8.07 Ct. Prasiolite from Brazil

This 8.07 carat round prasiolite presents a precise combination of size and optical refinement, measured at 13.89 by 13.88 by 8.83 millimeters, with a mixed brilliant cut and an excellent polish. The gem is transparent, exhibiting a bluish green hue with medium light color intensity, and it carries a clarity grade of very very slightly included when evaluated at eye level. The piece has been subjected to irradiation, a standard enhancement for prasiolite to stabilize and intensify its green tones, and it is responsibly sourced from Brazil. At The Natural Gemstone Company we document each specimen with full disclosure of enhancement and origin, ensuring that this piece is offered with complete technical transparency and traceable provenance. The round outline and substantial calibre make this stone an appealing candidate for a center stone in a bespoke ring or a striking pendant, where its dimensions will command a strong face up presence without sacrificing light performance.

The mixed brilliant faceting scheme has been executed to balance scintillation with color saturation. The crown displays a conventional brilliant facet arrangement, optimizing the interplay of crown facets and table to produce lively star and flash scintillation. The pavilion is modified to enhance the face up area and to control light leakage, producing return across a range of viewing angles. With a depth of 8.83 millimeters against a nominal diameter of 13.89 millimeters the depth proportion is approximately 63.6 percent, a figure that affords a slightly deeper pavilion that supports sustained color depth while retaining good brightness. Optically, quartz family properties apply, with a refractive index in the range of 1.544 to 1.553, low dispersion at about 0.013, and a specific gravity near 2.65, which together explain the soft, even flashes and the pleasingly moderated fire. The excellent polish contributes to crisp facet junctions and clean windowing control, enhancing contrast and facet delineation which are particularly important in a medium light colored stone to maximize perceived saturation without creating dead zones.

The color statement is a delicate bluish green, described as medium light in intensity, with an even saturation that reads fresh and modern. This hue derives from intentional irradiation treatment that converts precursor material into stable green tones, a common and accepted practice for prasiolite, especially with material originating from Brazilian deposits. The irradiation has been applied to produce a uniform body color with minimal zoning, and the result is a balanced bluish green that stands up well in both white metal and warm metal mountings. For design considerations, framing this gem with a narrow bezel will emphasize its color and protect the girdle, while a fine halo of small brilliant cut accents can increase perceived brightness and create a contrasting frame that makes the center color pop. In solitaire applications the mixed brilliant cut will deliver a lively interplay of flashes and soft broad reflections, ideal for wearers who appreciate a refined, yet energetic, optical character. Care recommendations include avoiding prolonged exposure to intense heat sources and recommending periodic inspection of the mounting, as heat can in some cases alter treated quartz hues.

As a gift, this prasiolite embodies technical excellence and thoughtful provenance, making it an especially striking choice for an important milestone or a moment you wish to mark with something distinctive. The weight and dimensions provide substantial presence, the faceting and polish promise enduring brilliance, and the eye level clarity ensures the gem will read clean and elegant in daily wear. From an artisan perspective the stone adapts well to precision settings and to custom design work where facet alignment and bezel clearance can be optimized to the cutter s original symmetry, allowing a jeweler to showcase both the optical performance and the subtle bluish green character. At The Natural Gemstone Company we are prepared to assist with mounting recommendations, bespoke design consultations, and documentation of the stone s technical specifications and treatment history, ensuring your gift is backed by expertise and full disclosure. Whether set as a center stone for a unique engagement piece, a refined pendant to commemorate an anniversary, or a bespoke creation to celebrate a personal achievement, this prasiolite offers a sophisticated, technically detailed choice that will remain a memorable and striking present for someone special.
