reinforce the stone s color saturation. This hybrid arrangement reduces light leakage through the pavilion by redirecting rays back through the table and crown, creating a balance between lively sparkle and sustained, even color. The relatively deep pavilion profile of this piece contributes to a pronounced windowing of color, so that the lime green reads intensely from multiple viewing angles rather than fragmenting into small, high frequency flashes.

Facet planning and facet junction control are critical with peridot because the material s moderate birefringence can cause doubling or softening of facet lines if misaligned with the optic axis. In this example the cutter oriented the pavilion and crown arrays to minimize interference with the optic axis, maintaining tight facet junctions and consistent facet symmetry. The result is a mixed brilliant execution where the crown s star and bezel facets act as primary generators of scintillation, and the pavilion s extended facets act as secondary playfields that deepen tonality and preserve saturation. The table size has been selected to mediate between impulse brightness and color depth, allowing strong reflections without opening a large color window that would dilute the intense green. The excellent polish enhances the surface transmission of light and preserves crisp facet demarcation, which in turn sharpens the contrast between bright flashes and dark reflective zones, increasing perceived brilliance without relying on dispersion or fire.

Clarity characteristics are described as slightly included at eye level, a practical grade for peridot of this weight and color intensity. The internal features are limited in scale and strategically positioned so they do not interrupt the main light paths through the stone. Because the mixed brilliant design concentrates return light through coordinated facet planes, minor inclusions that sit outside those planes have minimal impact on overall brightness. From a craftsmanship standpoint the gem was preformed to retain maximum rough yield while prioritizing color zoning that favored the dominant lime green hue, and subsequent faceting was executed with tool control that preserved facet symmetry and maintained optical alignment. No heating or other enhancement has been applied, so the original pleochroic tendencies and intrinsic absorption characteristics remain intact, providing an authentic representation of the Pakistani material.

For the technical buyer who values measurable tradeoffs between color, clarity and optical performance, this cushion mixed brilliant peridot offers an instructive case study. The combination of an intense lime green bodycolor, a mixed faceting scheme that optimizes both scintillation and color saturation, and a deep pavilion proportion creates a gemstone that reads as lively and saturated in a jewelry setting, especially in rings or pendants where light return from varied angles is advantageous. The depth percentage near seventy seven percent produces a noticeable visual depth that sets this stone apart from flatter equivalents, and the excellent polish ensures that the face up presentation remains crisp and luminous. The Natural Gemstone Company stands behind the origin and treatment statement, and we are prepared to provide additional measurements or high resolution imaging for close inspection upon request, ensuring that discerning clients receive the technical documentation they require to evaluate this peridot for both aesthetic and gemological suitability.
