11.19 Ct. Yellowish Green Prasiolite from Brazil

This offering from The Natural Gemstone Company is a transparent prasiolite, 11.19 carat, princess shape, with dimensions 12.78 by 12.55 by 10.10 mm. The stone displays a yellowish green hue with intense color intensity, and it has been evaluated as eye clean at normal viewing distance. The princess cut presents precise symmetry and crisp pavilion facets, producing an even distribution of color and controlled light return across the table. The finish is an excellent polish, which enhances surface luster and allows the stone to communicate its clarity and tone without distraction. The material has been heat treated, a standard and stable enhancement for prasiolite that refines and sets the green tone, and the piece is sourced from Brazil, a recognized origin for fine quartz varieties.

From a gemological and practical perspective, this prasiolite balances aesthetic presence with functional durability. Quartz registers 7 on the Mohs hardness scale, providing reasonable resistance to scratches in everyday settings, while the princess cut requires thoughtful mounting to protect the corners. The substantial dimensions and the 11.19 carat weight give this stone an authoritative presence that reads well in both statement rings and bespoke pendants. The stone is suitable for settings in yellow gold, rose gold, white gold, or platinum, each metal offering a different visual context for the yellowish green tone. For pieces intended for frequent wear, a bezel or protective gallery is recommended to shield the corners while retaining the gem as the focal point. For more formal wear, open prong mountings will emphasize brilliance and allow maximum light interaction.

When considered as a generational heirloom, this prasiolite offers a number of enduring attributes. The combination of substantial carat weight, a classic princess silhouette, intense and even coloration, and eye clean clarity is uncommon in green quartz at this size, creating a rarity profile worth preserving. Heat treatment is disclosed and permanent, and the material stability under normal wear means the color will not unexpectedly fade with time under ordinary conditions. Provenance from Brazil and documentation provided by The Natural Gemstone Company will aid in maintaining the gem s authenticity for future custodians. An heirloom is most successful when accompanied by care instructions, a setting chosen for both style and protection, and documentation of origin and treatment. A custom mounting that combines visual restraint with secure protection will make the piece adaptable to changing fashions, ensuring that descendants can wear the gem with confidence across generations.

Long term stewardship protocols will preserve both beauty and value, and practical measures are straightforward. Routine inspection of the setting by a qualified jeweler will prevent loss and address wear to claws or bezel edges, and professional cleaning and light polishing as needed will maintain surface luster without risking the integrity of the stone. Cleaning with mild soap and warm water and a soft brush is appropriate, and prolonged exposure to extreme heat or harsh chemicals should be avoided. The Natural Gemstone Company can supply detailed documentation of the stone s specifications, treatment history, and origin, and we can assist with recommendations for secure settings and independent appraisal for insurance purposes. With proper mounting, routine maintenance, and provenance documentation, this 11.19 carat Brazilian prasiolite will transition from a distinctive contemporary jewel to a well preserved family heirloom, capable of carrying personal history and aesthetic appeal across generations.
