10.08 Ct. Bluish Green Prasiolite from Brazil

This 10.08 carat bluish green prasiolite presents a refined combination of size, color, and cut, attributes that together produce a gem of notable presence and clarity, The oval shape measures 15.09 x 12.70 x 9.30 mm, the cutting style is faceted with a mixed brilliant cut designed to balance table and pavilion reflections, the clarity is graded eye clean when examined at normal viewing distance, the color intensity is described as intense which communicates a saturated and evenly distributed bluish green, the polish is excellent, and the gem has been heat and color enhanced by irradiation, a standard and stable treatment for prasiolite derived from Brazilian quartz. The material is sourced from Brazil, a well recognized locality for fine prasiolite, and documented provenance is available upon request from The Natural Gemstone Company. These objective specifications provide a clear foundation for understanding the gem as both a collector specimen and a wearable jewel, with the mixed brilliant geometry optimized to present depth and scintillation while preserving the stone s natural color character.

Under magnification this prasiolite reveals an internal landscape of inclusions that are both diagnostic and aesthetically compelling, the most prominent features include slender, hairlike needles that run in subtle oriented arrays, tiny pinpoint crystals that catch light and create minute flashes, and delicate wispy veils that form a three dimensional network within the body of the stone. The needlelike inclusions are fine and often aligned with growth directions, a pattern that is consistent with natural quartz formation and that provides a textural contrast to the otherwise transparent crystal. The pinpoint crystals, while too small to affect the eye clean grade at normal viewing distance, contribute discrete points of reflectivity that enliven facet junctions when the stone is tilted. The wispy veils impart a softening effect in certain viewing angles, producing a gentle depth and a slightly velvety backdrop to the more brilliant facet reflections. Together these inclusion types create an unmistakable internal signature, a unique fingerprint that is visible under loupe or microscope and useful for identification and verification.

The character and arrangement of these inclusions influence the gem s visual behavior in ways that are subtle but meaningful, the mixed brilliant cut interacts with the inclusion planes to produce a layered interplay between surface facet flashes and internal texture, facets near the table emphasize the stone s overall color and clarity, while pavilion facets refract light through the inclusion planes, generating faint internal scintillation and an impression of depth. Because the prasiolite is eye clean, these inclusion features remain an element of discovery for a careful viewer or a trained gemologist, revealing themselves under magnification as evidence of natural origin and individual history. The inclusion pattern also aids in distinguishing this piece from synthetic or assembled material, as the orientation, morphology, and distribution of needles and pinpoint crystals align with natural growth conditions typical of Brazilian quartz, making the internal features a reliable signature for provenance and for internal record keeping by The Natural Gemstone Company.

Practical considerations for use and care follow directly from the gem s properties and treatment history, irradiation provides long term color stability for prasiolite but exposure to elevated temperature can modify the color and should be avoided during jewelry repair or manufacturing. Routine cleaning is best accomplished with warm water, a mild detergent, and a soft cloth or brush, aggressive cleaning methods such as steam or ultrasonic should be used only with caution and after consultation with a qualified gem technician. The stone s durability for everyday wear is appropriate when set in a protective mount, and the oval shape and mixed brilliant cut respond well to bezel or prong settings that protect the girdle and reduce the likelihood of impact. For collectors and designers seeking a gemstone with a clear natural signature, consistent provenance from Brazil, and technical specifications documented by The Natural Gemstone Company, this 10.08 carat bluish green prasiolite offers a balanced combination of transparency, internal character, and finished workmanship, each element contributing to a gem that can be reliably identified, responsibly used, and confidently enjoyed.
