6.19 Ct. Bluish Green Prasiolite from Brazil

This prasiolite is a remarkable example of what careful cutting and thoughtful treatment can achieve. We present a transparent, bluish green round prasiolite weighing 6.19 carats, with precise dimensions of 12.31 x 12.17 x 7.66 mm. The stone is faceted and fashioned in a mixed brilliant cut, a choice that optimizes the gem for both fire and brilliance. In a mixed brilliant cut the crown facets are arranged to act like a full brilliant, while the pavilion is modified to balance light return and scintillation, producing lively flashes across the table and crown. The excellent polish amplifies the surface luster and allows each facet junction to act as a crisp mirror, making this piece a natural centerpiece in any fine jewelry collection. At this size and with such a well executed cut, the stone commands attention on its own, and also performs superbly when mounted as a solitaire or as the focal point in a halo or three stone setting.

From a grading perspective this prasiolite exhibits attributes that educated buyers prize. The color intensity is described as intense, with a richly saturated bluish green tone that is both vibrant and elegant. The clarity is eye clean, evaluated at eye level, which means no inclusions are visible to the unaided eye under normal viewing conditions. This is a meaningful distinction because prasiolite often carries minor inclusions that can affect brilliance and transparency, yet this specimen maintains a clear window through the table and crown. The combination of intense color and eye clean clarity at a weight of over six carats is uncommon in the market for green quartz, making this an attractive option for collectors and those seeking substantial gemstones in wearable sizes. The stone has been enhanced by irradiation, a stable and industry accepted treatment used to achieve and stabilize the green hue in quartz. Irradiation is a common and predictable enhancement for prasiolite, and when disclosed clearly as we do here, it provides buyers with the full information needed to assess value and suitability for their intended use.

Origin matters in both aesthetic character and market perception, and this prasiolite originates from Brazil, a source known for producing high quality quartz varieties with clean crystal habits and attractive color. Brazilian prasiolite often presents with uniform color saturation and good crystal clarity, which in this instance has allowed lapidary work to achieve symmetry and facet alignment that support superior light performance. For the educated buyer, the provenance combined with documented enhancement status and the measurable attributes such as carat, dimensions, cut style, clarity grade, and polish provide a comprehensive basis for evaluation. The Natural Gemstone Company adheres to transparent disclosure practices and quality control, ensuring that this gemstone is described accurately and that its aesthetic and physical attributes are verified before offering it to clients. We encourage buyers to request a photographic record and, if desired, an independent gemological report from a reputable laboratory to further substantiate the evaluation.

As a salesperson and gem specialist I can say that this prasiolite is well suited to become the centerpiece of a refined jewelry commission or the highlight of a carefully curated collection. Its combination of size, intense color, eye clean clarity at eye level, mixed brilliant cutting style, and excellent polish creates a balance of optical performance and wearable practicality. The stability of irradiation treatment means the color will remain consistent under normal wear conditions, and routine care for quartz should be sufficient to preserve its beauty. For mounting I recommend settings that showcase the table and crown, such as bezel with a thin rim to protect the girdle, or a classic prong solitaire to maximize light entry. The Natural Gemstone Company stands behind the gem with full disclosure and professional handling, and our team is available to advise on certification options, custom setting designs, and secure shipping. This prasiolite represents both a visually striking selection and an informed purchase for buyers who appreciate the confluence of gemological merit and artisanal cutting excellence.
