Large beads in fabulous patterns, no two beads the same. These are Tibetan Agate or Dzi stones. Some copper accents pick up the warm tones of the stones. These are natural stones and an acid is applied to bring out the patterns and colors. This is one of the most popular stones I carry for both men and women in browns and grays. Shown here is a hers and his style. The beads are 12mm. This bracelet will fit a big man 9" wrist. Strong and masculine look and feel. The meaning of DZI is "shine, brightness, clearness, splendour" Some people think that Tibetan Agate exudes a energy of power, courage, strength.
