The History of Birthstones

The concept of birthstones has its roots in the Old Testament. Exodus describes the Breastplate of Aaron adorned with twelve jewels representing the twelve tribes of Israel. Biblical scholars later connected these twelve stones with the twelve signs of the Greco-Roman zodiac, creating the first association between gemstones and the time of year. By the eighth and ninth centuries, the stones had also become linked to the Twelve Apostles. The Church encouraged wearing a different stone each month to honor the apostles, reinforcing the connection between gemstones and the calendar months.

These customs shifted and evolved over the centuries, but it wasn’t until 1912 that birthstones were officially standardized. The U.S. Jewelers Association established a list designating one stone for each month. Since then, jewelers have introduced a few alternative stones, but the general list has remained largely the same.
