13.84 Ct. Bluish Green Prasiolite from Madagascar

This exceptional bluish green prasiolite weighs 13.84 carats, an uncommon size for this gem species, and its weight is the single most important factor that elevates its rarity and value. Larger prasiolites are rarely found transparent and eye clean, and a stone of this caliber commands attention because weight in carats does not simply add physical size, it increases desirability and per carat value disproportionately compared to smaller examples. Faceted in an emerald cut, this gem measures 15.95 by 12.77 by 9.82 millimeters, offering an expansive table and elegant step facets that emphasize depth of color and clarity. Where many market alternatives present as small, pale, or heavily included stones, this piece stands apart with vivid color intensity and a clarity grade described as very very slightly included evaluated at eye level, which for a prasiolite of this size is exceptionally rare and collectible.

The cut quality and excellent polish further distinguish this prasiolite from mass market offerings. Many competitors sell heat treated material without full disclosure, and many commercial stones are cut to yield weight rather than optical performance. This prasiolite has been heat treated as disclosed, and the treatment enhances a naturally appealing bluish green hue while preserving transparency and minimizing visible inclusions. Origin from Madagascar adds provenance, as material from this source often yields superior crystal quality compared to many global finds. When compared to similar colored gems on the market, this 13.84 carat emerald cut prasiolite offers superior presence, cleaner clarity, and a more vivid tone, making it ideal for a high impact solitaire ring, an elegant pendant, or a collector seeking standout pieces. At The Natural Gemstone Company we prioritize stones that combine size, color, clarity, and cut, and this specimen reflects that commitment to quality and value. For a buyer seeking a rare, substantial prasiolite that will perform both as jewelry and as a collectible asset, this gem outperforms typical market choices in exclusivity, visual appeal, and long term desirability.
