12.01 Ct. Cabochon Emerald from Colombia

This parcel presents a single, semi-translucent cushion shape emerald weighing 12.01 carat, with calibrated dimensions 14.20 x 15.47 x 7.90 millimeters, and an overall depth percentage of approximately 53.3 percent, parameters that confirm an efficient weight yield from the rough. The stone is executed in a traditional sugar loaf form, characterized by a high domed crown and gently sloping shoulders rather than a faceted pavilion, an approach that prioritizes color saturation and depth over facet-induced brilliance. Color grading reads as vivid, with a saturated medium to deep green that remains consistent across the table and crown curvature, and the semi-translucent body allows for a luminous internal glow while maintaining strong chroma. Origin is Colombian, which correlates with the stone’s bluish-green undertones and translucent clarity signature, and the finish is described as excellent polish, producing crisp specular highlights on the dome and clean reflective planes at the shoulder junctions.

Clarity is evaluated as very slightly included at eye level, a grade indicative of minor internal characteristics that do not materially detract from visual appeal when the stone is viewed face up. The inclusion suite is typical for Colombian emeralds, comprising minute pinpoint crystals and narrow feathering that sit primarily toward the pavilion slopes and girdle interface, with limited impact on the gem’s overall transparency and color rendition. Enhancement is standard, applied to minimize the visual effect of surface-reaching fissures, using conventional low refractive index oil filling practices to improve apparent clarity while leaving internal features visible under magnification. The sugar loaf treatment and the very slightly included clarity grade combine to yield a gem that displays broad, even color planes and a soft, velvety internal texture rather than pronounced facet scintillation, and the excellent polish preserves smooth facet transitions and a uniform surface sheen.

From a craftsmanship and setting perspective, the gem demonstrates careful lapidary control, with symmetrical cushion outlines, uniformly rounded corners, and well-balanced crown height that provide predictable optical behavior in a variety of mounting types. The domed sugar loaf top produces expansive color fields and controlled light return, making the piece especially well suited to bezel and closed-back settings that emphasize color depth, or to museum style mounts where the stone can be shown face up to display its saturated tone. Proportions are robust, with a girdle profile that supports secure setting without excessive material removal, and the stone’s semi-translucent nature offers designers options to either enhance backlighting for more luminous presentation or to retain an opaque, deep green table for classical elegance. The Natural Emerald Company offers this Colombian sugar loaf emerald with full disclosure of enhancement and origin, and with photographic and dimensional documentation to support appraisal and design planning, making it an attractive acquisition for connoisseurs who prioritize natural color, artisanal cutting choices, and traceable provenance.
