2.25 Ct. Emerald from Colombia - Muzo

This entry is a transparent C.Dunaigre certified 2.25 carat asscher octagon shape green emerald with dimensions of 8.42 x 8.24 x 5.42 mm, originating from the Muzo mines of Colombia. The stone presents a vivid color intensity and a clarity grade of very slightly included evaluated at eye level, with an excellent polish. The asscher style of faceting is executed to strict proportions, yielding an asscher octagon outline with balanced symmetry and uniform girdle presentation. Enhancement conforms to standard practices for emeralds, and the overall finish and surface condition are consistent with a gemstone prepared for setting and long term wear. The certification by C.Dunaigre provides independent verification of weight, dimensions, origin, and the clarity and color characteristics described, supporting transparent provenance and technical accuracy.

The asscher cut amplifies the intrinsic optical properties of this emerald through a sequence of broad step facets that emphasize depth, table clarity, and directional light return, rather than dispersed brilliance. The octagonal step pavilion and truncated crown create paired mirror planes that guide light down and back up the crown in controlled paths, producing a focused play of light and dark that accentuates the stone s natural green saturation. In a gemstone of very slightly included clarity and excellent polish, these step facets function to reveal internal character without unduly masking color, so inclusions remain discreet at typical viewing distances while the vivid color intensity appears more concentrated. The combination of deep pavilion angles and a well proportioned crown plane enhances the sense of internal glow, allowing viewers to perceive layered reflections and a consistent color field across the table. For precision settings, the asscher octagon configuration also yields predictable light behavior under different lighting conditions, maintaining color fidelity and structural appeal. The Natural Emerald Company presents this specimen with documentation and measured parameters to assist in evaluation and design decisions, matching the gem s optical performance to considered jewelry applications.
