5.47 Ct. Bluish Green Prasiolite from Brazil

This prasiolite is a transparent, oval shaped gemstone weighing 5.47 carats, with precise dimensions of 12.78 x 10.53 x 7.60 mm. The cutting style is faceted, executed in a mixed brilliant cut that emphasizes both scintillation and color saturation. The hue is a distinctly bluish green, presented with intense color intensity that remains even across the stone when viewed against white and neutral backgrounds. Clarity has been assessed as very very slightly included at eye level, indicating minute internal features that do not compromise transparency or overall visual appeal. The surface finish is of excellent polish, ensuring smooth facet junctions and optimal light return. The stone originates from Brazil, a region recognized for producing high quality prasiolite, and it has undergone an irradiated enhancement to achieve and stabilize its attractive green tones.

The mixed brilliant faceting pattern combines the directional light performance of step elements with the dynamic reflection of brilliant facets, creating a balance between vivid color and lively scintillation. With its transparent body and careful facet placement, this prasiolite displays a prismatic play of light when rotated under direct illumination, and it maintains strong face up color when set in jewelry. The very very slightly included clarity grade means that inclusions are minimal and in most cases not observable without magnification, which supports the stone in delivering a clean visual presentation from typical viewing distances. The excellent polish contributes to uninterrupted light transmission, enhancing both brilliance and the perception of depth within the oval outline. The combination of precise proportions, mixed brilliant cutting, and high polish allows the stone to perform well in a variety of settings, preserving its aesthetic impact while minimizing the risk of light leakage that can mute color.

The enhancement method has been disclosed as irradiated, which is a stable and widely accepted treatment for enhancing the green hues of prasiolite. Under normal wear conditions the color achieved through irradiation remains durable, and standard precautions such as avoiding prolonged exposure to extreme heat and harsh chemicals will further preserve the stone. As a variety of quartz, prasiolite benefits from a hardness consistent with quartz family minerals, which contributes to resistance against everyday abrasion. Routine care consisting of gentle cleaning with warm water and mild soap, followed by drying with a soft cloth, will maintain polish and surface condition. When properly set and cared for, the stone will maintain its integrity, and its intense bluish green color will continue to captivate over the years, reflecting both the original material qualities and the craftsmanship of the cutting and finishing processes.

This example of Brazilian prasiolite is suitable for a range of fine jewelry applications, including rings, pendants, and statement pieces that allow light to interact with its mixed brilliant facets. The generous 5.47 carat weight and substantial oval dimensions make it particularly compatible with designs that highlight the stone as a focal element, while the excellent polish and minimal inclusions support close inspection and regular wear.
