From the heart of Brazil where pegmatite veins cooled over eons, this greenish blue tourmaline began as a whisper of color in a mineral world shaped by heat and pressure, and crystalized in pockets rich with iron and copper traces that give it its oceanic hues. At 8.90 carats and measuring 11.83 by 11.78 by 8.70 millimeters, the rough was carefully selected by the gem specialists at The Natural Gemstone Company for its intense color and structural integrity. A thoughtful heat treatment was applied to refine and stabilize the tone, and then an experienced cutter shaped it into a luxurious cushion with a mixed brilliant cut, balancing large luminous facets across the crown and precise pavilion facets to maximize both depth and fire. The result is a transparent gem with a clarity grade of eye clean evaluated at eye level, an excellent polish that sings under light, and an overall presence that feels both bold and refined.
Up close under magnification this tourmaline reveals the microscopic inclusions that make it unmistakably natural, a private landscape that tells its Brazilian origin story. Fine three phase inclusions and minute fluid cavities sit like tiny lagoons within the gem, while delicate needle like mineral inclusions and faint growth zoning trace the rhythm of its formation, capturing light differently as the stone turns and offering a subtle pleochroism that shifts between teal and deeper bluish green. These inclusions are not flaws, they are signatures, they confirm provenance and add an inner life that cannot be replicated by synthetic processes, especially given the gem is eye clean to the naked eye so those signatures remain an intimate secret for the owner and any gemologist who studies it. Set as a statement ring or a centerpiece pendant, its cushion silhouette and mixed brilliant cut will play with light and color, showcasing the intense hue and inner topography that make this stone a singular expression of nature and craft, a piece offered with pride by The Natural Gemstone Company.
