1.24 Ct. Emerald from Colombia

This GUBELIN certified Colombian emerald offered by The Natural Emerald Company is a transparent 1.24 carat gem, cut in an Asscher octagon shape, with precise dimensions of 7.14 by 6.99 by 3.88 millimeters, clarity grade recorded as very slightly included, evaluated at eye level, vivid color intensity, excellent polish, and a standard enhancement consistent with trade practice. The certification from GUBELIN confirms both origin and the gemological observations that define this stone, providing independent verification of the material attributes that specialists rely upon. The Asscher octagon outline yields a restrained classical silhouette while preserving the necessary material to optimize color saturation and light performance, making this emerald ideal for connoisseurs who value both provenance and optical precision. The combination of weight, dimension profile, and clarity allows this stone to be set in a variety of designs, while the certification gives buyers assurance regarding origin, enhancement treatment, and the authenticity of the visual grading.

The geometric faceting of this Asscher cut is executed to maximize controlled light play through a series of broad step facets on the crown and pavilion, a large table that preserves color depth, and well proportioned trimmed corners that produce the octagonal outline. The Asscher arrangement yields concentric rectangular steps that create a hall of mirrors effect, producing alternating zones of bright return and dark contrast that emphasize the internal color and give motion to the face up appearance. The measured pavilion depth of 3.88 millimeters equates to 54.9 percent of the average of the length and width, a proportion that balances light return with color retention, avoiding the common pitfalls of over deep pavilions that darken the gem, or overly shallow pavilions that produce windowing. Facet junctions are cut to precise symmetry so that light traverses the crystal lattice with minimal leakage, and the bevelled corners reduce the risk of chipping while contributing to the controlled channeling of light around the perimeter. The geometric discipline of the faceting plan is intentional, calibrated to exploit the refractive index and birefringence behavior of natural emerald, so that each facet plane acts as a reflective engine that alternates scattering and guided return, producing scintillation that reads as lively without compromising the saturated green body color.

Color and clarity interact intimately with the faceting design in this stone, the vivid color intensity is evenly distributed across the table, and the transparent nature of the material allows internal light to be modulated rather than absorbed, resulting in a rich, luminous green that reads as both deep and lively under varied lighting. The clarity grade, documented as very slightly included at eye level, indicates inclusions that are minor and commonly internal to Colombian emeralds, and in this example they are positioned and accommodated by the step cut so that they contribute to rather than detract from the overall character. Because the step facets are expansive, inclusions are often framed by planar facet edges, reducing their visual impact and integrating them into the hall of mirrors optical sequence. The standard enhancement noted on the GUBELIN report is consistent with traditional clarity enhancement techniques used for emeralds, and when professionally executed and disclosed, this treatment stabilizes the stone and enhances appearance without materially changing the gemological identity. For the technical buyer, the balance achieved here between saturation and transparency is a critical virtue, because it preserves the natural Colombian color signature while allowing the faceting geometry to articulate scintillation and depth.

Craftsmanship is evident in the excellent polish and in the geometrical symmetry that defines this piece, facet junctions are crisp and flat, surface finish is mirror like, and the table plane is precisely aligned to the pavilion axis to ensure predictable light behavior in wearable configurations. These finishing standards are important for settings where light directionality matters, for example in higher profile settings that expose the crown to top light, or in bezel mounts where the metal plane interacts with the stone perimeter. Given the Asscher octagon geometry and the moderate depth proportion, recommended mounting strategies emphasize protection of the corners and accessibility for cleaning to preserve the integrity of the enhancement, a tight but skilled prong setting or a subtle bezel will protect the girdle and support the geometry while allowing the step facets to perform. At The Natural Emerald Company we emphasize provenance, cutting integrity, and truthful disclosure, and this GUBELIN certified example embodies those principles by combining Colombian material character, precise Asscher faceting, and professional finishing, offering a technically minded customer a specimen that performs predictably under gemological scrutiny, and that integrates readily into high quality jewelry designs.
