5.64 Ct. Yellowish Green Prasiolite from Brazil

This prasiolite is a transparent, round faceted gem weighing 5.64 carat, with dimensions of 11.22 by 11.45 by 7.91 millimeters, originating from Brazil and heat treated to stabilize and enhance its yellowish green hue. The color reads as a yellowish green with medium color intensity, balanced between fresh spring green and a warm yellow undertone, resulting in a lively appearance under a range of lighting conditions. Clarity at eye level is evaluated as very very slightly included, which translates to exceptional apparent cleanliness to the naked eye while preserving natural internal identifiers that are important to collectors and gemologists. The cutting style is faceted with a mixed brilliant configuration, and the surface finish shows an excellent polish that contributes to superior light return and clean facet junctions. The Natural Gemstone Company presents this stone as an example of a well prepared prasiolite specimen that combines natural origin and considered enhancement to achieve both visual appeal and wearability.

The mixed brilliant cut employed in this round prasiolite is a considered compromise between light performance and weight retention, with a faceting scheme that places small brilliant facets on the crown to maximize scintillation, combined with modified pavilion facets that retain material and improve durability. The crown projects a precise star and kite facet arrangement that channels incident light into lively flashes, while the lower girdle and pavilion facets control the balance between broad flash and fine scintillation, producing a dynamic pattern during movement. Symmetry is closely matched across the radial facet rows, which preserves optical symmetry and minimizes light leakage. The table size has been chosen to balance face up color saturation with bright return, avoiding overlarge tables that would flatten the perceived depth of color. Excellent polish has been executed on every facet, resulting in crisp facet planes that enhance contrast and make the stone read cleaner and more saturated under standard gemological lighting.

Inclusions are present but restrained, and they serve as natural fingerprints that individualize this gemstone, confirming its authenticity and origin story while contributing subtle character. Evaluated as very very slightly included at eye level, most of the internal features are microscopic and become readily apparent only under magnification. The inclusion suite in this prasiolite is dominated by minute pinpoint crystals and a few delicate, healed feather structures that register as soft internal planes when viewed at higher magnification. These inclusions do not form a dominant visual distraction, rather they catch and disperse light in micro ways that add to the stone s internal texture and scintillation. Because the inclusions are sparse and shallow, they have minimal impact on durability, and the cutter has oriented the pavilion and crown to sequester any more prominent features away from the primary window to maintain an eye clean appearance from the table. From a gemological perspective these micro inclusions are valuable as provenance markers, since the inclusion morphology and distribution patterns align with expectations for prasiolite of Brazilian origin that has undergone controlled heat treatment.

For practical use and design integration, this 5.64 carat round prasiolite is versatile and well suited to an array of settings that exploit its color and cut, from a halo ring that emphasizes dispersion to a simple solitaire that showcases the stone s transparency and medium color intensity. Because the cutting shape is round and the mixed brilliant faceting creates consistent optical performance across viewing angles, the gem adapts well to both closed back and open back settings, though an open setting will allow the full nuance of the yellowish green color to be appreciated in natural light. Routine care includes avoiding sudden temperature changes and exposure to harsh chemicals, and cleaning with warm soapy water and a soft brush will maintain surface polish and optical performance. The Natural Gemstone Company provides this prasiolite with documented origin and enhancement disclosure, and our detailed imagery and measurements allow designers and connoisseurs to assess the gem accurately prior to setting. Collectors who value technical precision in faceting and authenticity in natural character will find this specimen compelling, as it marries thoughtful lapidary technique with traceable Brazilian provenance and measured enhancement that together yield a durable, attractive, and identifiable prasiolite suitable for fine jewelry and specialized collections.
