15.57 Ct. Cabochon Emerald from Zambia

This transparent 15.57 carat oval emerald measures 19.49 x 11.62 x 9.04 mm, precisely cut as a cabochon to maximize the stone s intrinsic color and internal light return. The cabochon profile exhibits a well centered dome with even curvature and a polished crown that emphasizes uniform color saturation across the table. Though cabochons lack faceting in the traditional sense, the cutter s approach to symmetry, dome height and pavilion thickness functions as a controlled faceting strategy, directing light to enhance the intense green hue while avoiding windowing or unwanted dark zones. Clarity is graded as slightly included at eye level, with natural internal characteristics that are discrete and stable under normal wear. These internal features, visible only at modest magnification or upon close inspection, contribute to the stone s identity and natural origin without materially compromising transparency. The polish is excellent, yielding a high degree of surface luster and a smooth reflective plane that accentuates the emerald s depth of color.

Enhancement is recorded as standard, consistent with established clarity enhancement methods used for emeralds to stabilize fissures and improve visual appeal. The stone s origin is Zambia, and the material displays the regional color profile associated with Zambian emeralds, namely a deep, slightly bluish medium to intense green with strong saturation. The cutter s decisions reflect an emphasis on weight retention and optimal optical performance, maintaining balanced proportions and a robust girdle area suited to secure bezel or collet settings. For setting recommendations, a full bezel or partial bezel with protective shoulders is advised to protect the domed surface and ensure longevity. The Natural Emerald Company quality control process includes measured dimensions, photographic documentation, and eye level clarity grading, ensuring transparent provenance for discerning buyers. This piece suits a collector or high end jewelry commission who values technical workmanship, authentic natural characteristics, and measurable specifications, offering a sizeable and technically refined example of Zambian emerald material ready for integration into precision jewelry design.
