2.15 Ct. Yellowish Green Tourmaline from Tanzania

This transparent 2.15 carat radiant shape yellowish green tourmaline measures 8.49 by 6.31 by 5.02 mm, and is faceted in a radiant cut that balances step and brilliant elements to optimize both color and scintillation. The gem originates from Tanzania, and is untreated, with no enhancement reported. Color is described as medium intensity, yielding a fresh yellowish green hue that is evenly distributed across the table. Clarity is slightly included when evaluated at eye level, with minor natural inclusions that do not significantly interrupt the overall transparency or the stone's light performance. The polish is excellent, producing crisp facet junctions and clean reflections, and the combination of proportions and polish allows the tourmaline to deliver well defined facet return and a steady visual depth in hand. The Natural Gemstone Company presents this stone with full specification to assist in appraisal and setting decisions.

Under varied lighting the radiant cut and the tourmaline composition produce distinct visual behaviors. In cool daylight the medium intensity color reads as a clear yellowish green with a slightly more verdant cast along the pavilion facets, and the precise faceting yields even, bright reflections that emphasize the internal clarity and structure. Under warm incandescent light the stone tends to show warmer yellow notes, producing a gentler, more golden green appearance, while maintaining good sparkle from the multiple facet planes. In mixed indoor lighting and under LED sources the gem demonstrates crisp scintillation, with flash patterns that alternate between lighter and deeper green tones as the gem or observer moves. In bright direct sunlight the stone exhibits strong contrast between bright facet highlights and the deeper internal color, enhancing perceived brilliance and the radiant cut geometry. In low light the gem retains a subdued glow rather than extinguishing, owing to its transparency and cut, and the slightly included clarity allows subtle internal reflections that add character without detracting from the overall brightness. The stone may display modest pleochroic tendencies typical of tourmaline, revealing slightly different green and yellow tones at different viewing angles, and the radiant cut helps translate those shifts into attractive directional flashes. For mounting, a setting that allows light access to the pavilion will best preserve these lighting attributes.
