0.86 Ct. Paraiba Tourmaline from Brazil

This GIA certified, transparent, bluish green Paraiba tourmaline weighs 0.86 carat, and measures 8.13 x 5.23 x 2.97 mm. The gem is fashioned in an oval outline with a precision mixed brilliant cut, combining a modified brilliant crown with a calibrated stepped pavilion geometry. This geometric faceting approach is engineered to maximize light play, by optimizing crown facet angles for efficient dispersion and scintillation, while the stepped pavilion facets deepen the perceived color and preserve saturated tone. The result is a dynamic balance between brilliance and color, with lively facet-to-facet reflections and controlled light return that minimize windowing. Clarity is graded as slightly included at eye level, these minor inclusions remain well positioned and do not interrupt the overall transparency or the vivid, intense color intensity noted on the report. Polish is excellent, and symmetry is carefully executed so facet junctions remain crisp, supporting strong contrast patterns and superior face up brightness. Enhancement by heat treatment is disclosed, and the documented origin is Brazil, as recorded on the GIA certificate.

From a technical perspective, the mixed brilliant faceting amplifies the tourmaline s pleochroism, allowing the bluish green hues to shift subtly as the stone is rotated, while maintaining a concentrated core of color in the table view. The crown geometry produces tight, repeatable scintillation patterns, and the pavilion configuration increases effective depth without sacrificing light return, an important consideration in a 0.86 carat oval with these proportions. For setting recommendations, an elevated open gallery will permit maximum light entry and showcase the stone s intense saturation and internal fire, while close attention to orientation will present the dominant blue green face up. The Natural Gemstone Company documents this stone with full lab verification, and I invite you to request the GIA report, high magnification images, and live video to assess the inclusion character and facet interplay. For collectors and connoisseurs seeking a paraiba with technical refinement, notable color intensity, and carefully executed geometric faceting for maximum light play, this Brazilian Paraiba tourmaline represents a precisely cut, gemologically verified option.
