1.27 Ct. Emerald from Zambia

This specimen is a transparent, oval shape emerald, weighing 1.27 carats, with precise dimensions of 9.60 millimeters by 7.52 millimeters by 3.33 millimeters. The cutting style is faceted, executed in a mixed brilliant configuration that balances scintillation and color saturation. The total depth relative to the average diameter is approximately 38.9 percent, a proportion that preserves body color while allowing efficient light return across the crown. Clarity has been graded as slightly included when observed at eye level, which is typical for natural emeralds and imparts character without unduly compromising durability. Color intensity is rated as intense, producing a vivid green field that remains consistent across the table and pavilion facets. The polish is excellent, with facet junctions showing crisp, clean edges and mirror like facet planes that maximize contrast and sparkle. Enhancement is standard, applied to improve apparent clarity and stability in a manner consistent with trade practice, and the origin of this gem is Zambia, which materially influences its gemmological profile and market value.

The mixed brilliant cut deployed on this oval has been planned to marry brilliant style crown faceting with pavilion faceting that returns light in a manner that deepens the green saturation. The crown exhibits well proportioned facet angles that create strong dispersion in white light while maintaining dominance of the green chroma. The pavilion geometry has been tuned to the stone s specific depth and refractive properties to minimize light leakage through the sides, thereby preserving the intense face up color. Facet symmetry is uniform around the oval outline producing a balanced flash pattern when rotated. Because the stone is slightly included at the eye level, the cutter s choice to use a mixed brilliant scheme is particularly effective, since the brilliance helps to visually blend minor inclusions while the controlled pavilion depth concentrates color in the viewing plane. The result is an emerald that reads as intense and vivid when mounted, but that retains the natural internal features that confirm its identity and provenance.

Clarity wise, the emerald presents typical natural inclusions, consisting of fine needles and pinpoint crystals that are distributed within the crystal lattice. These internal characteristics are consistent with a clarity grade of slightly included at the unaided eye level, and they do not compromise the structural integrity of the gem in normal wear. The standard enhancement observed is consistent with industry practice for emeralds and is intended to stabilize surface reaching fissures and to improve apparent transparency. Because such enhancements are routine, it is important to follow recommended care protocols, as the filling medium can be affected by strong solvents, prolonged exposure to heat, and ultrasonic vibration. We advise against steam cleaning and suggest warm water, a mild detergent, and a soft brush for routine maintenance. Periodic inspection by a qualified technician is advisable if the stone will be set in jewelry that undergoes frequent wear, and re application of filler may be performed if necessary to maintain optical performance. For mounting, protective settings that reduce edge and table exposure, such as a bezel or a secure prong design with a protective halo, will extend the longevity of the stone and preserve the integrity of any enhancement.

The Zambian origin imparts distinct and quantifiable value to this piece, and this is a point of emphasis in valuation and provenance. Zambian emeralds, most prominently those from the central African deposits, are prized for their deep, bluish green saturation and their high color intensity at sizes comparable to this 1.27 carat stone. The trace element chemistry of Zambian emeralds typically includes contributions from chromium and vanadium that drive the saturated tone, and the local geological formation yields crystals with a transparency and hue profile that collectors and connoisseurs specifically seek. Provenance enhances market desirability because buyers value predictable color profiles and established supply histories, and because documented origin supports long term collectibility and resale. At The Natural Emerald Company we provide detailed descriptions of cutting, clarity, and enhancement, and we can assist with independent laboratory verification of origin and treatment upon request. We also offer bespoke setting consultation to optimize optical performance and to protect the stone s filled features, and we welcome enquiries from jewelers and collectors who require exacting specifications and traceable provenance.
