5.91 Ct. Bluish Green Prasiolite from Brazil

This specimen is a transparent bluish green prasiolite weighing 5.91 carats, presented in a round shape with precise dimensions of 11.68 x 11.51 x 8.12 mm. The stone is faceted with a mixed brilliant cut, combining the depth and color capture of step facets with the scintillation and fire typical of brilliant facets, producing a balanced interplay of color and light. Clarity has been evaluated at eye level and graded as eye clean, indicating the absence of inclusions visible to the unaided eye, which contributes to a clear and undisturbed visual field. Color intensity is described as intense, delivering a vivid bluish green saturation that remains consistent across the face up view. The polish is excellent, providing a smooth facet finish that enhances light return and overall visual appeal. The gemstone has been enhanced by irradiation, a stable and commonly used treatment to develop the green hue, and its geographic origin is Brazil, a region known for producing prasiolite of notable color and clarity. These specifications are documented to ensure transparency in attributes and treatments, and The Natural Gemstone Company includes this information to support informed selection and appraisal.

Visually, the prasiolite offers a versatile aesthetic that adapts to both casual and formal contexts, making it suitable for a broad range of jewelry applications. At 5.91 carats and with a diameter just under 12 millimeters, the stone presents a substantial yet wearable presence for center stone settings in rings, pendants, or statement earrings. The mixed brilliant cut enhances brilliance and scintillation when set in open prong settings, while the stable color saturation of the bluish green tone allows it to pair effectively with accent diamonds or colored gemstones for evening wear. For daytime or casual settings, the same properties provide a lively focal point that complements minimalist designs in silver or white gold, while warmer metal choices such as yellow gold or rose gold emphasize the green tones for a more classic look. The balanced combination of facet geometry and excellent polish ensures consistent performance under varied lighting conditions, from soft interior lighting to direct daylight, supporting its use in pieces intended for frequent wear as well as occasional, formal use.

Provenance, treatment, and care considerations are presented plainly to support long term enjoyment and responsible ownership. The irradiation enhancement used to intensify the green hue is stable under normal wear and household lighting, however prolonged exposure to intense heat or harsh chemicals should be avoided to preserve color saturation and surface integrity. The quartz family hardness typically supports regular wear, yet prudent design choices and secure settings help minimize risk of mechanical damage during daily activities. Storage separate from harder stones that could abrade the surface is recommended, along with routine cleaning using mild soap and water and a soft brush, avoiding extreme temperature changes and aggressive cleaning methods. The Natural Gemstone Company provides documentation of origin and enhancement for this piece and can assist with gemological information, mounting recommendations, and bespoke design options to suit either casual or formal applications. Our approach emphasizes clarity in specification and condition, allowing the inherent qualities of this bluish green prasiolite to be considered and appreciated within a range of design contexts.
