7.46 Ct. Yellowish Green Prasiolite from Brazil

This is a beautifully transparent 7.46 carat princess shape yellowish green prasiolite, with dimensions of 10.72 x 10.28 x 10.10 millimeters, faceted in a classic princess cut and finished with an excellent polish, presented by The Natural Gemstone Company. The gem displays a light color intensity that reads as a fresh, spring green with a subtle yellow tone, a balance that makes it both wearable and distinctive. This stone has been heat treated, which is the standard enhancement process for prasiolite, and originates from Brazil, a region known for producing clean, well colored quartz specimens. The clarity has been evaluated as very slightly included at eye level, meaning that while tiny inclusions are present, they are minimal and do not interfere with the gem when viewed in typical jewelry use, especially given the disciplined cutting and excellent polish that maximize transparency and brilliance.

From a gemological perspective this prasiolite is a member of the quartz family, with the familiar resilience and stable optical properties that collectors and jewelers value. Quartz typically shows a refractive index around 1.544 to 1.553, and a hardness of 7 on the Mohs scale, which makes this stone suitable for most types of jewelry when set with appropriate protective design considerations. The princess cut has been chosen to emphasize a balance between depth of color and light return, with straight pavilion facets that create lively scintillation and crisp geometric flash, and a broad table that allows the eye to appreciate the stone in a single glance. The excellent polish on this piece ensures that light passes cleanly through the gem, reducing surface diffusion and allowing internal features to contribute to the overall visual character rather than distract from it. The heat treatment used to produce the prasiolite color is a stable, widely accepted enhancement, and sourcing from Brazil gives additional provenance value, since Brazilian prasiolites are recognized for their attractive tone and consistency.

What makes this particular prasiolite unmistakable is its internal signature of inclusions, which give the stone personality and a reliable marker of natural origin for an educated buyer. Under magnification and to careful naked eye inspection the gem shows delicate growth zoning that forms soft, parallel banding, tiny pinpoint and minute crystal inclusions that catch the light as tiny sparks, and slender, hair like internal lines that create a silky shimmer when the stone is tilted. There are also subtle healed fissures that reflect light in a way that adds depth rather than cloudiness, and in some lighting conditions faint, three phase type pockets contribute micro flashes and a sense of internal relief. These features are not flaws in the cosmetic sense, they are natural records of the crystal growth history, and they serve as the gem equivalent of a fingerprint, ensuring that each viewing experience is unique. For the collector who values authenticity and character, these inclusions enhance desirability, because they confirm the natural origin and thermal history that create prasiolite, and they interact with the geometric precision of the princess cut to produce a dynamic interplay of brightness and green tone.

For practical considerations this gem will make a striking center for a ring, pendant, or statement piece, particularly when set to allow light to enter from multiple angles so that its internal textures are showcased. Given the light tone and excellent transparency, complementary metals in warm white gold or yellow gold will emphasize the yellowish green hue, while a bezel with protective edges will help safeguard the corners if used in daily wear.
