7.30 Ct. Bluish Green Prasiolite from Brazil

This transparent bluish green prasiolite presents as a round shape weighing 7.30 carat, a notable size for this variety that immediately elevates rarity and market interest. The stone measures 12.29 by 12.43 by 8.62 millimeters, dimensions that translate to a commanding face up presence while retaining balanced depth for optimal light return. Cut in a faceted style with a mixed brilliant design, the crown employs a brilliant facet arrangement while the pavilion is proportioned to support both color saturation and scintillation. Clarity is graded eye clean at standard viewing distance, ensuring unobstructed color and sparkle. Color intensity is described as intense, with the bluish green tone showing even saturation across the table and girdle, and the polish is assessed as excellent, contributing to crisp facet junctions and lively reflections. The piece has been enhanced by irradiation, a stable treatment commonly applied to prasiolite to achieve consistent green tones, and it is sourced from Brazil, a provenance known for producing high quality heated and irradiated green quartz material.

The 7.30 carat weight is central to this gem s appeal and value proposition, because prasiolite of this mass with an eye clean clarity and intense hue is uncommon. Gem pricing behavior for colored stones is nonlinear as size increases, larger specimens command disproportionately higher per carat premiums due to scarcity and the greater difficulty in finding material that combines color, clarity, and clean cutting. In practical terms, the 12.29 by 12.43 millimeter table provides a larger visual impact in jewelry settings, allowing designers to exploit both the mixed brilliant facet scheme for brilliance and the depth for color saturation without sacrificing optical balance. The mixed brilliant approach was selected to maximize both scintillation and color presence, reducing tendencies toward windowing that can occur in shallow cuts, and the 8.62 millimeter depth supports strong internal light performance.

As presented by The Natural Gemstone Company, this prasiolite represents a technically refined specimen for discerning buyers who prioritize measurable attributes, including carat weight, dimensions, cut geometry, clarity grading, color intensity, and surface finish. The irradiated enhancement and Brazilian origin are fully disclosed, aligning with best practices in gemstone trade, and the excellent polish and precise faceting ensure that the stone s optical behavior matches its laboratory descriptors. Prospective purchasers seeking a substantial, eye clean, intensely colored prasiolite will find this 7.30 carat round mixed brilliant cut example to be a rare and technically superior choice.
