6.01 Ct. Bluish Green Prasiolite from Brazil

This 6.01 carat bluish green prasiolite presents as a transparent, expertly faceted oval, with exact dimensions of 13.29 by 11.20 by 7.32 millimeters, a form factor that balances presence with wearability. The cutting style is faceted with a mixed brilliant schema, combining a brilliant crown facet arrangement with a modified pavilion geometry to maximize both scintillation and color return, delivering a lively interplay of pinpoint flashes and broad facet sheen. The depth proportion measures approximately 60 percent based on the length and width, a depth that supports strong light return without sacrificing spread, and the stone displays an even girdle thickness that contributes to stable mounting. Clarity is graded eye clean at typical viewing distance, which means that under unaided inspection the stone presents an unobstructed visual field and allows the faceting architecture to perform without distraction. The polish is excellent, with facet junctions rendered with crispness and facet surfaces finished to a high optical clarity that minimizes surface diffusion and enhances the gem s apparent transparency. This specimen is an irradiated prasiolite, a controlled enhancement applied to stabilize and deepen the bluish green hue, and the material traces to Brazil, a source known for well formed quartz crystals with consistent crystalline clarity and color response.

Color characteristics are central to the appeal of this prasiolite, and the piece exhibits an intense color intensity with a primary hue of bluish green, manifesting a high saturation and a medium to medium deep tone that reads as richly colored without appearing overly dark. The mixed brilliant cut complements the hue by creating a balance between pavilion facet angles that emphasize internal light return and crown facets that break light into scintillating pulses, producing a sensation of depth and liveliness across the oval plane. Irradiation has been applied as a deliberate enhancement to shift and consolidate the color palette, and the result is a uniform saturation across the table and face up view, with minimal color zoning and limited pleochroism typical of quartz. Optical parameters for quartz place the refractive index in the range of approximately 1.544 to 1.553, with modest birefringence that does not interfere with the visual purity on a stone of this clarity. The combination of intense color, a precise mixed brilliant faceting plan, and excellent polish yields a prasiolite that offers both attractive broad facet flashes and fine scintillation, a balance that appeals to connoisseurs who assess both optical performance and color quality.

This prasiolite is highly versatile for adornment, equally suited to elevated everyday wear and formal, statement settings. At 13.29 by 11.20 millimeters the stone occupies a scale suited to a signature ring head or a pendant focal point, and it functions well as a solitaire, a halo center, or as the principal element in a multi stone composition. For practical settings, a four or six prong open setting will maximize light exposure and brilliance, while a low profile bezel will offer protection for active wearers without unduly muting the face up presentation. For a formal aesthetic, pairing the bluish green hue with white metals such as platinum or white gold will emphasize the gem s cool undertones, whereas yellow or rose gold will introduce a warm contrast that enhances the green component and produces a vintage character. The material is quartz with a Mohs hardness of seven, providing reasonable resistance to everyday wear, though standard care recommendations apply, avoid hard knocks and aggressive chemicals, and consider periodic inspection of the setting to maintain security.
