0.11 Ct. Bluish Green Paraiba Tourmaline from Brazil

This oval shaped bluish green Paraiba tourmaline from Brazil weighs 0.11 carat, and measures 3.97 by 2.68 by 1.66 millimeters. The stone is cut in a mixed brilliant style, combining a faceted crown with a step faceted pavilion to maximize both brilliance and color delivery. Clarity is graded very slightly included at eye level, indicating minor internal features that do not detract from overall transparency. Color intensity is medium, producing a balanced bluish green tone that is neither pastel nor deeply saturated. The polish is excellent, resulting in crisp facet junctions and smooth table and pavilion surfaces. The stone has been heat treated, a stable enhancement commonly applied to tourmaline to refine color uniformity, and it is offered by The Natural Gemstone Company with full disclosure of origin and treatment. At its small dimensions this gem is well suited for delicate ring or pendant settings where its color can be viewed against both metal and skin.

Under different lighting conditions this Paraiba tourmaline displays predictable and attractive variation. In natural daylight, particularly in cool northern light, the medium intensity bluish green reads as lively and slightly more blue, with strong internal reflections from the mixed brilliant cut producing clean scintillation. In bright direct sunlight the stone exhibits pronounced brilliance and flashes of electric blue at facet junctions, while the medium color maintains depth without appearing overly dark. Under warm incandescent light the color shifts subtly toward the green side of the spectrum, presenting a softer, warmer hue and enhanced apparent saturation, with the excellent polish producing glimmering highlights. Fluorescent and cool LED lighting accentuate the stones blue components, creating a vivid, crisp presentation that emphasizes the Paraiba character. In low light environments the gem retains a gentle glow due to its transparency and cut, though scintillation diminishes and the medium color becomes more subdued. When set in open backed or bezel settings the stone responds well to contrast against metal, with white metals enhancing brightness and yellow metals warming the tone. The overall result is a finely cut, well finished Paraiba tourmaline that offers versatile visual appeal across light sources, presented with transparency and provenance by The Natural Gemstone Company.
