1.52 Ct. Emerald from Zambia

This outstanding transparent emerald offered by The Natural Emerald Company is a precisely executed 1.52 carat specimen, presented in a classical emerald cut, with exact dimensions of 8.07 by 6.16 by 4.21 millimeters. The faceting style is a step cut, characterized by parallel crown and pavilion facets which form concentric rectangular steps that emphasize color and clarity rather than scintillation. The length to width ratio sits near 1.31, which yields a balanced rectangular profile that reads elegantly both mounted and loose, and the depth percentage is approximately 59 percent, a proportion that supports optimal light return for this cutting style. The table is generous enough to present a broad field of green, while the controlled step faceting limits windowing and preserves color saturation throughout the stone, demonstrating disciplined material planning by the cutter.

The clarity grade is very very slightly included, as evaluated at eye level, a notable attribute for a natural emerald from Zambia, since beryl often contains jardin features. Under loupe inspection the inclusions are minute and strategically positioned so as not to interrupt the visual flow of color, thereby maintaining transparency and brilliance across the table and steps. The excellent polish across all facets produces crisp facet junctions and smooth facet planes, which enhances facet contrast and allows the stone to deliver clean, saturated flashes of green under varied lighting. Enhancement is standard, reflecting responsible, minimal oiling or resin filler treatments commonly employed to improve surface reaching fissures, these treatments are stable and reversible under the appropriate professional care.

Color is vivid in intensity, presenting a rich, medium to medium dark tone with strong saturation that is emblematic of high quality Zambian material, where chromium and vanadium balance yields a slightly bluish to pure green spectrum. The hue is evenly distributed, with no perceptible color zoning, allowing the step cut to present a uniform color field rather than patches of light or dark, and the precision of the cutting geometry ensures that each step facet works to deepen the perceived color rather than dissipate it. Craftsmanship details include symmetrical beveled corners, well aligned step facets, and proportionate crown and pavilion angles, these elements combine to deliver stable color performance and minimize light leakage. The girdle has been finished to a consistent thickness to facilitate secure mounting without creating stress points, and the culet is proportioned to maintain pavilion symmetry.

On the Mohs scale this emerald ranges at approximately 7.5 to 8, which positions it above quartz and most common silicates, yet below the corundum family and far below diamond, therefore it offers good resistance to everyday abrasion while requiring mindful handling due to natural brittleness and internal stresses from inclusions. Compared to diamond at ten and sapphire at nine, this emerald is softer and less tough, due to cleavage tendencies inherent in beryl crystalline structure, so protective settings such as a bezel, halo, or four corner prongs are recommended to reduce the risk of edge chipping. Ultrasonic cleaning and steam exposure should be avoided for standard enhanced emeralds, instead warm soapy water and a soft brush are the safest cleaning methods, and routine professional inspections of the setting are advised to preserve both the stone and the treatment stability. For clients who require secure everyday wear, The Natural Emerald Company can advise on mounting options and matching accent stones, ensuring that this vivid Zambian emerald is both showcased and protected to industry leading standards.
