1.68 Ct. Emerald from Colombia

One transparent Colombian emerald weighing 1.68 carat is presented with an oval outline and precise dimensions of 9.66 x 7.50 x 4.31 mm. The gem has been fashioned with a mixed brilliant cut that combines step and brilliant facets to balance color saturation and scintillation. Color intensity is described as light, with a fresh green tone that reads evenly across the table and crown. Clarity is graded very slightly included when evaluated at eye level, and the stone displays internal features that are characteristic of natural emerald formation rather than fabrications. The surface finish is of excellent polish, and the enhancement is reported as standard, which in emerald trade terminology refers to the customary filling of surface reaching fissures to improve visual appearance and stability. The material originates from Colombia, a source known for producing emeralds with a distinctive, lively green, and the gem is accompanied by objective measurements and descriptive attributes for appraisal and setting planning.

The mixed brilliant cut contributes to the gem appearance by allowing controlled light return together with preservation of color depth. Faceting has been executed to present a broad table and proportionate pavilion, which optimize face up size and brightness while retaining the natural green hue. The light color intensity results in a stone that reads as fresh and lively under natural daylight, while the very slightly included clarity grade means that inclusions are present but do not dominate the eye level view. These inclusions serve as diagnostic features confirming natural origin, and because they are not heavily concentrated in the table region, they do not significantly detract from the gem presence. The excellent polish enhances the gem luster and allows the mixed brilliant facets to interact with light, producing flashes and an even surface reflection. For design considerations, the oval outline and balanced dimensions are suitable for a range of jewelry types, including pendants, earrings, and rings where the setting can be chosen to complement the stone proportions.

Regarding durability, emerald is a variety of the mineral beryl and typically rates between 7.5 and 8.0 on the Mohs hardness scale. For comparison, diamond is rated at 10, sapphire and ruby at 9, and quartz at 7. Emerald hardness places it above many common gem materials but below corundum and diamond, meaning it offers good resistance to surface abrasion while requiring thoughtful care for impact and structural integrity. Natural emeralds frequently contain internal fissures and inclusions and can exhibit preferential planes of weakness, so toughness is a separate consideration from hardness. The combination of moderate to high hardness with commonly included structure means that emeralds can be susceptible to chipping or cleavage when subjected to sharp impacts or pressure at facet junctions. The declared standard enhancement, commonly involving oils or resinous filling agents, improves visual appearance and can help stabilize surface reaching fissures, but treatments do not render the stone impervious to mechanical stress. Conservatively selected protective settings, such as bezels or lower profile prong designs with supporting gallery work, reduce exposure to direct knocks and help preserve the gem in daily wear.

The Natural Emerald Company provides exact specifications and provenance information so that gemologists, jewelers, and collectors can make informed decisions. The Colombian origin is a positive attribute for color pedigree and market recognition, and the combination of 1.68 carat weight, oval shape, mixed brilliant cutting style, and excellent polish results in a gem that is both measurable and eminently workable for custom settings. For maintenance, avoid ultrasonic cleaning and steam treatments, use mild dish soap and a soft brush or cloth, inspect settings periodically for loosened prongs, and consult a professional for reapplication of filling agents if necessary. When planning a setting, consider designs that provide physical protection for the girdle and pavilion while allowing light to access the crown to showcase color and brilliance.
