12.66 Ct. Green Prasiolite from Brazil

This exquisite transparent 12.66 carat prasiolite presents in an asscher octagon shape, with precise dimensions 14.14 x 13.20 x 10.34 mm, and a faceted asscher cut that emphasizes clarity and structural brilliance. The cutting style follows classic step facet geometry, providing a bold, architectural play of light that complements the stone size and proportions. Clarity is graded as very very slightly included evaluated at eye level, which for an educated buyer means the inclusions are minimal and do not detract from the visual purity or the gem's faceting performance. The color intensity is recorded as intense, a rich bold green that remains consistent across the face of the stone, and the polish has been completed to an excellent standard which maximizes light return and surface luster. The enhancement is irradiated, a widely accepted and permanent treatment for prasiolite, and the origin is Brazil, a region known for producing high quality quartz varieties with excellent color saturation and stable crystal structures.

Beyond technical specifications, the deep, saturated green of this prasiolite reads as a refined statement of personal power and distinction, making the gem ideal for a signature ring or a singular pendant that commands attention with quiet authority. For the discerning buyer, the combination of substantial carat weight, VVS level clarity at eye level, intense uniform color, and superior asscher faceting translates into a stone that performs exceptionally both in direct brilliance and in collectible value. The irradiation treatment is disclosed and is considered stable under normal wear, adding predictable color enhancement without compromising structural integrity. Brazil as the provenance adds provenance value, given the consistent sourcing standards and gemological reputation of Brazilian prasiolite. At The Natural Gemstone Company, we present this piece with full disclosure and gemological detail to support informed decisions, offering a gemstone that is as much an investment in personal expression as it is in material quality.
