0.97 Ct. Rubellite Tourmaline from Brazil

This listing describes one transparent 0.97 carat oval rubellite tourmaline from Brazil, presented by The Natural Gemstone Company. The stone measures 6.92 x 6.14 x 3.47 mm, yielding an approximate depth percentage of 53 percent, a proportion that balances color saturation with efficient light return. The oval outline has been fashioned with a mixed brilliant cut, combining a brilliant facet schema on the crown with modified pavilion faceting to optimize scintillation and color distribution. The color presents as a vivid pinkish red, with clean saturation across the table and crown, and the surface shows an excellent polish, with crisp facet junctions and consistent symmetry. Clarity has been graded as slightly included when evaluated at eye level, the internal features do not materially impair transparency or color, and they serve as natural inclusions that assist in origin verification. Enhancement is limited to heat treatment, a stable and commonly applied technique that intensifies the pure rubellite tones while preserving natural character.

From a cutting and craftsmanship perspective, the mixed brilliant design has been executed to emphasize both flash and face up color, a considered choice for richly colored tourmalines. The crown carries a series of kite shaped and triangular facets that disperse light into controlled flashes, while the pavilion has been adjusted with angular facets that return light through the body in a way that minimizes excessive windowing. The cutter oriented the rough to maximize face up color, taking into account pleochroic tendencies that are inherent in tourmaline, which can shift apparent hue with viewing angle. Facet polish quality is excellent across both crown and pavilion, with minimal polish lines and no detectable polishing pits. The slightly included clarity grade reflects small natural features that are typical for Brazilian rubellite, and conscious facet planning was used to place inclusions away from primary light paths to preserve brightness. The result is a gem that reads as visually clean to the unaided eye while maintaining a natural internal fingerprint.

When comparing brilliance to more familiar gems, rubellite displays a distinct visual behavior that differs from diamond and corundum. Tourmaline refracts light with an index in the neighborhood of 1.62 to 1.64, whereas diamond is approximately 2.42, and corundum variants such as sapphire and ruby are about 1.76 to 1.77. That means rubellite will not exhibit the same degree of white light return or fire as diamond, and it will show less dispersion than diamond as well. Against corundum, rubellite still presents a warmer and more saturated body color, even if overall light reflection is somewhat less brilliant in pure white light. What rubellite offers instead is intense color driven brilliance, where strong saturation and controlled facet architecture create high internal contrast and lively scintillation. Pleochroism in tourmaline contributes to dynamic color shifts as the stone is rotated, producing flashes of deeper red and vivid pink that a purely colorless high refractive index gem cannot emulate.

For designers, collectors, and connoisseurs seeking a colored gem with technical refinement, this 0.97 carat Brazilian rubellite is a compelling choice from The Natural Gemstone Company. The size and proportions are well suited to ring and pendant settings, and the Mohs hardness of about 7.0 to 7.5 provides practical durability for everyday wear when set with appropriate protective design. Heat treatment applied to this stone is stable and intended to reveal the optimum vivid hue while preserving transparency. If you value a gem whose optical personality is defined by saturated color, purposeful faceting, and artisan level finishing, this rubellite stands apart from more common stones by offering a combination of lively scintillation, vivid color intensity, and natural inclusions that confirm provenance.
