1.96 Ct. Bluish Green Tourmaline from Brazil

This transparent bluish green tourmaline weighs 1.96 carat, and measures 8.72 x 6.93 x 4.93 mm, cut into an elegant oval shape with a faceted profile. The cutter employed a mixed brilliant cut, combining a brilliant style crown with modified pavilion facets, to optimize both color saturation and light return. The gem is eye clean at typical viewing distances, indicating minimal inclusion interference with light transmission. Color intensity is described as intense, with a balanced bluish green hue that occupies a strong position on the saturation scale without appearing overly dark. Polish quality is excellent, the facet junctions are crisp and consistent, and the girdle integrity supports secure setting options. This piece has been heat treated, a stable and well documented enhancement for tourmaline that deepens and homogenizes body color while retaining natural character. Origin is Brazil, a locality noted for producing tourmalines with lively tones and stable crystal structure.

From an optical and technical perspective this tourmaline stands out when compared to more commonly encountered colored stones. Versus emerald, which often exhibits significant inclusions that scatter light and reduce apparent brilliance, this eye clean tourmaline returns light with clearer, more defined reflections, producing stronger facet contrast and scintillation. Versus aquamarine, which tends toward paler, less saturated tones, the intense bluish green of this stone gives a richer face up appearance, making it more visually striking at similar sizes. Compared with corundum varieties such as blue sapphire, the tourmaline has a lower refractive index, and therefore less dispersion or fire, however the mixed brilliant geometry in this cut compensates by maximizing internal reflection and directional flashes, yielding lively contrast and a perceived sparkle that reads as brighter in typical jewelry lighting. The combination of intense saturation, superior polish, and eye clean clarity enhances apparent brilliance, particularly under mixed daylight and artificial illumination. Offered by The Natural Gemstone Company, this gem is a technically refined specimen suitable for collectors and designers seeking a strong color statement with optimized optical performance, and it will deliver consistent brilliance and color depth when set in fine jewelry.
