Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about your birthstone, this guide will offer you valuable insights into the world of birthstones.
History and Lore of Birthstones
The concept of birthstones dates back thousands of years. One of the earliest known references is found in the biblical Book of Exodus, which mentions the twelve gemstones adorning the High Priest’s breastplate—each believed to represent a different tribe of Israel. These stones were thought to possess divine powers and were used for spiritual guidance and protection.
Over time, the practice evolved. In ancient times, people believed that gemstones could influence the planets and align with the zodiac signs. This led to the development of the modern birthstone system, which is rooted in both historical and cultural traditions.
The first documented birthstone list appeared in a 14th-century manuscript known as the Calendar of the Jews, which associated a gemstone with each month. However, the modern system we recognize today was formalized in the 19th and 20th centuries by organizations such as the American National Association of Jewelers (now Jewelers of America) and the American Gem Trade Association. These groups standardized the list of birthstones, adding new stones as they were discovered or gained popularity.
While the modern list is widely accepted today, some traditional birthstones—like bloodstone for March and opal for October—remain in use by those who prefer the older system. Additionally, some months now have multiple birthstones, reflecting the diversity and availability of gemstones in the modern world.
