4.24 Ct. Cabochon Tourmaline from Mozambique

This specimen is a translucent green tourmaline weighing 4.24 carats, oval in outline, with calibrated dimensions of 10.82 x 8.87 x 5.07 mm, exhibiting a length to width ratio of approximately 1.22. The cutting style is a traditional cabochon, with a smooth domed face and a rounded pavilion, and the height to length proportion yields a relatively high dome at approximately 47 percent of the length, an intentional proportion chosen to enhance light scattering and to maximize apparent color saturation in transmitted light. The cabochon shape and dome profile were executed with attention to symmetry and axis alignment, resulting in a balanced silhouette suitable for bezel and closed back settings, while the dimensions make the stone versatile for rings, pendants, and bespoke settings.

Color assessment indicates a medium color intensity in a primary green hue, with subtle yellow green undertones that are typical of Mozambique tourmaline, and the translucency allows for pleasing internal glow without the opacity that would mute color vibrancy. Clarity is graded as very slightly included at eye level, with fine internal growth features and minor feather and needle like inclusions that are stable and do not impact structural integrity. These inclusions contribute to the gemstones natural character, and the cutter positioned the c axis to present the most uniform color plane, reducing apparent pleochroism and optimizing the visual balance of hue and tone. The origin is Mozambique, and no treatments or enhancements have been applied, preserving the material in its natural state.

Surface workmanship is of high standard, with an excellent polish that produces a clean, vitreous luster across the dome, and precise girdle formation that facilitates secure mounting. The cabochon finish enhances the gemscape and provides a soft, luminous reflection rather than facet brightness, which is desirable for collectors and designers seeking a classic, organic presentation. For clients and trade partners evaluating stability and care, routine cleaning with mild detergent and a soft brush is recommended, avoiding ultrasonic cleaning due to the presence of natural inclusions. The Natural Gemstone Company offers this piece as a natural, unenhanced representative of Mozambique green tourmaline, suitable for connoisseurs who prioritize provenance, fine cutting proportions, and intact natural character.
