1.77 Ct. Emerald from Zambia

This transparent 1.77 carat round emerald presents precise proportions and a focused design, dimensions 7.39 by 7.36 by 5.67 millimeters, faceted with a mixed brilliant cutting style, clarity graded included at eye level, color intensity evaluated as intense, polish graded excellent, enhancement listed as standard. The mixed brilliant execution pairs a faceted brilliant crown with a modified pavilion, a strategy that concentrates light return into the table while preserving weight in the lower girdle. The stone exhibits a notably deep overall profile, with depth measuring approximately 76.9 percent of the mean diameter, a proportion that increases face up saturation and contributes to the stone appearing darker and more concentrated in tone when compared to shallower rounds. The round outline is nearly perfectly concentric, which together with crisp facet junctions and excellent polish maximizes scintillation of the crown facets and provides a lively contrast against the internal texture typical of natural emeralds.

From a gemological and visual standpoint this emerald demonstrates characteristics prized by advanced buyers who favor saturation over absolute windowing. The intense green is carried through the pavilion by controlled facet architecture that directs light through internal features rather than exclusively around them, producing a deep, velvety face up appearance. Inclusions are present and visible to the unaided eye, manifesting as a classic jardin of tiny early formed fissures and feathered inclusions. These internal features modulate brilliance by scattering light within the body of the gem, which in turn enhances perceived depth of color. Standard enhancement has been applied, a common practice in natural emeralds, with the purpose of minimizing the visual impact of fissures and improving apparent transparency. The excellent polish ensures that despite the included clarity grade, the surface condition does not detract from optical performance, and the mixed brilliant layout preserves lively crown flash while maintaining the stone's natural character and integrity.

When comparing hue and tone to emeralds from other famous localities, this Zambian example leans toward a cooler, bluish green with a heavier tonal weight. Colombian emeralds of high quality often display a slightly warmer or more pure green hue with a brighter, clearer face up appearance and a somewhat lighter tone when cut for optimal brilliance, which results in a different balance between dispersion and saturation. Brazilian material frequently shifts toward a yellowish green and can be lighter in tone and cleaner, which emphasizes vibrancy over the forest green depth seen here. Emeralds from Pakistan and Afghanistan may approach similar saturation levels, but they often retain a more neutral to slightly bluish cast and can present different inclusion signatures and transparency conditions. In practical terms this Zambian stone reads as more deeply saturated than typical Brazilian material, cooler and bluer than many Colombian pieces that emphasize clarity and lighter tone, and comparable in intensity to some Himalayan stones that are cut to emphasize color rather than windowing.

Collectors and connoisseurs will appreciate how the cut and proportions of this emerald work in concert with its origin and treatment to produce a distinct appearance that is immediately identifiable in hand. The mixed brilliant faceting and substantial depth enhance body color to deliver a dramatic face up presence, while the included clarity conveys natural origin and the typical jardin expected in emeralds. For clients seeking a dense, intensely colored green with a bluish bias and strong presence suitable for a solitaire or a bold jeweled centerpiece, this 1.77 carat round Zambian emerald is an exemplary candidate.
