3.23 Ct. Tourmaline from Brazil

Watermelon tourmaline, a unique and fascinating gemstone, is celebrated for its extraordinary beauty and vibrant color transitions, reminiscent of a ripe slice of watermelon. This particular 3.23 carat emerald cut watermelon tourmaline, with dimensions of 11.05 x 6.75 x 4.96 mm, exemplifies the splendor of these naturally occurring gems. It possesses a medium intense color intensity, seamlessly transitioning from a lush green to a delicate pink hue, capturing the visual essence of its namesake fruit.
Originating from the renowned Brazilian gemstone deposits, this watermelon tourmaline is a testament to the geological treasures found in the lush landscapes of Brazil. The formation of watermelon tourmaline dates back millions of years ago during the cooling and crystallization of mineral-rich pegmatite veins. These veins extend deep within the Earth’s crust, subjected to intense pressure and temperature conditions, allowing a myriad of mineral elements to amalgamate and create the stunning color variations observed in watermelon tourmalines.
Tourmaline itself is a complex aluminum borosilicate with a mixed composition that endows it with a fantastical array of colors. What makes watermelon tourmaline inherently special is its characteristic color zoning—a result of trace elements such as manganese and lithium. In chemical terms, this captivating stone can be represented by the crystal formula (Ca,K,Na)(Al,Fe,Li,Mg,Mn)3Al6(BO3)3Si6O18(OH,F)4. The transparent clarity of this particular specimen, with a clarity grade of slightly included when evaluated at eye level, ensures that it refines light brilliantly, accentuated by its excellent polish.
The meticulous emerald cut of this watermelon tourmaline, renowned for its step facets, enhances its natural beauty by highlighting the precise color zonation. The cut not only augments its aesthetic appeal but also demonstrates superior workmanship, expressing attributes of symmetry and proportion that are paramount in gem-cutting. The excellently polished facets provide a sophisticated luster, ensuring that light interaction within the stone is maximized.
For the discerning gemologist or gemstone enthusiast, the allure of this watermelon tourmaline extends beyond mere aesthetics. It offers an intricate view into gemological processes, from the geochemical environments that fostered its birth to the artisan skills involved in its formation and final polish. This 3.23 carat gemstone is not merely an object of beauty, but a chronicle of Earth’s vibrant history, polished and perfected through human ingenuity, ready to be treasured by connoisseurs of geological brilliance.
