Here we have a truly outstanding piece from Brazil — a tourmaline crystal measuring over 13 cm. The crystal is beautifully formed and displays a stunning color transition from intense blue through blue-green to green. Even with minimal backlighting, the colors come to life, making this an exceptional crystal of fantastic quality.
