6.33 Ct. Yellowish Green Prasiolite from Brazil

This prasiolite is a precisely executed round faceted gem, weighing 6.33 carats, with measured dimensions of 12.04 x 12.18 x 7.92 mm, a face up presence that reads substantial on the finger or as a center stone in bespoke jewelry. The cutter employed a mixed brilliant configuration, combining a well proportioned brilliant crown with a pavilion faceting scheme that emphasizes contrast and color retention, generating a lively interplay between broad flashes and fine scintillation. The table and crown facet relationships produce a balanced light return, the depth at approximately sixty five percent being optimal for preserving both brilliance and color saturation in a gem of this diameter. The finish is executed to an excellent polish standard, the facet junctions showing crisp beveling and consistent symmetry, which contributes to a clean, crisp contrast pattern visible from multiple viewing angles.

Color evaluation places the piece in the medium intensity range, exhibiting a yellowish green hue that is evenly distributed across the stone, with no perceptible zoning to the unaided eye. Clarity is graded as eye clean at normal viewing distance, the material showing no inclusions that interrupt the visual field or detract from light performance, which allows the mixed brilliant geometry to produce strong return and lively dispersion. Enhancement disclosure is full and transparent, this prasiolite having been heat treated, a stable and standard practice that refines the hue while maintaining structural integrity. Origin is Brazil, and the material exhibits the characteristic response to light and cutting typically associated with Brazilian quartz derivatives, favoring warmer green tones under neutral illumination. The combination of medium intensity color, careful mixed brilliant faceting, and eye clean clarity results in a gem that reads both lively and refined, suitable for designs that prioritize face up color and dynamic light behavior.

At The Natural Gemstone Company we pair technical rigor with responsible sourcing, maintaining direct relationships with Brazilian suppliers and cutters to ensure traceability and ethical practices throughout the supply chain. Our sourcing protocol includes due diligence on labor conditions, confirmation of compliant environmental practices at the point of extraction, and verification of treatment disclosure prior to acquisition. The heat treatment applied to this gem is disclosed and documented, and we provide provenance notes that describe the chain of custody from mine to cutter to our inventory, offering conscious consumers the level of transparency they expect when choosing a responsibly sourced gemstone. The cutter selection and finishing were managed with an emphasis on minimizing material waste, and cutters were engaged under fair compensation agreements to promote artisanal skill and longevity in the cutting community.

From a practical and design perspective this prasiolite is versatile, robust, and selection ready for a variety of settings, its hardness comparable to quartz lending good wearability when set with appropriate protection. The diameter and depth proportions favor open prong settings to maximize light entry and scintillation, while a low profile bezel can be considered where daily wear and impact resistance take precedence, always considering that bezel settings will marginally reduce apparent brilliance. For settings that celebrate the mixed brilliant cut, designs that allow light to pass through the pavilion will showcase the internal contrast pattern and strengthen visual depth. Care recommendations emphasize gentle handling and avoidance of sudden extreme thermal exposure that could affect hue, routine cleaning with mild soap and warm water, and professional cleaning verification for ultrasonic or steam methods. The Natural Gemstone Company provides additional high resolution imagery and detailed provenance documentation upon request, enabling collectors to evaluate cut proportions, color nuance, and sourcing credentials before purchase, supporting the thoughtful curation of a consciously minded gemstone collection.
