An iconic piece of mid-century German studio design, this sculptural torque bangle bracelet is crafted in solid 925 sterling silver by the renowned Pforzheim workshop of Theodor Klotz (TEKA). The centerpiece features an open, stylized swirl with a smooth brushed face framed by Klotz's signature fine linear reeded outer rim. Floating securely at the interior vortex is a bezel-set, brilliant faceted natural rock crystal (or faceted clear crystal quartz) that captures light with sharp, icy clarity.
