5.75 Ct. Bluish Green Prasiolite from Brazil

This radiant 5.75 carat oval bluish green prasiolite measures 12.64 x 10.57 x 7.67 mm, presenting a transparent, highly saturated body color that reads as intense under standard lighting. Cut in a faceted mixed brilliant style, the crown employs a brilliant facet array to maximize scintillation, while the pavilion uses step influenced facets to enhance light return and provide a balanced play between sparkle and color depth. The mixed brilliant configuration preserves table transparency for color appreciation, and the facet junctions and symmetry demonstrate precision cutting, yielding an excellent polish and crisp facet edges. Clarity is graded eye clean at normal observation distance, allowing the stone to present an uninterrupted visual plane and an open window to its saturated bluish green tone. This specimen is irradiated to achieve and stabilize its prasiolite hue, and its geological origin is Brazil, a source known for gem quality prasiolite with consistent crystal structure and favorable cleavage properties for precision cutting.

From a gemological and practical perspective this prasiolite combines optical performance and wearability, making it suitable for ring, pendant, or bespoke signed pieces designed by collectors and designers. Quartz family hardness near 7 provides robust resistance to everyday abrasion when properly set, and the excellent polish will maintain strong light return over years of wear. The irradiation enhancement performed is a stable, industry accepted treatment that produces enduring color when the stone is cared for correctly. To preserve maximum vibrancy avoid prolonged exposure to extreme heat or harsh chemicals, and choose protective settings that reduce risk of sharp knocks to the girdle or table. When mounted with attention to metrology and protection, its intense bluish green saturation and the interplay between its brilliant crown and stepped pavilion will continue to captivate, projecting lively scintillation and depth of color even as styles evolve. For collectors and clients seeking both technical excellence and timeless appeal, The Natural Gemstone Company certifies this prasiolite for its cut, clarity, color, and origin, offering a gem that will remain a focal point in fine jewelry for years to come.
