10.19 Ct. Yellowish Green Prasiolite from Brazil

This listing presents a transparent 10.19 carat oval prasiolite, with dimensions 15.34 x 12.95 x 8.93 mm, faceted in a mixed brilliant style, exhibiting a pleasing yellowish green hue. The gem is eye clean when viewed at normal viewing distance, with a medium color intensity and an excellent polish. This prasiolite has been heat treated, a well established and stable enhancement method for quartz that is commonly used to produce and stabilize the green tones associated with prasiolite. The material originates from Brazil, a trusted source for high quality quartz varieties. For an educated buyer the key value indicators here are the combination of significant weight above ten carats, clean clarity at eye level, and a precise mixed brilliant cut that maximizes both table sparkle and pavilion return, all of which are difficult to find together in natural quartz material at this scale. The Natural Gemstone Company provides full disclosure of treatment, precise measurements, and multiple images to support accurate assessment prior to purchase.

The cutting and finish of this stone are particularly relevant to its desirability in finished jewelry. The mixed brilliant cut delivers a balance of scintillation and overall light return, creating lively face up appearance while preserving depth and saturation through the pavilion facets. The oval outline of 15.34 x 12.95 mm offers an elegant spread, making the gem ideally suited to ring centers, pendant stones, and statement earrings, while the 8.93 mm depth retains secure setting proportions for bezel and prong work. Clarity rated as eye clean indicates absence of inclusions that would interrupt light transmission or weaken the stone under normal wear, and the excellent polish enhances facet contrast and reduces surface light leakage. The medium color intensity is visually appealing and versatile, avoiding the overly dark tones that can reduce brilliance, and the heat treatment used to achieve and stabilize the green hue is a standard and accepted practice for producing prasiolite. Provenance from Brazil further supports quality expectations, as Brazilian quartz deposits are known for producing transparent, large, and well formed crystals that respond predictably to controlled heat treatment.

Color and setting choices will strongly influence how this yellowish green prasiolite interacts with skin tones and overall styling, and understanding these interactions helps a buyer make an informed design decision. On fair complexions with cool undertones the yellowish green will read as a bright, fresh accent, and pairing the stone with white metals such as platinum or white gold will emphasize the cooler green aspects, producing a crisp modern look. For customers with warm undertones the yellowing component in the stone complements warm skin, and yellow gold or rose gold settings will harmonize with the stone to create a soft, glowing effect. On olive or medium complexions the hue tends to integrate naturally, appearing almost botanical and flattering when framed in either mixed metal designs or a halo of small diamonds. On deeper skin tones the gem will contrast beautifully, appearing vivid and luminous, and larger carat weight makes a confident center stone for high impact jewelry. Practical setting recommendations include a low profile bezel for everyday wear, or a prong set halo with small white or champagne diamonds to increase visual presence without obscuring the unique green character. Because quartz is a seven on the Mohs scale, the gem is suitable for most jewelry types with sensible care. Clean with warm soapy water and a soft brush, avoid strong acids and prolonged exposure to extreme heat, and consult The Natural Gemstone Company for additional images, bespoke setting advice, and any requests for certification or independent third party reports.
