0.93 Ct. Emerald from Afghanistan

This is a transparent cushion shape emerald weighing 0.93 carat, with exact dimensions of 8.30 x 5.89 x 3.22 millimeters, cut in a mixed brilliant style. The mixed brilliant faceting preserves the traditional cushion silhouette while introducing a brilliant facet pattern that increases scintillation and internal light return. The gem presents a vivid color intensity that reads as a saturated, pure green with a subtle cool undertone consistent with high quality Afghan material. Clarity is graded as very slightly included at eye level, meaning that inclusions are minimal and do not interrupt the overall transparency or visual impact when viewed without magnification. The polish is excellent, facet junctions are sharp and free of abrasion, and the stone has undergone standard enhancement consistent with trade practice for emeralds to stabilize surface reaching fissures and to improve apparent clarity. Origin is Afghanistan, a source known for producing rich green tones with a slightly bluish bias, and this specimen exemplifies that regional character.

From a cutting and light performance perspective, the mixed brilliant approach used on this cushion emerald is a deliberate technical choice to reconcile color saturation with lively optical performance. Mixed brilliant faceting typically uses a brilliant facet pattern on the crown to create multiple small reflective facets that break incoming light into scintillation, combined with a more classical pavilion arrangement to control return angles and minimize light leakage. The dimensions yield a length to width ratio of about one point four to one, which is an elegant elongated cushion proportion that concentrates color along the longer axis. The measured depth relative to the average diameter equates to about forty five percent depth, a proportion engineered to balance depth of color with optimal face up spread. Excellent polish ensures that each facet plane functions as intended, preserving contrast and maximizing the stone surface reflectivity. In practical terms this means that under directional lighting the gem will exhibit crisp flashes of light across the crown facets while maintaining deep, saturated color when viewed face up.

When comparing brilliance to more common gemstones, it is important to separate brightness and scintillation from color intensity and optical depth. Emeralds, as a member of the beryl family, have a refractive index in the range of 1.565 to 1.602, and a low dispersion value around 0.014, both of which result in lower fire and flamboyant sparkle compared to diamond, whose refractive index is 2.417 and dispersion about 0.044. Corundum species, sapphire and ruby, have higher refractive indices than emerald, in the range of 1.762 to 1.770, and typically deliver more pronounced brilliance in equivalent cuts. What this emerald lacks in diamond like fire it more than compensates for in color depth and chroma. The mixed brilliant cut has been executed to maximize scintillation within the limitations of beryl optics, producing lively flashes and contrast that read brighter to the eye than many step cut emeralds or poorly cut cabochons. Compared to green tourmaline or peridot, which can exhibit higher birefringence and different light behavior, this Afghan emerald stands out due to its vivid saturation and superior transparency, which combine to create a visceral, saturated green that commands attention rather than relying solely on surface sparkle.

From a gemological and practical ownership perspective, the combination of vivid color intensity, transparent body, very slightly included clarity at eye level, and excellent polish makes this piece exceptional relative to typical market offerings. The standard enhancement performed is industry standard for emeralds and improves the appearance and durability without materially altering the underlying gem character, however care is recommended to avoid prolonged exposure to chemicals and to avoid ultrasonic cleaning. The Mohs hardness of beryl places emeralds in the seven point five to eight range, and because natural inclusions can introduce stress points, protective settings such as a bezel or lower profile prong work well for frequent wear, while open prong settings maximize light entry for jewelry where optical performance is the priority. The Natural Emerald Company stands behind the craftsmanship and origin disclosure for this piece and can provide detailed imagery under multiple lighting conditions, and, when requested, certified documentation. For collectors and designers seeking a green gem that combines the depth and authenticity of Afghan emerald material with a cutting strategy that enhances scintillation and face up brightness, this cushion mixed brilliant emerald is an outstanding choice.
