4.42 Ct. Cabochon Tourmaline from Mozambique

This listing presents one beautiful transparent 4.42 carat oval bluish green tourmaline, with dimensions of 10.75 by 8.87 by 5.22 millimeters, cut as a cabochon to emphasize its gentle dome and internal character. The gem is graded as very slightly included, evaluated at eye level, which indicates that the stone displays only minor internal features that do not significantly detract from its visual appeal to the unaided eye. Color intensity is medium light, offering a soft and appealing bluish green tone that reads well in both warm and cool settings, and the polish is excellent, providing a clean reflective surface across the cabochon dome. Importantly, this specimen has undergone no enhancement, preserving the natural color and optical properties that are characteristic of fine tourmaline from Mozambique, and reinforcing provenance and authenticity for discerning buyers.

From a gemological perspective, tourmaline is valued for its complex crystal chemistry and range of colors, and this bluish green example benefits from that diversity while also showing attributes that collectors and jewelers prize. Tourmaline typically exhibits refractive indices in the range of approximately 1.62 to 1.64, and a Mohs hardness around 7 to 7.5, which makes it durable enough for most types of jewelry with appropriate care. The cabochon cut is a considered choice for a gem with medium light saturation and some internal character, because the smooth dome can enhance color depth and produce an appealing, even glow without the need for faceting to mask or reduce visible inclusions. The very slightly included clarity grade indicates that the stone is largely clean to the eye, while microscopic and loupe level examination will reveal small natural inclusions, which are often regarded by educated buyers as confirmation of a natural origin rather than a drawback.

The origin of this tourmaline, Mozambique, is noteworthy and adds to its market value for informed collectors and buyers. Mozambique has become an important source of gem quality tourmaline in recent years, producing a range of attractive green, bluish green, and Paraiba type material, and stones from this region are increasingly sought after for their combination of color and clarity. The fact that this gem is unenhanced amplifies its desirability, because many gem buyers prefer natural, untreated material when considering long term value and collectability. For use in jewelry, a 4.42 carat tourmaline of this size and transparency offers versatility, and the cabochon form lends itself beautifully to bezel settings that protect the girdle and edges, while allowing the gem to display its soft luminescence. Whether mounted in a bespoke ring, a pendant that showcases the oval silhouette, or kept as a collector specimen, this stone offers a pleasing balance of size, natural color, and intact surface quality.
