1.73 Ct. Emerald from Colombia

This listing presents a C. Dunaigre certificated emerald, weighing 1.73 carats, configured in a classic emerald cut, with precise dimensions of 8.37 by 7.19 by 4.53 millimeters, and an overall depth of approximately 58.2 percent. The gem is transparent, with an intense green hue and an excellent polish assigned after detailed inspection. Clarity is graded as slightly included when evaluated at eye level, a common and expected characteristic for fine natural emerald material, and the stone carries standard enhancement treatment typical of Colombian emeralds. Origin is Colombia, a region renowned for producing stones with strong saturation and a balanced bluish to pure green tone. The Natural Emerald Company offers this stone with full disclosure of its certification and treatments, enabling connoisseurs and trade professionals to assess both aesthetic and technical attributes with confidence.

The faceting architecture of this emerald is engineered to maximize controlled light play, leveraging the classical rectangular step cut geometry to emphasize color and broad flash return. The crown features a series of linear step facets that descend toward a substantial table plane, while the pavilion mirrors this arrangement with concentric rectangular steps terminating near a well proportioned pavilion depth. These parallel facet planes create a hall of mirrors effect, producing large directional flashes and face up brilliance that are more about color modulation than diamond like scintillation. The elongated facet geometry and crisp facet junctions channel internal reflection, reducing light leakage through optimized pavilion angles and maintaining saturation of the intense green when viewed face up. The beveled or truncated corners typical of the emerald cut serve a dual function, preserving the clean rectangular outline and mitigating the risk of cleavage along the beryl basal planes, which is particularly desirable for wearable settings.

Clarity characteristics in this specimen are documented as slightly included at eye level, and they interact with the geometric faceting to produce desirable optical texture rather than detract from visual appeal. Inclusions are oriented and distributed such that broad facet planes disperse and integrate these internal features, yielding attractive internal patterning under magnification and minimal disruption to the gem face up. The standard enhancement reported is consistent with acceptable industry practice, and it serves to stabilize surface reaching fissures without altering the inherent color chemistry derived from chromium and vanadium trace elements typical of Colombian material. Excellent polish is evident on each facet plane, with smooth facet surfaces and crisp facet intersections that permit unobstructed transmission and reflection of light, ensuring that the step facets perform to their full potential. Girdle thickness is even, and table centering is precise, contributing to predictable optical behavior and facilitating accurate mounting considerations.

From a craftsmanship and placing perspective, this 1.73 carat emerald cut is well suited to settings that prioritize color saturation and elegant geometry, including solitaire rings with minimal bezel intrusion, three stone configurations with tapered side stones, and refined pendants that allow an open table presentation. The proportions of 8.37 by 7.19 by 4.53 millimeters yield a visually substantial face up area relative to weight, enhancing presence while maintaining comfortable wearability. The cut quality, confirmed by C. Dunaigre certification, shows professional lapidary control over facet alignment and pavilion depth, producing a balanced relationship between light return and color intensity that collectors and jewelry designers value. The Natural Emerald Company stands behind the provenance and documentation of this gem, and we welcome requests for additional high resolution imagery, mounting recommendations, and viewing appointments for buyers who require hands on evaluation.
