5.65 Ct. Yellowish Green Prasiolite from Brazil

This transparent 5.65 carat round prasiolite measures 11.50 by 11.59 by 8.39 millimeters, and it is faceted in a mixed brilliant cut that combines a brilliant crown with a modified pavilion to maximize both scintillation and color saturation. The cutter has used a medium sized table and carefully proportioned crown and pavilion angles to promote efficient internal light return, creating a balance between broad flashes of light and strong pinpoint scintillation. The clarity grade is eye clean evaluated at eye level, which permits unimpeded pathways for light to travel through the stone, enhancing contrast between bright and dark facets. The light color intensity presents as a delicate yellowish green, and the mixed brilliant topology is calibrated to concentrate color near the pavilion while allowing the crown facets to modulate tone under varying illumination. Excellent polish reduces surface scattering, increasing specular reflection from facet planes and sharpening facet junctions so that windowing is minimized and overall brilliance is preserved.

From a craftsmanship perspective this prasiolite benefits from precise facet symmetry and tight facet junctions, qualities that are evident in the regularity of the star and kite facets across the crown, and the consistent pavilion facet sizing that supports strong total internal reflection. The gem has undergone controlled heat treatment to achieve its stable yellowish green hue, a standard enhancement for prasiolite from Brazilian material, and the process has been executed to avoid over saturation or diffusion that can compromise optical performance. At 5.65 carat the stone provides a substantial face up size suitable for center stones in rings or pendants, the round outline offering predictable light behavior in a variety of settings. The Natural Gemstone Company presents this piece as an example of technical lapidary control, where proportion, facet design, and finishing converge to amplify the inherent optical properties of prasiolite, delivering a transparent, lively gem with crisp facet definition and consistent color presentation.
