4.48 Ct. Emerald from Colombia

This transparent Colombian emerald weighs 4.48 carats and is fashioned in a classic emerald cut with exact dimensions of 10.62 by 9.09 by 7.04 millimeters. The stone presents a clarity grade of very slightly included evaluated at eye level, which for emeralds translates to minimal internal features that do not interrupt the overall transparency or light transmission. The cut follows traditional step facet geometry with long rectangular pavilion facets and a broad table, and the faceting symmetry yields balanced facet junctions and parallel facet planes. The polish is graded excellent across all facet faces, producing clean facet windows and razor sharp facet edges that minimize surface diffusion. Enhancement is standard, and the finishing work respects the stone structure while maintaining stability for mounting. These measured proportions produce a depth that is approximately seventy one percent of the average of the length and width, a proportion that concentrates color saturation while retaining generous face up presence.

The sparkle of this emerald is a direct consequence of its internal structure, facet architecture, and material optical constants, working in concert to create an effect distinct from brilliant cut gems. The emerald cut relies on broad step facets that generate large planar reflections rather than the small points of scintillation typical of brilliant cuts. In this stone, each step facet acts as a mirror plane, producing broad flashes of lively green and deep color windows that shift with movement and light angle. Because the stone is transparent with very slightly included clarity, internal light paths remain largely unobstructed, allowing multiple internal reflections to stack and reenter the crown as vivid color flashes. The refractive index of beryl yields a strong vitreous luster and a higher internal reflectivity than many other transparent gem species, and the excellent polish on the pavilion and crown facets maximizes that reflectivity while reducing light loss at the surface. The result is a hall of mirrors effect, with layered rectangular flashes and defined facet outlines that give the stone a structural brilliance and depth that is unmatched among step cut gemstones. Pleochroism in emeralds contributes an additional dimension, with subtle shifts between bluish green and pure green tones as the stone is rotated under directional light, enhancing the perception of internal motion and life.

Origin and material chemistry further reinforce the stone character, and this specimen from Colombia exhibits the intense color intensity prized in fine emeralds. The chromophore elements present in Colombian beryl produce a saturated hue with a slight blue bias that keeps the color lively rather than dark, and the intense saturation paired with the stone transparency ensures color face up is both vivid and even across the table. Because the stone retains excellent proportions and bevelled corners typical of high quality emerald cuts, the geometry offers both aesthetic presence and practical durability in settings. The depth driven color concentration is advantageous for collectors and designers who desire a bold green that remains lively rather than appearing washed out. For mounting, the stability provided by the bevelled corner design allows for secure prong settings or low profile bezels, and the excellent polish reduces the need for frequent cleaning to maintain brilliance. This emerald is presented by The Natural Emerald Company with full disclosure of its standard enhancement, and it represents a technical example of how precise cutting, disciplined polishing, and superior material quality combine to create a step cut emerald whose structural reflections and color dynamics yield a sparkle and depth of field that knowledgeable buyers will recognize as exceptional.
