2.17 Ct. Emerald from Colombia

This C.Dunaigre certified 2.17 carat asscher octagon green emerald from Colombia exemplifies precision gemmological standards and refined lapidary execution. Dimensions are 7.86 by 7.35 by 5.32 millimeters, an ideal platform for an asscher faceting scheme, and the stone carries a vivid color intensity with a clarity grade recorded as slightly included at eye level. Enhancement is standard, consistent with responsible trade practice, and the piece is offered through The Natural Emerald Company with full certification from C.Dunaigre. The asscher octagon silhouette presents near square proportions with truncated corners, creating a compact face up that accentuates color saturation and lends architectural presence. Weight distribution and pavilion depth have been optimized to balance color concentration with light return, the result of deliberate proportioning that preserves both the emeralds intrinsic hue and its three dimensional depth.

The asscher cut faceting structure on this specimen relies on stepped facets arranged in concentric tiers, producing the classical hall of mirrors effect while maintaining controlled flashes of light rather than broad scintillation. Facet junctions display crisp symmetry and consistent angulation, attributes that are immediately evident under loupe examination and during normal wear. Excellent polish enhances facet transparency and edge definition, minimizing surface diffusion and allowing internal color zoning to read true and uninterrupted. The cutter oriented the pavilion and crown facets to manage internal stress lines and to place minor inclusions in less conspicuous facet intersections, a common and highly skilled technique in fine emerald cutting. This level of lapidary care, combined with careful table sizing and crown height selection, yields uniform light passage through the body of the gem, ensuring even color distribution from table to girdle and from crown to culet.

Color, clarity, and enhancement interact in a way that elevates the apparent purity and depth of tone. The vivid intensity of the green, characteristic of high grade Colombian material, is achieved through an even balance of hue and saturation, the stone presenting a rich medium to medium dark tone that reads well under both daylight and reefed light sources. Slight inclusions, evaluated at eye level, are consistent with natural emerald formation and are managed rather than concealed, allowing the gem to retain authenticity while offering visual cleanliness. Standard enhancement has been applied to improve apparent clarity and surface smoothness, a practice that stabilizes the stone and reduces the visual impact of minor fissures without altering the intrinsic color parameters. From a gemmological perspective, this interplay produces an optic that is deep and lively, where the step faceting confines color to planes that reveal internal structure and generate depth, and the excellent polish ensures that those planes remain transparent and brilliant when viewed from multiple angles.

As a center stone, this asscher octagon emerald lends itself to precision settings that respect its geometry and optical behavior, such as bezel variants with open galleries or four prong settings that allow light ingress to the pavilion. The compact profile and calibrated measurements permit tight mounting tolerances, enabling jewelers to create secure, elegant settings that do not compromise light performance. For clients who demand technical excellence, The Natural Emerald Company provides full access to the C.Dunaigre report, and we can supply high magnification imaging and facet maps on request to support design and appraisal work. Practical care recommendations include avoiding steam and ultrasonic cleaning because of the standard enhancement, and relying on gentle warm soapy water and a soft brush for routine maintenance, periodic professional inspection will ensure the integrity of both the stone and its setting. The flawless execution of cut and polish on this vivid Colombian asscher, combined with its responsible enhancement and certified provenance, produces a gem whose formal precision and optical depth enhance its beauty from every angle.
