6.10 Ct. Bluish Green Prasiolite from Brazil

One beautiful transparent 6.10 carat round shape bluish green prasiolite, dimensions 12.46 x 12.30 x 7.47 mm, faceted with a mixed brilliant cut, clarity grade very very slightly included evaluated at eye level, intense color intensity, excellent polish, enhancement irradiated, origin Brazil, offered by The Natural Gemstone Company. This specimen stands out immediately for its combination of size and visual clarity, a rare find in prasiolite of this color range. The round mixed brilliant cut brings a lively sparkle that amplifies the gem's natural transparency, while the excellent polish creates mirror like facet surfaces that bounce light cleanly back to the viewer. The bluish green tone is vivid without being overly dark, allowing the stone to register both depth and lightness depending on the setting and lighting, and the eye level clarity grading assures a clean, bright face up appearance that consumers expect from a premium collector grade gem.

When comparing reflective qualities to other gemstones in the prasiolite and quartz family, this piece excels for several reasons. Prasiolite typically displays a softer, more subtle brilliance than high refractive index gems, yet this specimen overperforms because of superior cutting and polish, and because its intense color helps to enhance perceived scintillation. Against common heat treated or lesser cut prasiolites on the market, which often appear washed out or show weak light return, this gem offers more lively flashes and a stronger sense of depth. Compared to green gemstones outside the quartz family, such as peridot, tourmaline and emerald, this prasiolite offers a different but compelling reflective profile. Emeralds typically carry internal inclusions that scatter light and reduce overall brilliance, making them glow rather than sparkle, while peridot can show higher birefringence that sometimes causes doubled facet outlines when not cut optimally. Tourmaline can display strong pleochroism which alters color and reflective behavior depending on angle, sometimes reducing a uniform face up appearance. By contrast, the present prasiolite benefits from uniform transmission through its clean crystal and controlled cutting proportions, producing a balanced return of light with crisp facet contrast and consistent hue across the table.

The mixed brilliant cut is a decisive factor in why this prasiolite outshines many peers in its class. Mixed brilliant cuts combine the light gathering efficiency of a brilliant crown with the depth and color retention of a pavilion arranged to maximize return, which is ideal for quartz group gems where refractive index and dispersion are modest. This blend of cutting strategies produces strong scintillation with small bright flashes that animate the surface, while preserving full color saturation toward the pavilion to maintain the gem's intense bluish green. The excellent polish enhances these effects by minimizing light loss and preventing hazy reflections which can dull smaller or poorly finished stones. In practical comparison to step cut green gems that prioritize color over fire, the mixed brilliant round presents both color vitality and lively reflection simultaneously, making it more versatile for jewelry applications where both sparkle and color presence are desired. The size of 12.46 x 12.30 x 7.47 mm is larger than many prasiolites commonly offered, which increases visual impact, allows for more discernible facet play, and provides exceptional value for the carat weight in relation to market alternatives.

Value, provenance and transparency are all part of the package with this prasiolite from Brazil and with The Natural Gemstone Company. The gem offers a cost effective route to an eye catching green that performs exceptionally well under the light, providing more sparkle and a cleaner face up look than many similar stones at the same price point. The irradiation enhancement used in this material is a stable and widely accepted treatment that yields predictable, durable color improvements, and we fully disclose this to ensure informed purchasing. For buyers seeking a bright, lively green gem with notable size, clean clarity and fine workmanship in the cutting and polish, this prasiolite is a superior choice to many alternatives that sacrifice either color intensity or reflective performance.
