1.80 Ct. Emerald from Colombia

This 1.80 carat emerald cut green emerald from Colombia represents a rare combination of carat weight, proportion and vivid color that discerning buyers will recognize immediately. It measures 7.47 x 6.95 x 4.81 mm, and was fashioned in a classic emerald cut that emphasizes broad step facets and a generous table. The clarity has been graded very slightly included, evaluated at eye level, which means that the stone appears remarkably clean to the unaided eye while retaining the natural internal characteristics that authenticate its origin and natural formation. Color intensity is classified as intense, and the polish is excellent, delivering a clean facet finish and crisp facet junctions. Enhancement is standard, a responsible and accepted treatment in the trade that improves visual transparency and color presentation. At The Natural Emerald Company we select only stones that combine natural origin, balanced cutting and honest clarity grading, and this Colombian emerald meets that standard.

From a gemological perspective this emerald is a member of the beryl family, crystallizing in the hexagonal system and colored by trace chromium and sometimes vanadium. Colombian emeralds are globally prized because the trace element chemistry and formation environment there produce a particularly pure and saturated green, often with a slight bluish tone that the market regards as the most desirable expression of the species. Measurable optical properties include a refractive index in the neighborhood of 1.577 to 1.583, and a low birefringence on the order of 0.005 to 0.006. These optical constants translate to a deep, absorbing green that does not rely on fire but instead on depth of tone and internal reflections to convey brilliance, so cut and polish are critical. The very slightly included clarity grade reflects small internal features that are typical for emerald and that often act as identifiers of natural origin, while standard enhancement, commonly performed with oils or resins, stabilizes and fills surface reaching fissures to improve transparency without altering the gemological identity of the material.

The way this stone has been cut and finished is a principal contributor to the exceptional sparkle and presence that make it stand out. The emerald cut uses broad, parallel step facets and a large open table, which for a high quality emerald is desirable because it allows the viewer to appreciate the color and internal character with clarity. Instead of the intense scintillation that diamonds exhibit through numerous small facets, this emerald produces a hall of mirrors effect, where deep flashes and layered reflections move as the stone is tilted, and where the color appears to glow from within. Because the refractive index of beryl is moderate, careful facet planning and excellent polish are essential to maximize internal reflections and surface luster. The 4.81 mm depth is balanced relative to the table and girdle dimensions, which preserves face up spread and enables the step facets to throw broad reflective flashes. In combination with the intense color and very slight inclusions, the result is a gemstone that offers a lively interplay of depth and light, where each facet plane serves to enhance saturation and to channel luminous reflections to the eye.

For the educated buyer this emerald presents a compelling proposition in both aesthetic and investment terms. The carat weight of 1.80 places it in a size class where color quality becomes the primary determinant of value, and the intense Colombian green of this stone is the kind of saturation buyers seek for high end jewelry. The very slightly included clarity grade and standard enhancement are consistent with responsible trade practices, preserving natural character while improving visual performance. The emerald cut lends itself to classic ring and pendant settings that showcase the stone as the central, unfragmented color field, while the excellent polish assures that the gem will sit confidently in light without distraction. At The Natural Emerald Company we can provide additional technical documentation on request, and our team is prepared to advise on setting proportions that preserve the stone geometry and maximize face up brilliance. For collectors who value provenance, natural formation, and the optical interplay that only a well cut Colombian emerald can offer, this gemstone is a singular opportunity.
