5.83 Ct. Green Prasiolite from Brazil

When you are searching for a stone that closes the loop between beauty and conscience, this green prasiolite from The Natural Gemstone Company answers that need. This is a transparent 5.83 carat oval prasiolite, measuring 13.33 by 10.99 by 7.05 mm, faceted with a mixed brilliant cutting style that creates lively scintillation and depth. Its clarity is described as very very slightly included when viewed at eye level, which means that the stone looks clean and bright to the wearer while retaining natural character. The green displays a medium color intensity that reads as fresh and verdant in natural light, and the polish is excellent, allowing facets to catch light and return it as appealing fire and brilliance. This gem has been heat treated to achieve and stabilize its inviting green hue, and its origin is Brazil, a region celebrated for quality prasiolites and a long history of gemstone craftsmanship. If you are seeking an engagement gem that is slightly unexpected yet timeless, a statement ring stone for a meaningful anniversary, or a collector piece that balances color and clarity with ethical consideration, this prasiolite fits the brief with poise.

For the conscious buyer, provenance matters as much as proportions, and we at The Natural Gemstone Company make responsible sourcing a priority. This prasiolite comes to you through vetted channels in Brazil, from partners who operate with respect for local communities and who follow practices that aim to limit environmental impact. We disclose treatments openly, so you can make an informed decision knowing the stone was heat treated to enhance its green color, and that treatment is stable and industry accepted. Beyond treatment disclosure, our sourcing approach emphasizes transparency, traceability and fair dealing with miners and cutters, so that your purchase supports sustainable livelihoods and reduces incentives for harmful extraction methods. As collectors and jewelry designers increasingly prefer gems that align with their values, owning a gemstone that is both beautiful and ethically sourced becomes a meaningful statement. This prasiolite provides that opportunity, combining aesthetic appeal with the comfort of responsible supply chain practices.

From a design perspective, the oval silhouette and mixed brilliant faceting make this prasiolite exceptionally versatile. The oval shape visually lengthens the finger when set in a ring, and at 5.83 carats the stone commands presence without overwhelming delicate settings. The mixed brilliant cut optimizes light return through a combination of pavilion and crown faceting, so the gem appears lively and bright in a variety of lighting conditions, from sunlight to candlelight. The medium green tone sits comfortably between pastel and deep forest shades, which means it complements both warm and cool metals, and pairs gracefully with diamonds or colored side stones. The clarity being very very slightly included at eye level means you have a gem that looks remarkably clean to the naked eye, while preserving the natural inclusions that assure authenticity. The excellent polish strengthens facet definition and overall sparkle, making this stone ideal for a custom engagement ring, a chic pendant, or a museum quality collector setting. Given its dimensions of 13.33 by 10.99 by 7.05 mm, the stone will allow a skilled jeweler room to craft protective yet elegant settings that highlight its oval form and display its green color to best advantage.

Choosing this prasiolite for your collection or as the central stone in a bespoke piece ensures that you are closing a transaction with care, clarity and confidence.
