Customer satisfaction, accurate descriptions and transparency are extremely important to me. Each gemstone is carefully selected and described according to the information provided by the independent gemological laboratory. DESCRIPTION Impressive 100% natural Zambian emerald weighing 4.28 carats, accompanied by an IGI – International Gemological Institute Colored Stone Report. This emerald immediately stands out for its lively and saturated green appearance, clearly visible in the actual photographs. Under direct illumination, the stone displays bright green reflections and an attractive depth of color, giving it a strong visual presence. With measurements of 9.87 × 9.29 × 6.13 mm, the gemstone has an attractive almost-square face-up shape, while retaining the elegant cut corners and geometric step facets characteristic of the classic Emerald Cut. A particularly interesting point is that IGI officially classifies this 4.28 ct natural emerald as Transparent. Its combination of substantial carat weight, transparent classification, attractive green appearance, Zambian origin and independent IGI certification makes it suitable both for a gemstone collection and as the centerpiece of an important bespoke ring or pendant.

OPTICAL AND PHYSICAL PROPERTIES As reported by IGI: Refractive Index: 1.577 – 1.583 Birefringence: 0.006 Optic Character: Uniaxial Specific Gravity: 2.72 NATURAL CHARACTERISTICS Natural emeralds characteristically contain internal features created during their natural geological formation. This gemstone displays visible natural internal characteristics, documented by IGI as: “Natural Inclusion(s) Pattern.” These inclusions are part of the natural identity and individual character of the emerald. The macro photographs have intentionally been taken at significant magnification to allow buyers to inspect the gemstone closely. Consequently, inclusions and internal characteristics may appear considerably more evident in the photographs than when the gemstone is viewed at normal size. COLOR & APPEARANCE The actual photographs show an attractive lively green color with good saturation and bright reflections under direct illumination. The combination of the gemstone's 6.13 mm depth and almost-square emerald-cut proportions gives the stone a substantial appearance, while the step-cut facets produce attractive geometric reflections across the surface. The stone is officially classified by IGI as: GREEN – TRANSPARENT The description of the color and visual appearance above is based on the actual photographs, while the official color and transparency classification remains exactly that stated by IGI. No claims regarding chromium content or other chemical causes of color are made, as these are not specified in the accompanying laboratory report. PHOTOGRAPHY & COLOR DISCLAIMER The photographs were taken to represent the gemstone as accurately as possible. Please note that gemstone colors may appear slightly different depending on lighting conditions, viewing angle, monitor calibration, screen settings and the device used to view the images. Some photographs are taken under direct illumination specifically to show the gemstone's color, transparency, internal characteristics and response to light. Macro photographs considerably magnify the gemstone and may make natural inclusions appear more visible than they are when viewed at normal size. Please carefully examine all photographs, as they form an integral part of the description. SHIPPING The gemstone will be carefully and securely packaged to ensure maximum protection during transport. Tracked and insured shipping will be provided. The gemstone will be supplied with its accompanying IGI Colored Stone Report No. 831616004.
