Tibetan Agate Dzi Beads. Dzi (pronounced Zee) is a Tibetan word used to describe a patterned, usually agate, of mainly oblong, round, cylindrical or tabular shape pierced lengthwise called Heaven's Bead (tian zhu) in Chinese. The meaning of the Tibetan word "Dzi" translates to "shine, brightness, clearness, splendour". The most highly prized dzi beads are made of natural agate and were apparently manufactured in ancient times by an unknown people. Our agate Tibetan Dzi beads are manufactured in China.
