1.83 Ct. Emerald from Colombia

This offering from The Natural Emerald Company is a C.Dunaigre certified, transparent Colombian emerald weighing 1.83 carats, presented in an elegant oval shape, with precise measurements of 10.59 by 8.12 by 3.76 mm. The gem carries a clarity grade of very slightly included, evaluated at eye level, a vivid color intensity, and an excellent polish, with standard enhancement fully disclosed. The mixed brilliant cut has been chosen to balance brilliance and color, and the stone presents a lively face up appearance with a rich, saturated green that is characteristic of high grade Colombian material. Certification by C.Dunaigre provides independent verification of these attributes, offering the informed buyer confidence in provenance, treatment disclosure, and accurate grading. The combination of a near two carat weight, high transparency, and vivid saturation makes this emerald notable for both connoisseurs and collectors who value natural origin and documented quality.

From a gemological perspective the clarity description of very slightly included, evaluated at eye level, indicates that inclusions are minimal and do not materially interfere with visual performance when the gem is viewed unaided. Colombian emeralds are renowned for their pure chroma and hue, and this specimen displays those regional hallmarks, with color that reads vividly even under varied lighting. The excellent polish enhances surface smoothness and facet definition, improving light transmission and minimizing surface diffusion of color, which is particularly important for emerald where color is the primary determinant of value. Standard enhancement in emeralds typically refers to the use of colorless oils or resins to fill surface reaching fissures, a long established and accepted practice that is routinely disclosed, and when done professionally it is stable under normal wear, though it benefits from careful maintenance. Taken together, documentation, origin, clarity, and polish contribute to the market value and desirability of this emerald.

The mixed brilliant cut on this oval emerald is a deliberate choice to optimize the gem’s inherent properties of light reflection and color presentation. By combining brilliant style facets with complementary step facets, the cutter has managed the balance between scintillation and color retention, allowing controlled internal reflections to return saturated green light to the observer, while limiting excessive light leakage that can wash out color. The gem’s depth proportion is approximately 40 percent when calculated against its average diameter, a proportion that favors efficient light return and a generous face up appearance relative to its weight. The oval outline increases the apparent size and creates linear movement in the eye, while the facet architecture of the mixed brilliant arrangement produces lively pinpoints of brilliance across the table and crown, enhancing perceived brightness without sacrificing the deep verdant saturation that defines a premium Colombian emerald. In practice this means the stone displays both a clear, saturated field of green, and attractive scintillation at tilt, giving it versatility for both classic and contemporary jewelry designs.

For practical ownership considerations The Natural Emerald Company emphasizes full disclosure and offers guidance on care and setting to preserve the gem’s beauty and value. Because the stone has been treated by standard enhancement, it should be cleaned with warm soapy water and a soft brush, avoiding harsh solvents and ultrasonic cleaners unless a professional gemologist confirms stability. Settings that protect the girdle and expose the table to light will both showcase the color and reduce risk of mechanical damage, and the oval mixed brilliant shape adapts well to bezel and claw settings that allow light to enter and display the vivid hue. For an educated buyer this emerald represents a rare combination of certified provenance, attractive weight, excellent polish, and a cut engineered to amplify both brilliance and color, attributes that make it suitable for investment quality jewelry and discerning private collections.
