7.44 Ct. Bluish Green Prasiolite from Brazil

This listing describes a transparent bluish green prasiolite weighing 7.44 carats, presented in a classic round shape with dimensions 12.82 x 12.78 x 8.55 mm. The stone is faceted in a mixed brilliant cut, combining a faceted crown and pavillion arrangement designed to optimize both light return and scintillation. Color is intense, exhibiting a saturated bluish green that remains stable across viewing angles, and polish is graded excellent, delivering crisp facet junctions and a smooth reflective surface. Clarity has been evaluated as eye clean at normal viewing distance, indicating no inclusions are visible to the unaided eye, and the overall finish and proportions support strong visual performance in a variety of settings. The prasiolite has been irradiated to achieve and stabilize its color, a common and accepted enhancement practice for this material, and provenance is Brazil, a well known source for prasiolite. The Natural Gemstone Company provides this gem with full specification disclosure, and the documented measurements and grade assessments reflect our standard gemological procedures.

Although this specimen is eye clean, natural prasiolite frequently contains microscopic internal features that are evident under magnification and in gemological imaging, and these inclusions serve as unique identifiers that add to the stone character. Typical internal features may include fine growth zoning, minute mineral particulates, minute healed fissures, and subtle clouds, each arranging in patterns that are effectively a natural fingerprint for the specimen. These features are useful for confirming natural origin and tracking provenance when combined with treatment disclosure, and they offer reassurance against synthetic or assembled alternatives. The irradiation treatment affects color, not the fundamental internal structure, and the microscopic characteristics remain consistent with natural formation in Brazilian pegmatitic or hydrothermal environments. For practical use, the stone dimensions and mixed brilliant cut make it well suited as a center gem in rings or pendants, where the intense color and polished facets can be appreciated, and routine care should avoid extreme heat and harsh chemicals to preserve polish and mounted integrity.
