4.44 Ct. Cabochon Tourmaline from Mozambique

This listing presents a translucent, oval shape green tourmaline, weighing 4.44 carats, with precise measurements of 11.02 x 9.01 x 5.07 millimeters. The piece is fashioned as a classical cabochon, exhibiting a smooth domed profile with excellent polish and tight symmetry across the oval outline. The color is best described as medium light green in intensity, with even saturation across the table when viewed face up under standard daylight and halogen viewing conditions. Clarity has been evaluated as slightly included at eye level, with internal characteristics visible as fine needle like inclusions and minor feathering that do not significantly disrupt light transmission given the stone s translucency. This tourmaline is natural with no enhancements, and the documented origin is Mozambique, a region known for producing clean, well colored green tourmalines with stable zoning. The dome height of 5.07 millimeters yields a proportion that is approximately forty six percent of the longest dimension, a depth ratio that produces a substantial visual presence while maintaining appealing light return for a cabochon cut.

From a lapidary and gemological perspective the cabochon cut was executed to maximize the gem s inherent hue and translucency, emphasizing a continuous, unbroken surface that allows color to read uniformly across the crown. The domed profile minimizes the apparent contrast from internal inclusions, while the smooth transition to a well finished girdle preserves optical continuity at the stone s perimeter. The excellent polish contributes to a bright surface luster and enhances the perception of clarity, while precise symmetry of the oval outline ensures predictable setability into standard mounting templates. Tourmaline as a mineral species is commonly pleochroic, however this specimen displays a consistent face up color, indicating either subdued pleochroic axes or an orientation of cutting that balances the color vectors for an even appearance. Observed internal features include fine acicular inclusions and localized tiny healed fractures, which are typical for natural material from Mozambique, and which provide credible indicators of natural formation without treatment.

For practical use in jewelry design the 11.02 by 9.01 millimeter oval cabochon is well suited to bezel and halo settings that protect the girdle and distribute stress evenly, given tourmaline s Mohs hardness in the range of seven to seven and a half. An open back or partially open back mounting will allow light to enter the pavilion area and can deepen the perceived color in settings where maximum saturation is desirable, while a closed back metal can produce a softer, more opaque presentation if an antique look is preferred. Bezel settings with a slightly raised gallery permit light from the sides while safeguarding the domed surface from lateral knocks, and flange style prongs may be used when minimal metal exposure is desired. Care recommendations include avoiding sudden thermal shock and strong acids, and when cleaning is required, warm soapy water and a soft brush are recommended, with ultrasonic cleaning avoided if the presence of internal feathering near the surface has not been fully assessed by a trained gemologist.

The Natural Gemstone Company stands behind the provenance and descriptive accuracy of this Mozambique green tourmaline, providing thorough documentation of weight, dimensions, cut style, clarity grade, color intensity, polish grade, and enhancement status. This cabochon will appeal to designers and collectors who value natural, untreated stones with character, specifically those seeking a durable central stone for rings, pendants, or bespoke pieces where translucency and a smooth domed silhouette are desired.
