0.52 Ct. Emerald from Brazil

This transparent 0.52 carat trillion shape green emerald measures 5.76 by 6.11 by 3.46 millimeters, with a faceted cutting style executed in a modified brilliant triangular form. The cutter has preserved a balanced face up spread by maintaining a depth near sixty percent, which maximizes the pavilion refraction and produces an even light return across the three facets. The table is proportioned to create crisp windowing control and the crown facets are faceted shallow enough to increase apparent color saturation without causing excessive extinction. Clarity is graded as slightly included at eye level, which is consistent with natural internal garden features and minor fissures commonly seen in emeralds, and enhancement is disclosed as standard, applied to stabilize and improve apparent clarity while preserving the natural identity of the stone. Polish is excellent, yielding sharp facet junctions and minimal surface abrasion, so the stone presents as lively and clean when viewed through a loupe or with the naked eye.

Optically the stone exhibits vivid color intensity, with a hue that reads as a pure green with a slight blue bias under neutral daylight, shifting subtly to a fresher grass green under incandescent and warm LED sources due to emerald pleochroism. When compared to classic Colombian emeralds from Muzo and Chivor, which are often characterized by a deep, velvety bluish green and a slightly darker tone, this Brazilian specimen is relatively more vivid on the face up view and carries a livelier, more transparent clarity that favors brilliance over the oilier depth associated with some Colombian stones. Compared to Zambian emeralds, which often sit one step darker with a denser bluish green tone and greater visual heft, this emerald reads brighter and cleaner, with more light modulation through the triangular facets. Compared to historical Russian and Egyptian material which can lean toward yellowish green, the present stone maintains a cooler green axis, making it versatile for both classic and contemporary settings.

From a cutter and setter perspective the trillion faceting was chosen to emphasize the stone body color while producing strong fire and scintillation for its size. The trifaceted symmetry and balanced girdle allow for predictable light behavior, so the pavilion angles produce internal reflections that return vivid color to the eye instead of losing tone to deep extinction. The slight inclusions are typical growth features, including faint three dimensional veils and pinpoints, which after standard enhancement render as soft nebulous areas rather than stark dead zones. This means the gem retains integrity for everyday wear when set with protective prongs or a partial bezel to safeguard the pointed corners. Given the dimensions and weight, the emerald is ideal as a distinctive center for a minimalist ring or as a striking accent in bespoke ear pieces, and it pairs particularly well with warm yellow gold to amplify the green warmth, with platinum or white gold to emphasize the cooler bluish nuances.

Provenance is an important component of our valuation and presentation, and this Brazilian origin piece offered by The Natural Emerald Company displays the hallmarks of quality Brazilian material, namely a clear, vivid green with a buoyant, lively tone and a transparency that favors cutting brilliance. For collectors comparing hue and tone across the world famous producing regions, this stone sits between the deep, velvety Columbian greens and the darker Zambian greens, while avoiding the yellow bias found in some other locales. Its combination of vivid color intensity, slightly included clarity, excellent polish, and a precision trillion cut make it a technically interesting and visually engaging choice for the connoisseur who values detailed craftsmanship and clear disclosure. If you would like measured viewing in different light sources, detailed facet images, or mounting recommendations to retain color and protect the stone, The Natural Emerald Company will provide the technical support and provenance documentation to assist in your selection.
