3.97 Ct. Emerald from Colombia

This listing describes a transparent 3.97 carat Asscher octagon shape green emerald, with dimensions 9.86 x 9.80 x 6.69 mm, originating from Colombia, one of the most respected sources for classic emerald character. The stone has an Asscher cut, a clarity grade of slightly included evaluated at eye level, a medium color intensity, excellent polish, and a standard enhancement typical for natural emeralds. The Asscher geometry yields a square outline with cropped corners and concentric step facets, which emphasizes symmetry and a refined faceted architecture. The weight and table dimensions place the gem in a size class suited to prominent center stone settings, while the transparency and medium color intensity provide a balance between presence and wearability for a range of jewelry designs.

The Asscher cut in this emerald is executed with attention to proportional planning, producing broad step facets and a pronounced pavilion depth that encourage linear light return and controlled flashes of luster. The slightly included clarity grading indicates the presence of natural internal features, which are common in emeralds, and which in this specimen do not significantly obstruct face up transparency. Excellent polish enhances facet junction sharpness, contributing to crisp reflections along the step facets and to clear demarcation of the concentric signature that the Asscher form creates. The near square girdle measurements of 9.86 by 9.80 mm produce a pleasing balance between table size and pavilion depth, and the 6.69 mm height provides sufficient depth to retain color saturation while avoiding a heavy, opaque appearance. The overall optical design balances the classical hall of mirrors effect characteristic of Asscher cutting with the color and internal character expected of a Colombian origin emerald.

Optical performance varies with lighting conditions in predictable ways, and understanding these interactions helps in selecting settings and uses that will best show the stone. In bright natural daylight, particularly under northern sky light or indirect sun, the medium color intensity reads as a clear, vivid green with good tonal balance, and the step facets generate broad, even flashes rather than the pinpoint scintillation of brilliant cuts. Under direct sunlight, the stone displays stronger contrasts between light and dark facet planes, enhancing the geometric hall of mirrors appearance, and the green appears slightly richer as the higher light levels emphasize color saturation. In warm incandescent or candlelight, the green shifts subtly, appearing marginally softer and warmer in tone, and the stone yields a gentle glow across its facets, with less stark contrast than under daylight. Under cool white LED or fluorescent sources, the green may appear slightly cooler or more mint leaning, and the sharpness of the step facets gives distinct linear reflections. Under focused spot illumination, such as display lighting, the excellent polish produces crisp, high contrast reflections that emphasize the Asscher architecture, while inclusions may become more noticeable as bright facet reflections traverse internal planes. Overall, the combination of transparency, medium saturation, and step cutting makes this emerald responsive and predictable in color and luster across diverse lighting environments.

From a practical and design perspective, this Colombian Asscher emerald is well suited to formal ring settings, solitaire pendants, or multi stone compositions where the stone can be secured and viewed from the table face to appreciate its step facet pattern. The slightly included clarity level and standard enhancement are consistent with responsible use in everyday jewelry when the stone is properly set and maintained, and it is advisable to protect the girdle and pavilion during setting to avoid stress on natural features. Routine care involves avoiding harsh chemicals and extreme thermal shock, and standard professional inspections will help ensure the setting remains secure. Given its dimensions and presence, this emerald performs well as a centerpiece, providing architectural elegance rather than overt brilliance, and it pairs particularly well with metal styles that emphasize geometry, such as bezel or four prong settings that allow the Asscher outline to remain visually prominent. The Natural Emerald Company confirms Colombian origin and provides transparency on the stone attributes to assist in specifying mounting and care. This emerald offers a clear combination of classical cut form, dependable optical behavior, and natural character, suitable for collectors and designers seeking a finely polished, well proportioned gemstone with established provenance.
