1.90 Ct. Emerald from Zambia

One beautiful transparent 1.90 carat pear shape green emerald with dimensions 10.19 x 6.93 x 4.46 mm is presented by The Natural Emerald Company, the proportions and finishing of this stone reflect deliberate lapidary control, the length to width ratio of approximately 1.47 produces a pleasing pear silhouette that balances elegance with visual presence, the 4.46 mm depth gives the pavilion sufficient volume to concentrate color while preserving lively return, the mixed brilliant cut employed combines a precisely faceted brilliant crown with a carefully calibrated pavilion that bridges step style geometry and brilliant style reflectors, the result is a gem whose silhouette reads both modern and classical, the clarity grade is slightly included under loupe and evaluated at eye level, inclusions are typical of natural Zambian emeralds and are oriented so that they do not dominate the face up appearance, the color intensity is categorized as intense, a rich medium to deep green with vivid saturation and balanced tone, enhancement is standard, consistent with accepted practice for natural emeralds, and polish is excellent, the facet junctions are sharp and the girdle finish is consistent with high level trade standards.

The mixed brilliant faceting architecture on this pear shape has been optimized to marry scintillation with color saturation, the crown features a series of kite and triangular facets arranged to produce a dispersed return of white light and colored flashes when the gem is moved, the pavilion incorporates modified brilliant facets that act to recycle light back through the crown while preserving the depth of color in the body of the stone, this hybrid approach reduces the risk of excessive light leakage that can wash out color, and it minimizes the visibility of internal feathering under common viewing positions, the gem displays modest pleochroism typical of emerald from Zambia, shifting subtly between pure green and slightly bluish green as it is rotated about its axis, the optical properties of beryl mean the refractive index band near 1.577 to 1.583 supports a soft but persistent brilliance, the slightly included clarity grade plays a role in the gem character, certain inclusions create delicate internal reflections and a three dimensional depth that can enhance the visual complexity rather than detract, craftsmanship is evident in the symmetry of the pear point and the balanced distribution of facet sizes, the table is proportioned to provide a strong window for observing the intense green while the facets immediately surrounding it contribute to lively scintillation.

Under a range of lighting conditions this emerald will communicate its character in nuanced ways, in bright daylight and cool northern light the intense green will appear at its most saturated and pure, the stone will show deep verdant tones with crisp internal contrast, the mixed brilliant crown will disperse daylight into lively white scintillation that offsets the green body color, in direct sunlight the emerald will produce flashes of bright white brilliance from the facet edges while the core color will deepen to a richer green, direct beams will emphasize internal reflections and can reveal subtle bluish pleochroic components, under warm incandescent lighting the stone will take on a slightly warmer appearance, the green will read as more botanical and slightly softened, scintillation will become creamier and the contrast between flashes and body color will be less stark, under LED illumination with high color rendering the emerald will respond similarly to daylight, the intense saturation will remain true and the polished facets will send out bright crisp flashes, in halogen spot or pendant settings a concentrated beam delivers pronounced pinpoint scintillation and a strong visual pop, this effect makes the stone ideal as a center in a ring or a pendant where movement and light interaction are frequent.

Lighting is not the only determinant of perceived beauty, mounting choices and surrounding materials will modulate the visual outcome, warmer metals such as 18 karat yellow gold will enhance the richness of the green and can visually increase perceived saturation, cooler metals such as platinum or white gold will make the stone appear marginally crisper and lean into the bluish components of its pleochroism, a halo of small diamonds or white gemstones will increase apparent brightness by providing contrasting white sparkle that frames the emerald, a bezel setting will protect the slightly included stone and its standard enhancement, while prongs will allow maximum light entry and movement, because the enhancement is standard it is advisable to avoid aggressive steam cleaning and harsh chemicals, routine cleaning with mild soap and water and a soft brush will maintain the excellent polish and surface luster, The Natural Emerald Company offers this 1.90 carat Zambian pear as a technically refined example of mixed brilliant cutting and traditional emerald character, it will suit collectors and connoisseurs who appreciate deliberate facet planning, measured proportions, and a vivid, intense color that evolves gracefully under varied light.
