0.77 Ct. Peridot from Burma (Myanmar)

This transparent 0.77 carat round peridot measures 5.87 by 5.97 by 3.50 millimeters and has been fashioned with a mixed brilliant cut that balances table size and pavilion depth to optimize light return. The gem displays a yellowish green hue with medium color intensity, and the surface has been finished to an excellent polish. Clarity is described as very slightly included when evaluated at eye level, indicating the presence of only minor inclusions that do not materially interfere with transparency or overall visual appeal under normal viewing conditions. This specimen has undergone a standard heat treatment to stabilize and refine its tone, and its origin is documented as Burma Myanmar. The Natural Gemstone Company presents this peridot as a single, well proportioned stone suitable for detailed settings where both color and facet precision are important.

Optically the stone exhibits the characteristic vitreous luster and brisk brilliance associated with quality peridot. The mixed brilliant cut promotes strong return of light from the crown and pavilion, producing crisp facet reflections and a lively face up appearance. Peridot is singly refractive with a noticeable birefringence that can produce subtle doubling of facet junctions when viewed through the table at certain angles. This birefringence contributes to a distinct internal sparkle that differs from the scintillation pattern of singly refractive gems with higher dispersion. The excellent polish on this piece enhances facet crispness and maximizes light transmission, while the medium color intensity allows for both internal facet contrast and external reflections that read as a clear yellow green under natural and controlled lighting.

When compared to other gems within the green category and to other peridots, the reflective qualities of this Burmese stone show specific strengths and natural limitations. Peridot typically has a refractive index in the range of approximately 1.65 to 1.69 and a modest dispersion, which yields lively brilliance without pronounced fire. Relative to green garnets such as tsavorite, which have higher refractive indices around approximately 1.74 to 1.76 and consequently greater brilliance and fire, this peridot will produce a cleaner, more glass like sparkle rather than the intense scintillation found in high RI garnets. Compared with beryl family stones such as emerald, which typically present at lower refractive indices near approximately 1.57 to 1.58 but often show heavy inclusions, this peridot offers a brighter, more reflective face up appearance because it combines clearer transparency with fewer inclusion interruptions. Against green tourmaline, whose refractive index falls in a range similar to peridot at approximately 1.62 to 1.64 but which commonly shows stronger pleochroism, the peridot delivers a more uniform color response and a steadier pattern of light return. Chrome diopside and some chrome rich stones can display deeper saturation and different reflective behavior due to higher dispersion and slightly different refractive properties, so this peridot reads as a more lively, lighter green that emphasizes facet brilliance over depth of color.

In practical terms this peridot is best appreciated in settings that allow light to enter and reflect through the pavilion, where the mixed brilliant cut and excellent polish will be most effective. The very slightly included clarity grade means the stone will present as clean to the casual observer, and the disclosed heat treatment is a stabilizing enhancement that is widely accepted in trade practice. The documented Burmese origin provides useful provenance information for those who weigh locality in acquisition decisions. The Natural Gemstone Company confirms these characteristics based on our standard evaluation, and we present this gem for clients seeking a refined peridot with clear optical performance, balanced color intensity, and cut geometry designed to deliver consistent, lively reflections.
