5.69 Ct. Bluish Green Prasiolite from Brazil

This exceptional prasiolite, weighing 5.69 carats, represents a premium offering for the discerning buyer who values size coupled with quality. At 5.69 carats, this stone sits well above the common sizes encountered for natural prasiolite in fine faceted form, making it immediately noteworthy for collectors and jewelry designers who prioritize presence and proportion. The round shape, combined with a mixed brilliant cut, allows this larger carat weight to translate into significant visual impact when set, producing a substantial surface diameter and lively face up appearance. Dimensions measure 12.05 by 12.02 by 7.40 millimeters, which yields a depth proportion of approximately 61.4 percent, an excellent balance that preserves weight while maintaining scintillation and light return, characteristics that educated buyers recognize as indicators of premium cutting strategy. The Bluish green hue of this prasiolite is described as intense, a color intensity that elevates its desirability, and the transparency of the material allows the color to be fully appreciated at a glance, reinforcing the value inherent in a 5.69 carat stone that is both visually commanding and technically well cut.

From a gemological perspective this prasiolite offers attributes that align with high quality grading, making it suitable for inclusion in elevated jewelry pieces or refined collections. The cutting style is faceted, executed as a mixed brilliant cut, which combines a brilliant crown with step or pavilion facets to optimize both brilliance and color saturation, particularly effective in quartz varieties where dispersion is modest compared to high index gems. Clarity is assessed as eye clean, evaluated at eye level, which means that no inclusions are visible to a trained observer without magnification, a critical advantage in a larger stone where internal features can otherwise become more conspicuous. The polish is excellent, indicating well executed facet symmetry and surface finish that enhance light performance and the tactile quality of the gem. As a prasiolite, this gem is a green to bluish green variety of quartz, offering a durable Mohs hardness of seven, which supports everyday wear in rings and pendants while still requiring thoughtful setting and care to preserve its excellent polish and intense color.

Origin and treatment are important factors for informed purchasing, and this prasiolite is sourced from Brazil, a region known for producing clean, well colored quartz varieties that frequently achieve commercial and collector status. The stone has been irradiated to achieve its bluish green tone, a common and widely accepted enhancement for prasiolite that produces stable color when properly performed and disclosed. Full transparency regarding enhancement is a hallmark of our practice at The Natural Gemstone Company, and we provide complete information to support an educated purchase decision. For buyers concerned with long term stability, modern irradiation treatments for prasiolite are generally stable under normal wear conditions, however exposure to prolonged intense heat may alter color, so recommended settings and care practices can prolong the ideal appearance. This specimen, with its rare combination of 5.69 carats, intense color, eye clean clarity, mixed brilliant faceting, and excellent polish, represents a compelling value proposition for collectors and designers who seek a substantial, attractive, and responsibly disclosed gemstone.
