This is my first dzi bead I ordered three months ago. Though there was a crack in the bead, somehow it does't not change its intended promises it brings.For the last three months, I experienced increase confidence and improved sense of well-being, and hopefully will assume the position of finance section head this year.Right now, I am very excited of the nine-eye dzi bead and it's on the way to be delivered hopefully next week.Thanks Dharmashop for the authentic dzi beads.
