10.85 Ct. Bluish Green Prasiolite from Brazil

This transparent bluish green prasiolite weighs 10.85 carats, presenting a substantial and collectible size for green quartz, and it measures 15.71 x 13.10 x 8.59 mm, a generous oval profile that is ideal as a showpiece center stone. The cutting style is faceted with a mixed brilliant cut that optimizes light performance, delivering lively return and scintillation across the table and crown. Clarity is graded as very, very slightly included as evaluated at eye level, indicating an eye clean appearance with only minute inclusions apparent under magnification, and the gem exhibits a light color intensity that reads as a delicate bluish green, an elegant hue that reads both modern and classic. The polish is excellent, contributing to clean facet junctions and crisp facet reflections, and the piece has been heat treated as an enhancement, a common and stable treatment for prasiolite that yields a consistent and desirable green tone. Origin is Brazil, an important provenance for collectors and connoisseurs, where high quality quartz varieties are responsibly sourced and well understood by trade professionals.

From a connoisseur perspective, the 10.85 carat weight alone elevates this prasiolite into a premium category, because stones of this size that combine transparency, fine cut, and a high clarity grade are less common and therefore command attention. The mixed brilliant cut is a deliberate choice to balance depth and spread, increasing apparent size face up while maintaining strong brilliance and fire, and the excellent polish ensures that light is not hindered by surface irregularities. The combination of very, very slightly included clarity and transparent material means the gem will display its bluish green tone uniformly, without cloudiness or distracting features, making it highly suitable for a statement ring, dramatic pendant, or a focused addition to a collection. Heat treatment is a recognized enhancement for prasiolite, performed to achieve stable, attractive color, and when disclosed it supports confident valuation. With provenance from Brazil and presentation by The Natural Gemstone Company, this prasiolite is offered with practical information and gemological confidence that appeals to educated buyers seeking both aesthetic beauty and enduring value.
