Light interacts dynamically with triangular aquamarines, entering through the table and reflecting off three distinct pavilion areas, creating a unique pattern of brilliance. This trigonal arrangement produces concentrated flashes of light rather than the even sparkle of round cuts. High-quality triangular aquamarines feature precise angles that maximize color saturation while maintaining brightness. The faceting pattern often includes split facets that create additional light play, enhancing the stone’s natural beauty and visual impact in various lighting conditions.
