9.66 Ct. Green Tourmaline from Africa

This specimen is a transparent green tourmaline weighing 9.66 carats, presented in an emerald cut and precision faceted to emphasize clarity and depth of color. The gem measures 12.98 by 11.75 by 9.08 millimeters, reflecting a substantial face up area and a proportion that balances table size with pavilion depth. The color is intense, a rich green that reads consistently across light angles, and the clarity has been evaluated as very very slightly included at eye level, indicating only minimal internal features visible to the unaided eye. The polish is excellent, producing crisp facet junctions and clean reflections, and the stone has been heat treated, a standard enhancement that stabilizes and intensifies color. The material originates from Africa, and this combination of weight, dimensions, and cutting quality results in a gem that presents both presence and refinement in hand set applications.

The emerald cut in this tourmaline was chosen to showcase the stone s color and internal structure with controlled light return and a calm, architectural aesthetic. Step facets and a relatively large table create broad, mirror like flashes rather than a scintillating pattern, which allows the green to appear even and saturated, while the depth of the pavilion contributes to internal color saturation and visual depth. With clarity described as very very slightly included at eye level, the cut has been executed to position and minimize the visibility of any minor inclusions, so that the face up appearance remains clean and lively. The excellent polish enhances the stone s surface integrity, providing sharp facet planes and a high degree of light reflection, which together produce a refined optical presentation whether examined closely or viewed from a conversational distance.

This tourmaline is particularly versatile in design contexts, functioning equally well in understated, everyday settings and in elevated, formal jewellery. In casual applications the gem benefits from settings that emphasize security and wearability, such as low profile bezels or protective prongs, and it pairs well with warm yellow gold for a relaxed, organic look or with rose gold for a contemporary vintage feel. For formal or evening pieces, the emerald cut s dignified geometry translates to classic solitaires in white metals, halo settings that add contrast and emphasis, or architectural designs that echo the stone s step facets for a cohesive, restrained elegance. The gem s 9.66 carat weight and substantial dimensions provide a clear finger presence in ring form, while the same proportions lend themselves to a striking pendant or a bespoke cuff design. The color intensity and measured brilliance allow the stone to move comfortably from daytime environments to evening occasions, maintaining visual impact without appearing overly flashy.

Practical considerations for wear and care are straightforward, and they support the tourmaline s use across situations with appropriate caution. Tourmaline rates approximately 7 to 7.5 on the Mohs scale, making it durable for regular wear when set securely, though it is advisable to avoid heavy mechanical knocks and prolonged exposure to harsh chemicals. Although this example has been heat treated to enhance color, such treatment is stable under normal wearing conditions, however extreme thermal shock should be avoided. Routine maintenance may include gentle cleaning with warm soapy water and a soft brush, and professional checking of the setting is recommended to ensure continued security. The Natural Gemstone Company stands behind the described attributes of this stone, and can provide additional images, measurements, and guidance on suitable mounting options or custom work, helping to match the gem s technical characteristics with a setting that achieves both practical durability and the refined aesthetic appropriate to its quality.
