5.81 Ct. Green Prasiolite from Brazil

This exquisite transparent 5.81 carat round green prasiolite from Brazil is a standout example of what The Natural Gemstone Company strives to offer in superior natural gems, the stone measures 11.84 x 11.62 x 7.70 mm, the cutting style is faceted with a mixed brilliant cut, and the clarity is graded as very very slightly included when viewed at eye level, the color shows a pleasing medium intensity, and the polish is excellent, the gem has been heat treated to achieve and stabilize its attractive green hue, a treatment that is standard in quality prasiolite production and which enhances the stone without compromising its natural appeal. Compared to many prasiolites and green gemstones on the market this piece stands out because of its size, transparency, and the careful combination of a mixed brilliant faceting scheme with exacting proportions, many market stones in this category are smaller, more heavily included, or cut in ways that do not maximize light return, while this green prasiolite has been cut and polished to bring out exceptional optical performance, the result is a gemstone that reads as both elegant and vibrant in hand, a choice that gives designers and collectors more flexibility than average material.

The sparkle of this prasiolite is a direct consequence of its internal structure and the precision of the mixed brilliant cut, the gem’s crystalline lattice and high degree of transparency allow light to enter deeply and interact with a dense pattern of precisely angled crown and pavilion facets, the mixed brilliant design places a brilliant facet pattern on the crown to deliver lively scintillation, while incorporating well proportioned pavilion facets to promote effective light return and contrast, every facet junction has been polished to an excellent finish so that light is scattered and returned in sharp, lively flashes rather than being absorbed or diffused, this produces a balance of lively white scintillation and subtle colored flashes that is difficult to achieve with simple step cuts or poorly proportioned brilliants, in practical terms this means that when compared to a similar sized peridot or green quartz cut without such attention to facet geometry this prasiolite will appear brighter, more alive, and less dull under ambient lighting conditions. The medium color intensity of this stone is ideal because it allows the precise faceting to show through, a very dark green can mask the internal play of light and a very pale green can appear washed out, this prasiolite sits squarely in the sweet spot where both color and cut combine to produce an impressive visual impact.

Beyond pure optics this prasiolite offers a value proposition that is difficult to match, when compared to emeralds of similar face up color this stone provides significantly higher clarity and a cleaner face up appearance for a fraction of the price, when compared to tsavorite garnet or high end green tourmaline it delivers comparable brilliance and color charm while being less common in such large, clean rounds, and when compared to untreated or poorly treated prasiolite on the market it shows the benefit of responsible heat treatment that enhances color without introducing instability. The dimensions and round shape give strong presence on the finger as shown in the included photos, the 5.81 carat weight combined with excellent symmetry makes it ideal for solitaire rings, halo settings, or bespoke designs where the cutter’s work will be immediately visible, The Natural Gemstone Company backs the gem’s description and provenance from Brazil, and we welcome inquiries about setting suggestions, custom mounting options, and any further details about the stone’s cutting proportions and care.
