10.26 Ct. Mint Green Prasiolite from Brazil

This prasiolite is a transparent mint green oval weighing 10.26 carats, with precise dimensions of 16.25 x 11.82 x 8.14 mm. The stone has been faceted in a mixed brilliant cut, combining optimal light return from brilliant facets with table and pavilion geometry that enhances depth and color. The clarity is graded as very very slightly included, evaluated at eye level, and the piece exhibits light color intensity with an excellent polish that maintains crisp facet junctions and mirror like surfaces. The gemstone was heat treated to achieve and stabilize the mint green tone, and the material is sourced from Brazil. These measured attributes are provided by The Natural Gemstone Company to assist in objective evaluation for mounting, design, and long term wear.

Durability begins with the material class, and prasiolite is a variety of quartz, which registers at approximately 7 on the Mohs hardness scale. This hardness gives prasiolite a reliable resistance to everyday scratching from common materials and makes it suitable for most types of jewelry intended for regular use. Quartz has no true cleavage planes, and it typically exhibits conchoidal fracture, which translates to predictable behavior under impact and a lower tendency to split along internal planes. The heat treatment applied to this prasiolite is a standard, stable enhancement for quartz that does not materially reduce hardness or structural integrity. Taken together, these factors mean the gem is well suited to daily wear when set and cared for appropriately.

For practical jewelry application the oval shape and the 16.25 x 11.82 mm face size create a substantial presence that benefits from secure and protective mounting. Bezel settings provide continuous metal protection around the girdle and are particularly effective for rings, bracelets, and pieces subject to frequent contact. Where an open setting is preferred, consider multi prong arrangements with robust prong profiles and sufficient seat engagement to prevent lateral movement. Low profile settings reduce the risk of catching on fabrics and minimize leverage on the stone in impact events. The mixed brilliant cut and excellent polish contribute to lively brilliance and dispersion, which pair well with a range of metals, including yellow gold, rose gold, white gold, and platinum. Because the piece is eye clean aside from very very slight inclusions, the visual effect in larger statement settings will be uninterrupted and appealing.

Maintenance guidance supports sustained durability and appearance for everyday use. Routine cleaning with warm water, a mild detergent, and a soft bristled brush will safely remove accumulated oils and particulate matter without affecting the heat treatment. Rinse thoroughly and dry with a soft, lint free cloth. Ultrasonic cleaning is generally acceptable for intact quartz material, however caution is advised if inclusions are visible at or near the surface, as mechanical shock can propagate existing features. Avoid exposure to strong acids, alkaline cleaners, household bleach, and prolonged contact with chlorinated water, since these environments may affect metal mounts or surface treatments rather than the quartz itself. Sudden and extreme temperature changes should be avoided to reduce any risk of thermal shock to the mount and adhesive components in some jewelry constructions. Regular inspection of the setting by a professional jeweler will help ensure prongs and bezels remain secure and that the stone continues to sit properly in its seat.

In summary this 10.26 carat mint green prasiolite from Brazil combines material hardness, lack of true cleavage, and a stable heat enhancement to provide a gem that is practical for daily wear when appropriately mounted and maintained. The mixed brilliant faceting and excellent polish maximize visual performance, while the oval dimensions make the stone well suited to rings, pendants, and bracelets where protection and secure setting design are incorporated. For designers and consumers seeking a durable, attractive mint green transparent gemstone, this prasiolite offers a balance of resilience and refined appearance. The Natural Gemstone Company provides these technical details to assist in an informed selection and to guide care and setting choices for long term enjoyment.
