7.90 Ct. Cabochon Tourmaline from Mozambique

This listing describes one transparent green tourmaline, weighing 7.90 carats, presented in a cushion shape with precise dimensions of 10.56 x 10.50 x 8.48 mm, furnished with a traditional sugar loaf cut. The stone has been assessed as very slightly included, evaluated at eye level, which indicates that any inclusions are minor and do not materially detract from the overall appearance when viewed without magnification. Color intensity is classified as intense, and the stone displays strong, saturated green tones across the face up view. The polish is excellent, delivering a smooth reflective surface and well defined facets where present. No enhancement has been applied to this specimen, and the origin is documented as Mozambique. The Natural Gemstone Company provides this description to convey the primary physical and gemological attributes in an objective manner, with the intent that these measured and observed characteristics form the basis for further evaluation or selection by a jeweler or collector.

Visually, the tourmaline exhibits a deep and consistent green, with a tone that reads as medium dark to dark when viewed under standard daylight and photographic lighting. The hue skews toward a classic forest green, with slight cool undertones that contribute to a crisp and natural appearance rather than a yellow or brown cast. Saturation is robust enough to produce strong color presence even under moderate light levels, while the sugar loaf profile enhances perceived depth and richness by presenting a gently domed table that concentrates light within the body of the stone. Subtle variations in hue may appear as the stone is rotated, a characteristic consistent with tourmaline crystallography, and these shifts are modest rather than dramatic, supporting the overall uniformity of the color. The eye level clarity grading indicates that the stone maintains a clean face up presentation, and the excellent polish assists in minimizing any distraction from small internal features.

The sugar loaf cushion cut used for this piece is a traditional shaping that emphasizes weight retention and color concentration, creating a visually substantial face up area relative to the measured dimensions. The proportions, including the slightly rounded corners and domed top, are optimized to preserve carat weight while still allowing for pleasing light return and a rich visual depth. For jewelers and designers, this shape accommodates a variety of settings. A bezel setting will enhance protection and emphasize the stone as a single, uninterrupted form, while a secure four or six prong mounting can present more of the girdle and allow additional light interaction around the edges. Given the 7.90 carat weight and the scale implied by the dimensions, the tourmaline is well suited to a prominent pendant, a substantial cocktail ring, or a central gemstone in a bespoke design where the depth and color can be showcased. Care considerations include the standard handling recommendations for tourmaline, which is a gem with good durability for routine wear, but that should be protected from sharp knocks and prolonged exposure to extreme heat or sudden thermal shock.

Provenance and treatment status are important factors in assessing value and suitability for various applications, and this specimen is reported to be of Mozambican origin with no enhancements. The absence of treatments such as heat or irradiation is a determining attribute for collectors and for those who prioritize natural state gemstones. When evaluating this tourmaline for purchase or for inclusion in a finished piece, buyers may wish to request a gemological report for independent confirmation of the attributes noted here, particularly if certification is required for insurance or resale purposes. Color rendition in photographs can vary with lighting and camera settings, so in person viewing or a laboratory grade image is recommended for final assessment. The Natural Gemstone Company can provide supplementary images and can advise on mounting options, compatible settings, and best practices for care and maintenance, ensuring that the gem’s natural character and structural integrity are preserved in any finished jewelry application.
