5.84 Ct. Yellowish Green Prasiolite from Brazil

This prasiolite offered by The Natural Gemstone Company is a transparent, round shaped gem weighing 5.84 carat, with precise dimensions of 11.53 by 11.59 by 7.93 millimeters. The cutter selected a faceted mixed brilliant style to marry the depth and color saturation advantages of step influences with the scintillating light return of brilliant facets. The gem exhibits a yellowish green hue with light color intensity, evaluated clarity at very very slightly included at eye level, and an excellent polish that yields crisp facet junctions and mirror like facet planes. Origin is Brazil, and the material has been heat treated to develop and stabilize the prasiolite tone, a common and professionally accepted enhancement for this variety of quartz. These baseline specifications position this stone as a substantial and technically refined example of heat treated prasiolite suitable for a centerpiece ring or pendant.

The mixed brilliant cut in this round prasiolite has been engineered to optimize light performance for quartz class refractive indices. The crown presents a balanced crown angle regime and a table to girdle proportion that maintains a strong face up presence, while the pavilion is cut on the deeper side to increase light travel and color depth. The measured depth is seven point nine three millimeters against an average diameter of eleven point five six millimeters, yielding a depth ratio of approximately sixty eight point six percent, which is intentionally deeper than a thin brilliant to favor internal reflection and color saturation. In practical terms this translates into pronounced scintillation and localized flashes across the table and facets when the gem is viewed in motion. The excellent polish minimizes light leakage from micro abrasions and polish lines, so the facet intersections act as efficient mirrors. The very very slightly included clarity grade at eye level means inclusions are minimal and typically of a character and placement that do not interrupt facet symmetry or hinder the delivery of bright, undistorted flashes.

Color evaluation and enhancement deserve close attention because the yellowish green hue is central to the gem’s appeal. The light color intensity is subtle, tending toward a delicate tea like green that reads differently under various light sources, owing to quartz low pleochroism and clean transparency. Heat treatment is used to convert amethyst or to refine undertones into the prasiolite spectrum, and when executed properly it produces a stable, uniform tone without introducing artificial over saturation. The Brazilian origin contributes to the quality profile, as Brazilian prasiolites often combine good clarity and even crystal structure that respond well to precision cutting. Compared to common alternatives the prasiolite presents a distinct visual signature, it lacks the high dispersion of diamond and the higher refractive index of sapphire or tourmaline, yet its mixed brilliant faceting and exceptional polish create lively facet contrast and a glassy, clean brilliance that is often more immediately wearable than darker green gemstones. Against peridot, which tends to present more olive yellow overtones and can show luster variations due to inclusions, this prasiolite reads as more even and crystalline, particularly in daylight. Compared to green tourmaline or sapphire, which can display richer saturation but also greater material scarcity at this size and clarity, the prasiolite stands out for its clarity to carat weight ratio and face up brightness for its category.

For the technically minded buyer considering setting and care, this prasiolite is well suited to open prong or bezel settings that showcase the mixed brilliant pavilion and allow light into the crown. The large eleven and a half millimeter round face is optimal for solitaire rings where the facet pattern can be appreciated in motion, or for halo designs that emphasize the subtle yellowish green hue against contrasting metals. The heat treated nature of the material is stable under normal wear conditions, however routine high heat exposure should be avoided, and ultrasonic cleaning is generally safe for quartz but should be used with caution if the mounting introduces stress. The Natural Gemstone Company presents this prasiolite as a technically refined offering, combining an expert mixed brilliant cut, very very slightly included clarity at eye level, and excellent polish in a substantial five point eight four carat size. For collectors and designers who value cut strategy, clarity, and controlled color, this gem delivers a rare balance of face up brilliance and even tone, making it a standout selection among green gemstones in this weight class.
