The Natural Gemstone Company presents a fine example of Brazilian paraiba tourmaline in a pear shaped silhouette, transparent, weighing 0.16 carat, with dimensions of 5.26 by 2.61 by 1.95 millimeters. This stone exhibits intense color intensity in a bluish green hue, with a clarity grade of very slightly included evaluated at eye level, and it has been heat treated to optimize tone and visual purity. The cutter employed a mixed brilliant faceting scheme combined with an excellent polish to balance scintillation and color transmission, resulting in a gem whose surface and internal reflections remain vivid under direct and diffused lighting. The overall proportions yield a length to width ratio of approximately 2.02, and a total depth of approximately 49.5 percent, a set of proportions that favors elongation and a graceful teardrop profile while maintaining sufficient pavilion volume for efficient light return.
On a technical level the mixed brilliant cut unites a brilliant styled crown with a precision arranged pavilion, producing focused light return and crisp scintillation across the pear outline, while the pointed tip has been faceted to maintain symmetry and to reduce vulnerability when set. The crown facets have been sized and angled to optimize return of the gemore light wavelengths associated with the bluish green chroma, while the pavilion facets are calibrated to reinforce internal light circulation and minimize leakage out of the facets adjacent to the girdle. The excellent polish enhances facet junction crispness, aiding optical performance, and the clarity grade of very slightly included at eye level indicates that inclusions are minor and do not significantly interrupt facet reflections or the saturation of the body color, although they may provide useful fingerprints for identification and origin verification.
Color characterization of this paraiba tourmaline is central to its appeal, and the intense bluish green hue is consistent with copper bearing tourmalines from northeastern Brazil, where trace copper and manganese impart a vivid, almost electric quality to the color. This specimen displays a high saturation level with a medium to medium dark tone, providing a balance between depth of color and surface brightness that allows the stone to exhibit lively fluorescence under strong lighting while maintaining richness in subdued illumination. The stone also exhibits subtle pleochroism, with slightly greener and slightly bluer facets apparent as the gem is rotated, a characteristic that can be used creatively in jewelry design to present desired color alignment. Heat treatment has been applied using controlled protocols common to the trade to refine tone and reduce the visual impact of minor inclusions, and this enhancement is stable under normal wear and professional cleaning methods.
For jewelry applications the pear shape and intense color intensity make this gem a compelling choice for settings that maximize face up presence, including three prong or five prong head designs for rings, tapered or reversed head settings for pendants, and halo settings to amplify apparent size and color contrast. A well executed prong setting will allow maximum light to flood the pavilion and crown, preserving the paraiba effect and scintillation, while a bezel setting will offer enhanced protection for the delicate tip at the expense of some light entry, an acceptable compromise for pieces intended for daily wear. The Natural Gemstone Company can provide guidance on bezel lip profiles and prong configurations to ensure secure mounting without sacrificing optical performance, and we can supply magnified imaging and additional gemological notes upon request, to support bespoke design and certification needs.
