4.12 Ct. Green Prasiolite from Madagascar

One beautiful transparent 4.12 carat oval shape green prasiolite is presented by The Natural Gemstone Company, with dimensions of 11.92 x 9.78 x 6.03 mm. This stone is faceted with a mixed brilliant cut that maximizes light return, and it shows a clarity grade of eye clean when evaluated at eye level. The color displays medium intensity, a lively green that balances saturation and brightness, and the polish is excellent, producing crisp facet junctions and a clean table. The material was enhanced by irradiation to achieve and stabilize the green tone, a common and accepted treatment for prasiolite, and the origin is Madagascar, a source known for producing transparent and well colored quartz varieties. The combination of size, clarity, and cut yields a gemstone that reads well in hand, offering both presence and versatility for fine jewelry settings.

In terms of reflective qualities, prasiolite sits within the quartz family and offers a vitreous luster and a glasslike sparkle. Compared with higher refractive index gemstones in the green category, such as tourmaline or green sapphire, this prasiolite will exhibit a softer brilliance and gentler, more even light dispersion. Compared with emerald, which often carries surface reaching inclusions and typically requires clarity enhancements, this prasiolite presents a more transparent appearance with consistent optical performance, and the eye clean grade here enhances perceived value for an educated buyer who prioritizes clarity. The mixed brilliant faceting enhances scintillation and gives lively flashes across the crown, while the excellent polish increases perceived depth and color saturation. For collectors and designers seeking an elegant green stone with reliable stability after irradiation, and with manageable care requirements, this prasiolite offers an excellent balance of color, clarity, and light performance. The Natural Gemstone Company provides this gem with clear disclosure of treatment and origin, supporting informed buying decisions for connoisseurs and professionals who value transparency, gemological integrity, and aesthetic appeal.
