1.91 Ct. Emerald from Colombia

One beautiful transparent 1.91 carat oval shape Colombian emerald, measuring 9.92 x 8.10 x 4.30 mm, offered by The Natural Emerald Company, demonstrates the qualities that educated buyers seek, and deserves careful attention for both its gemological merits and its aesthetic performance. This gem is cut to a mixed brilliant faceting scheme, combining a brilliant facet arrangement on the crown with a carefully proportioned pavilion, producing optimized light return and scintillation. The clarity is evaluated as very slightly included at eye level, a rarity for emeralds, and these minimal internal features preserve exceptional transparency while serving as natural fingerprint evidence of origin. The vivid color intensity is the dominant attribute, produced by chromium and vanadium trace elements that create a pure, saturated green, and the polish has been graded excellent, ensuring crisp facet junctions and mirror like surfaces. Enhancement is standard, consistent with responsible trade practices for Colombian material, and the origin is Colombia, a provenance that is associated with classic, high quality emerald color and deep market recognition.

The structure of this beryl family gemstone is central to its unmatched sparkle, and several complementary factors work together to create the visual effect. At the microscopic level, emeralds have a hexagonal crystal lattice that, together with a refractive index in the range typical for emeralds, encourages strong internal reflection and limited light leakage. The modest birefringence of beryl introduces subtle internal light separation which, when controlled by a precise mixed brilliant cut and excellent polish, converts incident light into vivid flashes and lively scintillation rather than dull dispersion. The oval outline further enhances apparent color and light play by elongating the color plane and distributing flashes along the major axis, producing broad, velvety greens interspersed with lively pinpoint scintillation from the brilliant facets. The minimal inclusions present do not impede light performance, and the standard enhancement fills minor fissures to improve transparency and stability under normal wear, while remaining an accepted and reversible treatment in the trade. For the discerning buyer seeking a natural Colombian emerald with exceptional color, transparent presence, and a facet design that maximizes both brilliance and depth, this 1.91 carat oval from The Natural Emerald Company is an exemplary choice.
