3.84 Ct. Bluish Green Prasiolite from Brazil

This prasiolite from The Natural Gemstone Company is a precisely faceted, transparent round weighing 3.84 carats, with physical dimensions of 10.15 by 10.06 by 6.83 millimeters. The stone displays a bluish green hue with medium color intensity, and its cutting style is faceted with a mixed brilliant schema. Clarity has been graded as eye clean when examined at eye level, and the polish meets an excellent standard, producing crisp facet junctions and strong surface luster. The piece has been heat treated, a stable enhancement commonly applied to transform certain quartz material into prasiolite, and the origin is documented as Brazil. These baseline characteristics define both the optical performance and the conservation of value, and they form the objective framework that knowledgeable buyers will use to evaluate suitability for precision jewelry work or a curated specimen collection.

From a craftsmanship and faceting perspective, the mixed brilliant cut employed here combines the dispersion and scintillation benefits of brilliant geometry with the focused color saturation that can be achieved through carefully controlled pavilion and crown proportions. The average crown and pavilion interplay presents as a well controlled light return pattern, and the stone measurements indicate a depth that contributes to saturation while preserving lively scintillation. The depth is 6.83 millimeters relative to the average diameter of 10.105 millimeters, yielding a calculated depth percentage of approximately 67.6 percent, which tends to enhance perceived color depth in medium intensity material. The excellent polish amplifies facet contrast, allowing the crown star facets and pavilion facets to generate distinct flashes and a pleasing mix of brilliance and verve. On bench and under loupe, facet junctions are tight and symmetric, which minimizes light leakage and optimizes the prasiolite for settings that display top view appeal.

Clarity and enhancement disclosure are critical for the informed buyer, and this prasiolite is presented with full transparency. The eye clean clarity grade indicates that no significant inclusions are visible to unaided inspection at normal viewing distances, which supports both high visual appeal and setting versatility. The heat treatment applied is a stable, industry accepted method used to produce prasiolite from suitable precursor quartz material, and the treatment is fully disclosed in accompanying documentation. The natural origin of the rough is Brazil, a region with established supply chains for quartz crystals. The Natural Gemstone Company follows sourcing protocols that emphasize traceability and ethical procurement, including verification of origin, engagement with vetted suppliers, and documentation of enhancements. For a conscious consumer concerned with social and environmental impacts, the combination of origin transparency, treatment disclosure, and company sourcing practices provides assurance that the gemstone has been integrated into the market with attention to responsible conduct.

In practical application and in a responsibly assembled collection, this 3.84 carat round prasiolite occupies a compelling niche. The size and round outline make it suitable for a prominent solitaire ring, an elevated halo composition with white diamond accents, or an elegant pendant where the mixed brilliant cut can interact with directional light. Quartz has a Mohs hardness of seven, which offers daily wearability when set with appropriate protective design choices, for example a bezel or secure four or six prong setting that reduces the risk of edge impact. Care recommendations include avoiding prolonged exposure to strong chemicals and ultrahigh heat, cleaning with mild detergent and warm water, and periodic inspection of the setting. For the collector who values both gemological quality and ethical provenance, this prasiolite presents a documented Brazilian origin, disclosed enhancement, precise mixed brilliant faceting, excellent polish, and eye clean clarity, all curated and offered by The Natural Gemstone Company as part of a transparent and conscientious supply chain.
