1.64 Ct. Emerald from Zambia

This listing from The Natural Emerald Company describes one transparent, round shape, green emerald, weighing 1.64 carat, with dimensions of 7.61 by 7.60 by 4.91 mm, cut to a mixed brilliant style, clarity grade slightly included when evaluated at eye level, vivid color intensity, excellent polish, enhancement standard, and originating from Zambia. The measured profile yields a depth to diameter ratio of approximately 64.6 percent, a proportion that balances optical saturation with effective light return. The round outline has been executed with careful attention to symmetry, producing near identical girdle dimensions and a consistent pavilion profile, which is essential for even light distribution across the crown and pavilion facets. This piece presents the clear attributes that connoisseurs seek, transparent body color, a lively green that reads as vivid in both daylight and controlled lighting, and a faceting blueprint that maximizes the gemological strengths of Zambian emerald material.

The mixed brilliant cut of this emerald unites a faceted brilliant crown with a more restrained pavilion architecture, combining small star and kite facets above the girdle with step influenced pavilion facets below, thereby marrying scintillation with controlled color depth. The crown has been proportioned to allow adequate table presence while preserving strong crown facet angles, which enhance brilliancy without sacrificing body color. The pavilion depth and angles have been calibrated to the stone diameter and the material refractive index, promoting internal reflection and preventing excessive leakage of light through the culet. Facet junctions are crisp and well aligned, reflecting the excellent polish grade, and the girdle has been finished to a medium profile to facilitate secure mounting while minimizing potential stress concentrations during setting. These cutting choices are purposefully executed to accentuate the emeralds natural color and to mitigate the visual impact of internal features, so the observer perceives both depth of hue and lively facet patterning.

Color and clarity characteristics are central to this stones appeal. The vivid color intensity is evenly distributed across the table and crown facets, exhibiting a saturated green that is characteristic of Zambian emeralds, attributable to chromium and vanadium trace element chemistry in the host beryl. The tone sits in a range that reads as rich and verdant, without drifting toward excessive darkness, enabling the stone to display both internal color saturation and dynamic surface scintillation. Clarity is described as slightly included at eye level, a typical condition for natural emeralds, where internal features may be visible under direct inspection but do not substantially detract from the overall gem aesthetic. These internal features are natural growth related elements such as fine fissures and mineral inclusions, which also serve as internal fingerprints confirming natural origin, and they have been managed with standard enhancement to optimize transparency. The standard enhancement improves light transmission while remaining consistent with trade practice, and combined with the excellent polish, the stone presents a lively, transparent appearance that will attract close viewing and admiration.

This emeralds construction and finishing support longevity and enduring visual impact when set and worn with appropriate care. The combination of a robust mixed brilliant faceting plan, medium girdle, and excellent polish means the stone will continue to return light and hold its vivid hue over years of wear, provided standard emerald care is observed. We recommend protective mounting options for daily use, such as low bezel settings or secure prong settings with a protective collar, to reduce the risk of impact to the girdle and crown. Avoid mechanical cleaning methods such as ultrasonic baths and aggressive steam cleaning, and instead use gentle warm soapy water and soft brushes for routine maintenance, and seek professional inspection for any potential surface treatment maintenance, as standard enhancement may be refreshed by a trained lapidary if ever required. As with all fine colored gemstones, periodic professional checkups will preserve polish and structural integrity, and the natural color and brilliance of this Zambian emerald will continue to captivate for generations. This gem is offered by The Natural Emerald Company, supplied with provenance information and professional handling guidance, and represents a carefully cut and finished example of Zambian emerald material, suitable for collectors and jewelers who appreciate technical excellence and natural character.
