5.61 Ct. Green Prasiolite from Brazil

This listing from The Natural Gemstone Company presents a beautiful transparent green prasiolite weighing 5.61 carat, in a classic round shape with exact dimensions of 11.59 x 11.60 x 7.68 mm, faceted with a mixed brilliant cut that balances scintillation and light dispersion. The stone displays a medium color intensity with a fresh, grassy green hue that is pleasing to the eye and versatile for many jewelry designs. Clarity is graded as eye clean when evaluated at eye level, meaning that no inclusions are visible to normal unaided viewing, which enhances both aesthetic appeal and market desirability. The polish is excellent, giving crisp facet junctions and lively reflections across the crown and pavilion, and the stone has been heat treated to achieve and stabilize its green color, a well accepted practice in the trade. Origin is Brazil, a provenance that brings geological pedigree and supply chain transparency, and that provenance is included with this offering from The Natural Gemstone Company.

Technically minded buyers will appreciate that prasiolite is a green variety of quartz, and that quartz typically has a refractive index around 1.544 to 1.553 and a specific gravity near 2.65, values that contribute to the gem s optical performance and perceived size on the finger. The mixed brilliant cut on this 11.59 x 11.60 x 7.68 mm round has been executed to optimize return of light to the observer, combining a brilliant style crown to enhance sparkle with a modified pavilion to preserve depth and color saturation. The excellent polish and precise facet symmetry reduce light leakage and emphasize the stone s transparency, so an educated buyer will see both an attractive appearance and technically sound cutting practice. Because the clarity is eye clean, this prasiolite reads as bright and uncluttered in jewelry settings, allowing faceted reflections to remain uninterrupted by visible features, which adds to the gem s desirability for collectors and designers alike.

The Brazilian origin of this prasiolite contributes materially to its value and collectible status. Brazil, particularly the states known for pegmatitic and hydrothermal quartz deposits, has long produced large, clean quartz crystals that make high quality prasiolite possible after controlled heat treatment. Provenance from Brazil carries geological credibility, because the country has established mines and supply chains accustomed to producing facet grade material rather than strictly ornamental material. For an educated buyer provenance matters for several reasons, it indicates likely trace element and inclusion patterns that influence durability and color, it supports reasonable expectations of ethical mining and supply documentation, and it affects secondary market perception. Large, eye clean prasiolites of this size are less common in many localities, so a 5.61 carat round from Brazil, with excellent polish and a pleasing medium green, occupies a stronger position in the market than comparable stones from less reputable sources.

From a practical perspective this prasiolite offers both beauty and sensible wearability, and The Natural Gemstone Company is prepared to advise on settings that will protect and showcase the stone. With a Mohs hardness of about 7 quartz is durable enough for everyday jewelry when set thoughtfully, and we recommend protective settings such as a bezel or a secure prong mount for rings that will receive frequent wear, while a pendant or earrings are excellent choices to maximize longevity. Heat treated prasiolite is generally stable under ordinary care, however prolonged exposure to high temperatures or aggressive chemicals should be avoided, and steam cleaning is not recommended. Warm soapy water and a soft brush provide safe and effective cleaning. We provide high resolution images, measured dimensions, and full disclosure of treatments, and The Natural Gemstone Company can supply additional documentation or assistance with custom settings to help you integrate this 5.61 carat green prasiolite into a piece that meets both aesthetic and investment criteria. This stone represents a thoughtful purchase for collectors and clients seeking a transparent, well cut, and well sourced green quartz with both visual presence and sound gemological pedigree.
