5.68 Ct. Bluish Green Prasiolite from Brazil

This beautiful transparent prasiolite from Brazil presented by The Natural Gemstone Company is a refined collector grade gem that balances size, color, and cutting precision. It weighs 5.68 carats and measures 12.67 by 10.47 by 7.62 millimeters, in a classic oval shape that offers generous face up presence while maintaining comfortable proportions for ring or pendant settings. The cutting style is faceted with a mixed brilliant cut that combines step and brilliant facets to maximize both color saturation and scintillation. Color is described as bluish green with intense color intensity, and the gem has an excellent polish that produces crisp facet reflections and a lively, even surface appearance. The stone has been heat treated, a standard and stable enhancement for prasiolite, and it is graded as eye clean when examined at normal viewing distance, which underscores its suitability for high quality jewelry.

From a gemological perspective prasiolite is a variety of quartz, often produced by controlled heat treatment of amethyst or green quartz, and Brazilian material is particularly respected for even color and good transparency. The intense bluish green hue of this example is a desirable tone that reads well in both white metal and yellow metal settings, and it shows attractive color shift and depth when viewed from different angles due to the mixed brilliant cutting. Clarity grading of eye clean means no inclusions are visible to the unaided eye at normal viewing distance, however like all natural crystals this prasiolite will contain microscopic and sub millimeter inclusions when examined under magnification. These internal features can include tiny mineral crystals, minute fluid inclusions, and healed fissures that record the gem s geological history. For the educated buyer these inclusions function as unique identifiers, a natural fingerprint that helps confirm origin and natural formation, and they add character without compromising visual appeal or durability.

The mixed brilliant cut employed in this oval prasiolite is chosen to balance light return and color saturation. The pavilion and crown facet arrangement is calculated to minimize windowing while enhancing the gem s natural color, and the generous girdle and well centered table produce a pleasing symmetry face up. Excellent polish means that facet junctions are crisp and the surface is free of noticeable abrasions, which improves the stone s ability to display lively flashes of light and strong face up brilliance. The proportions and the 5.68 carat weight provide a substantial presence while remaining versatile for custom rings, three stone settings, or a high quality pendant. Origin from Brazil contributes to its market desirability because several Brazilian localities have long produced quartz material prized for clarity and color, and provenance from a recognized source can enhance confidence in grading and treatment disclosure.

For practical considerations prasiolite is a durable gem for everyday wear with a Mohs scale hardness of seven, making it more scratch resistant than many softer gems but less hard than sapphires and diamonds, so prudent care is recommended. Because this specimen has been heat treated to achieve its bluish green color it is stable under normal wear conditions, however prolonged exposure to high heat and aggressive chemicals should be avoided to preserve color and polish. Cleaning with warm soapy water and a soft brush is recommended, and ultrasonic cleaning is generally acceptable for clean, intact quartz but should be used with caution if the setting places stress on the stone. For rings we recommend protective settings such as bezel or partially bezel mounts for active wearers, and for pendants and earrings prongs with secure seats will showcase the stone s pavilion and allow light to enliven the color. At The Natural Gemstone Company we document the weight, measurements, cut, clarity grade, polish grade, color intensity, enhancement disclosure, and country of origin for each piece, and we are pleased to offer this bluish green prasiolite for collectors and designers who appreciate a natural gemstone with eye clean clarity and exceptional face up color.
