Chai means life in hebrew and is symbolized by the number 18. By tradition, 18 is considered good luck, or "long life." In gematria, the letters Het (ח) and Yud (י) add up to the number 18. In Judaism, gifts or donations are commonly given in multiples of 18 as a way of symbolically giving the recipient the gift of Chai, or long life.
Chai circles of life bracelets are made in multiples of 18 beads:
- A single chai contains 18 beads
- A double chai contains 36 beads
- A triple chai contains 54 beads
Chai circle of life bracelets represent good fortune, love, happiness, health, and long life.
