0.79 Ct. Emerald from Colombia

This specimen is a transparent Colombian emerald weighing 0.79 carat, presented in a classic Asscher octagon shape with dimensions of 5.23 x 5.06 x 3.98 mm. The gem displays an intense color intensity with a pure, vivid green that is characteristic of top Colombian material. Clarity is graded as slightly included when evaluated at eye level, which means inclusions are present but do not significantly obstruct the gem face up. The polish is excellent, delivering crisp facet junctions and a smooth table plane that enhances light return. There has been no enhancement applied to this stone, making its color and clarity wholly natural, and its origin has been traced to Colombia, a source renowned for producing emeralds with superior saturation and chroma.

The Asscher cut on this emerald employs a stepped faceting architecture, composed of concentric rectangular facets on the crown and pavilion that emphasize depth and color instead of scintillation alone. The cropped corner octagon outline maintains symmetry while allowing the table to sit squarely above a deep pavilion. This geometry concentrates the green chroma toward the center of the table, creating a window of saturated color that reads intensely across different angles of observation. Facet alignment and proportionality are key in an Asscher cut, and the precise faceting on this piece produces even facet reflection bands that accentuate the stone core, while the excellent polish minimizes surface diffusion and preserves crisp mirror planes for strong internal contrast.

Color performance is the defining property that makes this emerald stand out in any jewelry setting. The intense saturation and medium to medium dark tone produce a vivid face up color that remains stable under both daylight and artificial lighting. Because the Asscher cut presents a relatively large table with step facets, the gem shows a broad, even field of green rather than highly scattered flashes, which is ideal for designs that prioritize color purity. When set in a white metal such as platinum or 18 karat white gold, the intense green reads with high contrast creating modern, architectural jewelry statements. When set in yellow gold, the same color appears warmer and more classical, the metal reinforcing the lushness of the green. Control of light is essential, and settings that allow light to enter through the pavilion and reflect back through the table will maximize the visual saturation and make the emerald a focal point on the finger or in a pendant.

Clarity and durability considerations inform mounting and wear strategies for this slightly included emerald. The inclusions evaluated at eye level are typical of natural emeralds and contribute to the gem provenance while remaining compatible with secure prong or bezel settings. Depth proportion is approximately 77 percent based on the provided dimensions, which supports good color depth and minimizes windowing in the Asscher format, while the excellent polish reduces the likelihood of surface wear during routine use. Because there has been no enhancement, the stone requires conscientious care against harsh chemicals and extreme thermal shock. Recommended settings by our lapidary team at The Natural Emerald Company include a protective bezel for everyday rings, or a low, four prong secure mounting for pieces where the table should remain prominently visible, such as a solitaire pendant. In all cases, the combination of intense Colombian color, Asscher step faceting, and superior polish ensures that this 0.79 carat emerald will read as a striking, vibrant focal point in any well crafted jewelry design.
