22.60 Ct. Emerald from Colombia

This GRS certified Colombian emerald presents as a transparent, vivid green asscher-octagon, precisely measured at 17.17 by 16.89 by 11.59 millimeters and weighing 22.60 carats. The stone is faceted in a classic asscher step-cut configuration with truncated corners forming the octagonal outline, producing a series of concentric square steps on the crown and pavilion. Color evaluation registers as vivid in intensity with a well-saturated, medium-deep tone that remains evenly distributed across the table, while clarity is graded slightly included at eye level, consistent with natural Colombian material. Treatment is standard enhancement, and polish is graded excellent, indicating meticulously finished facet junctions, crisp facet planes and a finely executed girdle. This specimen carries the laboratory provenance and documentation expected by discerning collectors and is offered by The Natural Emerald Company.

The geometric faceting of this asscher-octagon is engineered to maximize internal light play through controlled step facets and calibrated pavilion depth. The broad, relatively large table and proportioned crown steps form parallel planes that reflect light in a hall-of-mirrors effect, emphasizing the stone’s color rather than dispersion, and producing deep flashes and layered reflections as the stone is tilted. The stepped pavilion returns light in a systematic, geometric fashion, so the interplay between crown and pavilion steps yields both brilliance and depth even in a stone with notable saturation. Craftsmanship details to note include symmetrical facet alignment across four axes, well-centered table, consistent step widths, and tight facet junctions that minimize light leakage at the girdle. These technical attributes not only enhance visual impact when set in open-profile jewelry, but also preserve the stone’s color intensity when mounted. For clients seeking a statement center with strong optical structure, this 22.60 carat Colombian asscher offers a balance of vivid tone, precise step-cut geometry and professional finishing, and it is presented with full certification and provenance through The Natural Emerald Company.
