0.90 Ct. Tourmaline from Tanzania

This listing presents a transparent 0.90 carat oval shape yellowish brown tourmaline, with exact dimensions of 5.88 x 5.20 x 4.25 mm. The gem has been fashioned with a mixed brilliant cut, combining a faceted crown that enhances scintillation with a pavilion designed for optimal light return. Clarity is graded very slightly included, evaluated at eye level, a grade that indicates minor internal characteristics which do not materially interfere with brightness or overall visual appeal. Color intensity is classified as intense, and the stone displays an even saturation across the table and facets. Polish is excellent, and there has been no enhancement applied to alter color or clarity. The natural origin is Tanzania, documented to provide the crystal characteristics observed in this specimen.

The mixed brilliant cut is purposeful for this oval form, balancing brilliant crown facets that create dynamic flashes of light with a structured pavilion that returns light to the observer. The excellent polish ensures that facet junctions remain crisp, allowing clean light transmission and minimizing surface diffusion. Given the very slightly included clarity, inclusions are small and generally not visible through standard mounting positions, so the gem maintains high visual transparency when set. At 0.90 carat and the stated dimensions, the stone is proportioned to sit comfortably as a primary center stone in a ring, pendant, or a compact brooch setting, while the cut proportions preserve depth and face up size.

Under different lighting conditions this tourmaline performs with reliable consistency while revealing a range of warm tonalities. In natural daylight, especially diffused outdoor light, the stone reads as a clear, golden brown with bright, crisp facet reflections, and the intense color presents as a lively warm yellowish brown. Under warm incandescent or halogen light the stone takes on richer honey and amber notes, with increased visual warmth and a perception of deeper saturation. Under cool white LED light the yellow component appears slightly restrained and the stone displays a more biscuit toned appearance, while the mixed brilliant cut continues to deliver noticeable scintillation on movement. In candlelight or other low intensity warm sources the tourmaline shows soft golden flashes and a gentle internal glow, the effect enhanced by the gem transparency and the excellent polish.

Because the gem is natural and untreated, the color and optical behavior are intrinsic properties, and the stone will respond naturally to variations in light source and setting. The combination of intense color, very slightly included clarity, and mixed brilliant cut offers a gem that balances presence and versatility, suitable for designs that favor warm tones and refined sparkle. The Natural Gemstone Company provides this piece with origin information and the stated grading attributes for professional consideration, and the gem is recommended for clients seeking a naturally colored tourmaline with reliable performance across common lighting environments.
