11.75 Ct. Bluish Green Prasiolite from Brazil

From the moment this stone was first glimpsed in the alluvial deposits of Brazil, it began a quiet journey from the earth to the hand. Small pockets of prasiolite form where geology, time, and heat work together, and this particular crystal was discovered in a region known for modest scale mining and a close relationship between miners and the land. Gentle rains and patient excavation revealed a rough nodule that hinted at a delicate bluish green. We sourced this material with care, choosing suppliers who work with local communities, who practice minimal impact extraction, and who respect the rhythms of the terrain. The Natural Gemstone Company follows these stories from the first discovery, and we believe that knowing a gem by its origins makes wearing it more meaningful.

Ethical sourcing is not a slogan for us, it is the framework that shapes every selection. From initial purchase through to cutting and sale, this prasiolite was handled with transparency, and payments were made to ensure fair compensation for the hands who brought it to light. We insist on traceability, and where possible we support projects that reinvest in regional education and environmental restoration, helping to offset the footprint of mining. Your choice to add a stone like this to your collection is a choice for mindful consumption, one that values provenance and respect for people and place. The Natural Gemstone Company documents each step to offer you confidence, because a gem that is beautiful should also sit well with your values.

In the lapidary studio the rough was examined and readied for transformation, and the result is a transparent 11.75 carat oval prasiolite, measuring 17.54 by 12.68 by 8.16 millimeters, cut in a mixed brilliant style that balances scintillation and table brilliance. The cutter worked to preserve weight while coaxing out a light, bluish green tone that is subtle and luminous. The clarity grade is very very slightly included, evaluated at eye level, which means that the stone reads clean to most viewers yet retains natural character when inspected closely. The surface shows an excellent polish, and the facets carry light with a soft, refreshing glow. The gem has undergone an accepted enhancement of heat treatment to reveal and stabilize its soothing color, a common and permanent process for prasiolite, handled transparently by our team.

Imagine this oval set into a simple bezel to showcase its calm, green blue whisper, or held in a cathedral style prong mount to let light travel through the mixed brilliant facets, creating flashes of pale aqua and sea glass green. On a conscious consumer s wrist or hand it will pair beautifully with recycled metals, with handcrafted settings, and with pieces that emphasize longevity over trend. Because of its size and presence, this 11.75 carat prasiolite becomes a centerpiece, a talisman that speaks of deliberate choices and refined taste.
