3.75 Carat Natural Loose Bicolor Tourmaline Stone Emerald Cut Afghan Gemstone

Mined from the famous pegmatite deposits of the Panjshir Valley, Afghanistan, this 3.75 Carat Natural Loose Bicolor Tourmaline showcases a striking, naturally occurring dual-tone color distribution, seamlessly transitioning from a cool mint green to a warm, soft peach-pink within a single crystal. Precision-crafted into an iconic emerald cut, its crisp rectangular silhouette and concentric parallel step facets produce an elegant "hall-of-mirrors" optical effect that beautifully frames the sharp bi-color boundary. The gemstone boasts superior eye-clean clarity and exceptional crystal transparency, allowing light to move fluidly across both color zones without dark extinction or cloudiness. Completely natural, unheated, and untreated, this pristine 3.75-carat Afghan tourmaline offers rare bi-color symmetry paired with ideal ring-ready proportions, making it a sophisticated centerpiece for an East-West set ring, a custom pendant, or a distinguished fine gemstone collection.
