1.38 Ct. Cabochon Emerald from Afghanistan

One beautiful translucent 1.38 carat cushion shape green emerald is presented by The Natural Emerald Company, with precise dimensions of 8.16 x 6.19 x 3.69 mm. The gem features a traditional sugar loaf cut that emphasizes its depth of color, and it carries a clarity grade of slightly included as evaluated at eye level. Color is classified as intense, and the finish is an excellent polish that enhances face up saturation and surface luster. Enhancement is reported as standard, reflecting the accepted practice of minor oiling or resin filling to stabilize and improve the apparent clarity, and the emerald is traced to Afghanistan, a provenance known for producing deeply hued stones with attractive character. For the educated buyer, these combined attributes deliver a balance between visual impact and market recognition, backed by consistent grading language and transparent disclosure from The Natural Emerald Company.

The optical behavior and internal structure of this emerald are what give it a sparkle that is so distinctive. As a member of the beryl family, with the characteristic Be3Al2Si6O18 framework and a hexagonal crystal habit, emeralds refract and transmit light in ways that create depth and lively scintillation. Typical refractive indices near 1.577 to 1.583 and a modest birefringence around 0.005 to 0.006 mean that light entering the stone is finely split and redirected, producing subtle flashes of brightness and color when the gem is tilted. Pleochroism, the display of different greens and bluish greens from different angles, adds to perceived movement, and the sugar loaf cutting style enhances internal reflections by curving the pavilion to trap and return rich green tones to the viewer. The slightly included clarity grade is consistent with natural emerald formation, where microscopic fissures serve to catch light and contribute to a lively internal texture rather than detract from beauty. Excellent polish on the facets ensures maximum light return and surface brilliance, so the gem reads with striking presence in jewelry. At The Natural Emerald Company we emphasize provenance, accurate grading, and honest enhancement disclosure, so discerning buyers can appreciate both the scientific reasons for this emeralds exceptional sparkle and its lasting desirability.
