0.90 Ct. Emerald from Zambia

This transparent Zambian emerald offered by The Natural Emerald Company weighs 0.90 carat and measures 8.01 by 6.16 by 2.74 millimeters, presented in a classic oval outline with a mixed brilliant faceting scheme. The gem displays a medium color intensity in a pure green hue, with color evenly distributed across the table and crown plane, providing a pleasing balance between tone and saturation. Clarity is graded included at eye level, which is typical for natural emeralds and results in visible internal features that contribute to the stone character without dramatically reducing its face up performance. The stone has undergone standard enhancement, which for emeralds is the established practice of clarity stabilization, and it has been finished to an excellent polish, yielding crisp facet junctions and a clean surface finish that accentuates both color and brilliance. Origin is Zambia, a source known for producing emeralds with stable green tones and relatively favorable clarity characteristics, and this provenance is reflected in the balance of hue and transparency seen in the specimen.

The mixed brilliant cut used on this oval is executed to optimize both light return and color saturation, combining a faceted crown with a partially brilliant pavilion to enhance scintillation while allowing the body color to remain expressive. The cutting geometry produces a shallow overall depth relative to the mean diameter, with a depth to mean diameter ratio of approximately thirty nine percent, which increases face up spread and makes the 0.90 carat weight appear larger when set. This geometry favors broad crown facets and a moderately sized table, generating even flash and minimizing windowing in the field of view. The cutter has prioritized symmetry and facet alignment, evident in the consistent facet sizes around the crown and the even distribution of pavilion facets that support stable light transmission. Excellent polish on all facet planes reduces microabrasions that can scatter light, and the finished girdle presents a consistent rim that facilitates precision setting. The mixed brilliant layout also helps to mask some internal mineral inclusions by breaking up large planes with multiple reflecting facets, which is especially effective in emeralds with included clarity grades.

From a durability perspective this Zambian emerald is well suited for daily wear when mounted with appropriate protective techniques and routine care, and the technical attributes of the piece support practical longevity. Beryl, the mineral family to which emerald belongs, has a Mohs hardness around seven and a half to eight, providing inherent resistance to casual abrasion, and the excellent surface polish further reduces the propensity for wear from repeated contact with softer materials. The included clarity grade indicates internal features that can affect toughness, however the standard enhancement stabilizes fissures and reduces the likelihood of fluid ingress or propagation of surface reaching fractures. The relatively shallow profile and strong facet junctions diminish the presence of acute pavilion angles that can act as stress concentrators, and this geometry lessens the risk of deep chipping under lateral impact. For daily wear applications we recommend protective mounting strategies such as full or partial bezel settings, low prong counts with reinforced heads, or halo frameworks that guard the girdle and crown facets from direct knocks. Routine care guidelines include avoidance of ultrasonic cleaning and steam, gentle cleaning with mild detergent and a soft brush, periodic inspection of the setting and reapplication of enhancement oil if indicated by a qualified lapidary. When set conscientiously and maintained according to these practices, this emerald combines the desirable aesthetic of a medium saturated green, the refined light performance of a mixed brilliant cut, and the stabilized integrity conferred by standard enhancement, making it a practical and attractive choice for everyday jewelry from The Natural Emerald Company.
