2.35 Ct. Green Tourmaline from Brazil

One transparent 2.35 carat oval green tourmaline, measuring 10.08 by 7.16 by 5.25 mm, presents a carefully faceted gem that balances size and wearability, provided by The Natural Gemstone Company. The cutting style is faceted with a mixed brilliant cut, combining a brilliant faceting pattern on the crown with complementary pavilion facets that enhance return of light and scintillation. Clarity is graded as very very slightly included at eye level, indicating that the stone appears clean to unaided vision with only minimal inclusions visible under careful examination. The color displays medium intensity, a balanced green tone typical of quality Brazilian tourmaline, and the surface exhibits an excellent polish. Enhancement by controlled heat treatment has been applied to optimize hue and clarity, a stable and commonly accepted practice in tourmaline sourcing and finishing. The combination of size, cut, clarity, and polish results in a gem that is both visually appealing and suitable for a range of jewelry settings.

Under natural daylight, the gem reveals its truest medium green, with the mixed brilliant cut producing lively scintillation and crisp facet contrast, allowing subtle internal reflections to animate the stone as it moves. In bright direct sunlight, the facets deliver stronger flashes and heightened contrast, emphasizing the gems internal geometry, while the relatively low dispersion of tourmaline yields refined flashes rather than pronounced spectral fire. Under cool white LED or fluorescent lighting, cooler components of the green may be slightly enhanced, giving a fresher, mintlike appearance, and the polished facets continue to reflect clean, bright highlights. In warm incandescent or candlelight, the gem takes on a softer, warmer aspect, the green appearing richer and slightly warmer, and the pavilion facets return more muted, rounded flashes that produce an elegant, subdued glow. In dim or diffuse light situations, the stone retains presence through internal reflections and the faceted crown provides delicate scintillation, ensuring it remains visually engaging even when light levels are modest.

Practical considerations for setting and wear reflect the stones proportions and optical behavior. The 10.08 by 7.16 mm oval shape and 5.25 mm depth are well suited to classic ring designs, pendants, or custom bespoke pieces where the mixed brilliant cut can be showcased. A four or six prong setting will maximize light entry and display of scintillation, while a well engineered halo or low bezel can protect the girdle without overly restricting light. The very very slightly included clarity permits open style settings that emphasize transparency and light return, while the excellent polish ensures fine facet junctions that contribute to crisp reflections. Heat treatment is stable for normal jewelry wear, and the stone should be cleaned with warm water and a mild detergent or an ultrasonic cleaner in most cases, avoiding harsh chemicals.
