1.86 Ct. Emerald from Colombia - Muzo

This 1.86 carat, C.Dunaigre certified emerald presents a textbook emerald cut in a highly desirable green hue, and it is offered by The Natural Emerald Company. The stone measures 9.61 by 6.22 by 3.96 mm, yielding a depth that is approximately 50 percent of the average of length and width, a proportion that contributes to an elegant face up presence without sacrificing depth of color. The cutting is executed in the classic step cut language, with a broad, flat table and parallel pavilion and crown facets that create strong color windows and controlled light return. The polish is excellent, surface integrity is clean, and the symmetry of the facet junctions is precise, so the stone reads crisply in both direct and diffused lighting. Enhancement is standard, consistent with expectations for fine Colombian emeralds, and the origin is Colombia, Muzo, which is reflected in the vivid color intensity documented on the certificate.

From a faceting perspective this emerald embodies the functional geometry that collectors and jewelers seek in a step cut. The truncated corners and rectangular outline maximize durability and ease of setting, while the large table plane and successive, narrow tiers of crown and pavilion steps produce a calm, broad flash pattern rather than a scintillating brilliance. The cutter has respected the natural zonation of the crystal, orienting the pavilion steps to minimize light leakage along the long axis, and preserving material so that the stone exhibits generous color saturation across the entire table. The 9.61 mm length combined with the 6.22 mm width produces a pleasing rectangular elongation that photographs and sets well, offering a stable platform for either a bespoke ring setting or a collector mounting, especially for those who prefer precise, architectural cuts over brilliant cuts.

Color characteristics are central to the appeal of this gem, and this piece displays a vivid green with a slightly bluish secondary component that is typical of high quality Muzo material. The intensity is vivid, the tone falls in the medium to medium strong range, and the saturation is even, so the stone reads as a pure, lively green in a variety of lighting conditions. There is minimal directional color zoning, the result of careful orientation during cutting, and the step facets enhance the perception of depth by creating layered color planes rather than dispersed flashes. The vivid color intensity is particularly effective at the table, while the step facets on the pavilion create bands of deeper green when viewed at oblique angles, a effect that is prized by connoisseurs because it gives the stone a sense of internal volume and life. Excellent polish ensures that the surface transmits light unimpeded, allowing the internal color and character to be the primary visual story.

The inclusion suite in this emerald gives it an unmistakable signature that speaks directly to its Colombian provenance and its natural formation history. Internally there are fine three phase pockets and oriented tubular inclusions, along with narrow, healed fissures that have been treated with standard enhancement. These three phase inclusions, composed of liquid, a small gas bubble, and often a daughter crystal, produce tiny bright pinpoints when backlit, and they create an internal topography that reads as a delicate garden rather than as a distraction. Growth related chevron planes and fine silica stringers are present, forming subtle parallel features that interact with the step facets to create soft banding. There are also minute crystalline platelets and isolated crystal fragments that act as reflective accents, contributing to the gemological fingerprint that an experienced loupe examiner associates with Muzo origin. At eye level the stone is graded as very slightly included, and to the naked eye it presents as transparently clean with a velvety depth created by the internal structure. These inclusions serve as both a provenance marker and as an aesthetic advantage, providing character and internal texture that distinguish this emerald from more homogenized, heavily treated stones. The Natural Emerald Company selects such specimens for their collectors and clients who value natural signatures and technical craft, and the C.Dunaigre certification accompanies this gem to verify the described attributes. For setting and care, a secure bezel or prong design that protects the girdle and corners is recommended, and routine precautions regarding heat and harsh solvents are advised due to the standard enhancement.
