Extremely rare premium and powerful world's No. 1 high-value dzi bead maker's fine quality dzi bead: Tibetan Old Mine Red Vermilion Turtle Shell Longevity Pattern Vajra Four-Eyed Dzi Bead from a genuine Taiwanese dzi bead production company!! This fine quality dzi bead is made by carefully selecting dzi bead raw materials. Although it became rare in Japan about 15 years ago, it is a very popular and high-value dzi bead among the wealthy in Taiwan and China!! Especially this size is expensive at the wholesale level, making it difficult for dealers to handle, so I think it is very rare!! *Please refer to the photos for the dzi bead size! No. 6S
