6.75 Ct. Yellowish Green Prasiolite from Brazil

This exceptional prasiolite presents as a transparent, yellowish green example that emphasizes premium quality through its substantial 6.75 carat weight, making it notable among collector grade quartz family gems. The material is sourced from Brazil, and its provenance contributes to its desirability given the region known for producing high clarity quartz crystals. The hue sits at a medium color intensity, balanced between a soft green and a warm yellowish tone, yielding an elegant appearance that maintains strong color presence without overwhelming saturation. The gemstone has been heat treated, a standard enhancement for prasiolite that stabilizes and refines the green tone, and the treatment is executed with care so that color distribution remains even and natural in appearance.

The cutting style is faceted with an asscher octagonal geometry, and the cutter has prioritized step cut precision to maximize the characteristic hall of mirrors effect for which the asscher family is prized. The stone measures 11.00 x 10.70 x 7.79 mm, and the proportionate depth relative to the average of length and width is approximately 71.8 percent, which places it in a slightly deeper profile that enhances internal light play and color saturation while preserving table stability. The faceting pattern displays concentric square steps on the crown and pavilion, well aligned corners that produce controlled scintillation, and beveled corners that maintain the octagonal silhouette. The excellent polish promotes clean light transmission and crisp facet junctions, resulting in precise facet reflections and a refined visual texture when viewed face up or in profile.

Clarity assessment is very very slightly included evaluated at eye level, which for practical purposes reads as eye clean to most observers while retaining natural internal characteristics when examined under magnification. The minimal inclusions are well positioned and do not compromise the integrity of the cut or the overall light performance, and they actually assist with verifying natural origin and treatment history upon gemological inspection. Facet symmetry is consistent across the crown and pavilion, and girdle treatment is even and serviceable for fine jewelry mounting. Optical performance benefits from the asscher step geometry, which trades off intense sparkle for deep flashes and layered reflections that reveal subtle changes in tone as the viewing angle moves, a property that complements the medium color intensity of the yellowish green body color.

From a design and investment perspective the 6.75 carat weight places this prasiolite in a premium bracket for colored quartz due to the combination of size, transparency, and cut quality. The stone is well suited to solitaire and halo mounting styles that allow the asscher table and step facets to command visual focus, and it can be securely set in bezel or four prong settings that respect its octagonal form. For buyers seeking a statement center that balances classic step cut elegance with an uncommon green tone, this specimen represents an optimal choice. The Natural Gemstone Company offers this prasiolite as a carefully evaluated piece with documented enhancement and origin information, reflecting our commitment to transparent sourcing and high standards of lapidary craftsmanship.
