1.11 Ct. Cabochon Paraiba Tourmaline from Nigeria

One beautiful transparent 1.11 carat cushion shape greenish blue paraiba tourmaline is presented with dimensions of 7.19 x 5.34 x 3.60 mm, expertly fashioned in a sugar loaf cut to emphasize depth and color. The gem exhibits a medium color intensity, with a greenish blue tone that is characteristic of copper bearing paraiba material from Nigeria, and it carries a clarity grade of slightly included, evaluated at eye level, which preserves its transparency and visual appeal. The surface shows an excellent polish, and the stone has been heat treated as an enhancement to stabilize and optimize its hue. The cushion outline and the sugar loaf cutting style create broad, even facets that allow the internal color and luster to be read easily in a ring or pendant setting, while the modest inclusions remain unobtrusive under normal wear conditions.

In direct comparison to more common gemstones, this paraiba tourmaline stands apart primarily by virtue of its vivid inner glow and unique chromophore driven coloration, rather than by raw brilliance measured solely by refractive index. Unlike aquamarine, which typically reads as a paler, pastel blue, this paraiba maintains saturated, neon adjacent tones that deliver a strong visual impact at a modest carat weight. Compared with emerald, which often shows significant inclusions that interrupt light flow, this tourmaline balances clarity and color in a way that preserves both depth and sparkle. When set against blue sapphire, which can demonstrate high luster and strong dispersion, the paraiba distinguishes itself through its rare copper influenced fluorescence and perceived luminosity, which gives the stone a lively, almost internal radiance. While diamond exhibits superior dispersion and scintillation by virtue of its high refractive index, the paraiba’s combination of color intensity, cutting proportions, and excellent polish produces a distinct brilliance that is more closely associated with color saturation and light emission than with fire alone. Offered by The Natural Gemstone Company, this Nigerian paraiba tourmaline is a specimen that will attract attention for its uncommon hue, polished finish, and the compelling presence that copper bearing tourmalines uniquely provide.
