0.47 Ct. Yellowish Green Peridot from Pakistan

This oval shaped peridot from Pakistan is a study in proportion and optical efficiency, precisely cut to 6.12 x 4.12 x 2.67 mm and weighing 0.47 carat. The length to width ratio is 1.48, placing it squarely within the classical oval range that balances face up presence with wearable elegance. The measured depth is 2.67 mm, which produces a depth percent of approximately 52 percent when calculated against the average diameter. This depth percentage is intentionally chosen to optimize light return in a mixed brilliant geometry, preventing a washed out face up appearance while maintaining an attractive pavilion depth for lively scintillation. The cutting style is faceted with a mixed brilliant arrangement, combining a brilliant facet pattern on the crown and a modified facet layout on the pavilion to create both broad flashes and pinpoint scintillation. The result is an oval that sits well in a variety of settings, from low profile bezels to four prong mounts, preserving table presence while maximizing brilliance.

Optical performance derives directly from the material properties of peridot and the precision of the faceting. Peridot has a refractive index in the range of approximately 1.65 to 1.69 and a birefringence on the order of 0.036 to 0.038, physical constants that favor strong internal reflection and crisp facet contrast when proportions are optimized. In this specimen the mixed brilliant cut leverages those properties by directing incoming light into repeated internal reflections across the pavilion facets before returning it through the brilliant crown. The excellent polish at facet junctions minimizes scatter and preserves integrity of specular reflections, so that each facet edge reads as a sharp highlight under direct illumination. Clarity is evaluated as very very slightly included at eye level, which in practical terms means the stone is eye clean and free of any inclusions that would interrupt major light paths, allowing unimpeded light transmission and a high degree of brilliance. Because there has been no enhancement to color or clarity, the intense yellowish green hue is wholly natural, produced by iron in the olivine crystal lattice and preserved by careful lapidary work.

Color dynamics and scintillation are where structure and cut converge to produce a sparkle that is difficult to replicate in other gem species. The intense yellowish green color displays both saturation and purity, and the mixed brilliant facet scheme creates contrasting zones of light and dark that enhance perceived depth and movement. As the stone is rotated, the crown facets offer broad flashes of color while the pavilion facets contribute rapid, lively scintillation. The minor birefringence of peridot can also impart a subtle doubling effect along facet edges when viewed with magnification, a characteristic that can enrich the visual complexity of the gem without detracting from clarity in this example. Fire, understood as spectral dispersion, is modest given peridot chemistry, so the visual impact relies predominantly on strong light return and high contrast between mirror like facets and darker windowed areas. The excellent polish and symmetrical oval outline ensure crisp facet junctions, clean table reflection, and a lively return of light even under lower intensity room lighting.

As a member of our curated inventory at The Natural Gemstone Company this peridot represents a thoughtful union of natural material quality and exacting lapidary technique. The combination of eye clean clarity, intense natural color, mixed brilliant faceting, optimal proportional depth near 52 percent, and an ideal length to width ratio produces a gemstone whose sparkle is both immediate and nuanced. For the connoisseur who values technical precision, this stone offers verifiable optical advantages rooted in refractive index, birefringence, and superior cutting practice, all presented in a stable, untreated peridot from Pakistan.
