3.54 Ct. Bluish Green Prasiolite from Brazil

This prasiolite offered by The Natural Gemstone Company is a beautifully transparent, bluish green oval, weighing 3.54 carats, with exact dimensions of 11.25 x 9.52 x 5.87 mm. The gem is faceted in a mixed brilliant cut, combining step and brilliant faceting to maximize both color and sparkle, and it has an excellent polish that produces crisp facet junctions and lively surface reflection. Clarity is graded as very very slightly included, evaluated at eye level, which means the stone appears clean to the unaided eye and retains exceptional visual purity for a stone of this size. Color intensity is described as intense, a saturated bluish green that reads as elegant and vibrant under both natural and artificial light. Enhancement is irradiated, a standard and stable treatment for prasiolite that produces vivid green tones while preserving the mineral structure, and the gem originates from Brazil, a well known source for high quality quartz varieties.

For an educated buyer, the clarity grade and cutting style are as important as color. Very very slightly included at eye level indicates the inclusions are minimal and are unlikely to affect durability or brightness, making this prasiolite suitable for fine jewelry settings. The mixed brilliant cut is specifically chosen to balance light return with color saturation, the pavilion facets scattering light into the body of the gem to deepen the bluish green, while the crown facets provide scintillation and fire. The excellent polish enhances the stone’s visual appeal and ensures that light moves cleanly across the surface without diffusion. From a gemological perspective, prasiolite is a green variety of quartz, related to amethyst and citrine, and when properly irradiated it achieves a stable, attractive color that is resistant to normal wear and household light. The Brazilian origin further supports its desirability, as Brazil has a long history of producing prasiolite with consistent crystalline quality and good clarity.

When compared to famous historical gemstones, this prasiolite offers a unique and accessible expression of green color that captures some of the qualities admired in storied stones, while remaining distinct in composition and value proposition. The Dresden Green Diamond is famous for its rare natural green hue and historical provenance, and while prasiolite does not share the diamond structure or the extreme rarity of natural green diamonds, the 3.54 carat oval here exhibits an intense green presence in the manner that made historical green stones so visually arresting. Emeralds such as the Chalk Emerald display deep, velvety green tones with typical inclusions known as jardin, which affect how light travels through emeralds. By contrast, this prasiolite’s very very slightly included clarity gives it a cleaner window for light, yielding a more transparent, crystalline appearance. In terms of brilliance and fire, prasiolite will not display diamond like dispersion, yet the mixed brilliant cut allows it to play with light in a way that is reminiscent of finely cut gems from history, producing flashes of brightness across its surface and a stable, attractive color that is easier to care for than many highly included or fragile historical emeralds.

For collectors and designers looking for a gemstone that combines historical sensibility with practical advantages, this prasiolite is an exceptional choice. Its 3.54 carat weight and generous measurements make it an ideal center stone for a ring or pendant, and its clean eye level clarity means it will photograph and wear exceptionally well, without the need for deep bezel settings or heavy protective mounts. The irradiated enhancement is industry standard for achieving the vivid bluish green seen here, and when performed and documented correctly, irradiation is a permanent treatment that will maintain the stone’s appearance under normal conditions. The Natural Gemstone Company can provide detailed images, light performance documentation, and sourcing information on request, and we welcome inquiries about custom mounting options that showcase the mixed brilliant cut to its fullest advantage. For the educated buyer seeking a gem with strong visual impact, verifiable origin, and sound gemological characteristics, this prasiolite represents a compelling balance of beauty, durability, and provenance.
