This prasiolite began as a modest piece of rough in a Brazilian deposit, discovered by experienced field teams familiar with the regional geology. After extraction the rough was catalogued and transported under controlled conditions to preserve clarity and color integrity. Mineralogical assessment identified the material as suitable for heat enhancement, a standard practice for prasiolite to unlock a stable yellowish green tone. The heat treatment was applied with precision, followed by a period of controlled cooling and quality checks. Skilled lapidaries then selected an oval outline to maximize weight retention and optical performance, executing a mixed brilliant faceted design to balance scintillation and light return. Throughout cutting and polishing each facet was measured against strict tolerances, resulting in an excellent polish and a final gem that reflects light with clear, lively brilliance. Final grading was performed at eye level and recorded as very very slightly included, confirming a high degree of transparency for a stone of this size.
The finished gem listed by The Natural Gemstone Company is a transparent 6.49 carat oval shape prasiolite, with dimensions 13.66 by 11.15 by 7.79 millimeters. The cutting style is faceted with a mixed brilliant cut, the clarity is graded as very very slightly included evaluated at eye level, the color presents an intense yellowish green saturation, and the polish is excellent. Enhancement is by controlled heat treatment, and the origin is Brazil. This combination of weight, dimensions, and cutting proportions yields a stone with substantial presence suitable for a prominent solitaire setting or a refined bespoke design. Detailed provenance and treatment information accompanies the gem, ensuring confidence for designers and clients who require transparency about origin and processing. The handling and presentation adhere to professional standards, ensuring the gem arrives ready for mounting or inclusion in private collections, with documentation to support its grade and treatment history.
