Birthstones are traditionally associated with a month of the year. The origin of birthstones is believed to date back to the breastplate of Aaron which contained twelve gemstones representing the twelve tribes of Israel. The current list dates back to 1912 with only one addition since then – The tanzanite was added to December.
There are numerous legends and myths about birthstone healing power and their therapeutic influence. According to these legends, wearing a gemstone during its assigned month heightened its healing powers. For the full effect, individuals needed to own all twelve and alternate them monthly.
