11.91 Ct. Prasiolite from Madagascar

This exceptional transparent 11.91 carat cushion shape green prasiolite from The Natural Gemstone Company measures 15.47 x 13.94 x 10.00 mm, and it displays a refined mixed brilliant cut that has been executed to emphasize both depth of color and scintillation. The gem is graded as very very slightly included as evaluated at eye level, and this clarity is consistent with high quality collector stones, offering clean appearance to the unaided eye while preserving natural character under magnification. The medium intense color intensity is a particularly attractive green, showing balanced saturation that reads vivid in daylight yet remains wearable for everyday jewelry. The polish is excellent, which together with the mixed brilliant pavilion yields strong light return and a lively play of facets across the cushion outline. This prasiolite has been heat treated, a stable and widely accepted enhancement for green quartz varieties, and its documented origin in Madagascar adds provenance, as Madagascar has become known for producing well colored quartz material with attractive clarity and size.

For the educated buyer this prasiolite offers clear points of value and historical resonance, making it suitable both as an investment caliber specimen and as the centerpiece for bespoke jewelry. Prasiolite is the commercial name for green quartz most often produced by controlled heat treatment of select crystals, a process that has been practiced for decades to reveal pleasing green tones that mimic the look of naturally green silicates without altering structural stability. The very very slightly included clarity grade and excellent polish enhance durability in settings, and the generous 11.91 carat weight with cushion proportions is ideal for rings, pendants, and museum style mounts that reference antique jewelry traditions. Green stones have long been associated with renewal, prosperity, and protective amulets in multiple cultures, and prasiolite in particular has been used in contemporary and historical inspired pieces as an accessible alternative to emerald and other green gems, allowing designers to evoke classical motifs while offering superior transparency and resistance to wear. When selecting this Madagascar prasiolite from The Natural Gemstone Company the buyer acquires a well documented, attractively cut, and responsibly treated gem that bridges traditional gem heritage and modern gemological standards, ready to become a distinguished focal point in high quality jewelry.
