The concept of birthstones—gemstones associated with specific months and their wearers—has captivated people for centuries. These gemstones are more than mere adornments; they carry historical, cultural, and symbolic significance. The assignment of gemstones to months is a complex process shaped by religious texts, ancient traditions, and modern commercial interests. This article explores the origins and evolution of birthstone assignments, focusing on the key institutions and cultural influences that have shaped the modern list.
The Ancient Roots of Birthstones
The origins of birthstones can be traced back to religious and cultural traditions that predate modern gemology. One of the earliest and most influential references comes from the Book of Exodus in the Hebrew Bible. According to this text, the high priest Aaron wore a breastplate adorned with 12 stones, each representing one of the 12 tribes of Israel. This tradition, described in Exodus 28:15–30, is one of the oldest known connections between gemstones and symbolic meaning. The exact identities of these stones have long been a subject of debate among scholars.
Ancient Eastern cultures believed that certain gemstones could influence a person’s fate, health, and spiritual well-being. These beliefs were based on the alignment of celestial forces at the time of a person’s birth. The practice of recommending specific gemstones for specific individuals was an early form of personalized gemstone use, which later influenced the concept of birthstones.
In Western traditions, the idea of assigning gemstones to months and zodiac signs was popularized by scholars such as Flavius Josephus and St. Jerome in the 1st and 5th centuries AD. These scholars associated the 12 stones of the breastplate with the 12 months of the year and the 12 signs of the zodiac. This marked a significant shift in the understanding of gemstones, from symbols of tribal identity to symbols of personal identity and cosmic influence.
By the Middle Ages, the concept of birthstones had further evolved. In some European traditions, gemstones were associated with the 12 apostles of Christianity. For example, Peter was linked to jasper, Andrew to ruby or carbuncle, and James and John to emerald. This practice continued to influence how gemstones were perceived and used throughout the centuries.
The Shift to Monthly Birthstones
Over time, the practice of wearing all twelve stones evolved. By the 8th or 9th century, the tradition had shifted toward something simpler: one gemstone assigned to each month of the year. Some suggest religious leaders may have promoted a more personalized approach to help individuals connect with a single stone that reflected their birth and identity. Of course, practicality likely played a part too, as most people couldn’t afford jewelry featuring twelve different gems.
By the Middle Ages, this idea of a monthly birthstone had spread widely across Europe, particularly in Poland. Ancient symbolism met growing personal sentiment, and the birthstone became a cherished keepsake rather than just a protective object. The tradition of wearing a single gemstone that symbolizes the month of one’s birth is a relatively new custom, traced by mineralogist George Kunz to 18th-century Poland.
Until the twentieth century, the list of birthstones was highly varied and constantly changing over time. The definitive modern birthstone list was established in 1912 by the National Association of Jewelers in the United States. For more than a century, the list has remained mostly unchanged, with the notable exception of the addition of tanzanite as a birthstone for December in 2002. However, the “official” list of birthstones varies from country to country and culture to culture. For example, Britain’s National Association of Goldsmiths made their own birthstone list in the 1930s, which is still in use in Great Britain to this day.
The Standardization of Birthstones in the Modern Era
Despite the long history of gemstone symbolism, the modern list of birthstones was not formally established until the early 20th century. This standardization was driven by commercial interests in the jewelry industry, particularly in the United States. In 1912, the American National Retail Jewelers Association (now known as Jewelers of America) played a pivotal role in defining the official list of birthstones. Their goal was to create a uniform system that could be used across the jewelry trade. The list they established assigned one gemstone to each month of the year. This list was based on a combination of historical references and existing traditions, blending Western and Eastern influences.
The 1912 list included the following assignments:
| Month | Birthstone |
|---|---|
| January | Garnet |
| February | Amethyst |
| March | Aquamarine |
| April | Diamond |
| May | Emerald |
| June | Pearl |
| July | Ruby |
| August | Peridot |
| September | Sapphire |
| October | Opal |
| November | Topaz |
| December | Turquoise |
This list was a significant step toward unifying the concept of birthstones and making them accessible to a wider audience. It also reflected the growing popularity of gemstone jewelry in the early 20th century.
Subsequent modifications to the birthstone list have occurred to reflect newly discovered gemstones, availability, and shifting trends. In 1952, the Jewelry Industry Council of America modified the list, adding alexandrite to June, citrine to November, pink tourmaline to October, and zircon to December. In 2002, tanzanite was added to December's stones. Just as recently as 2016, spinel was added to the month of August.
The Influence of Commercial Interests
The standardization of birthstones in the early 20th century was not solely driven by historical or cultural considerations; it was also a strategic move by the jewelry industry to promote gemstone jewelry as meaningful gifts. The American National Retail Jewelers Association aimed to make birthstone jewelry more marketable by creating a uniform list that could be used across the jewelry trade. This decision was influenced by the growing popularity of gemstone jewelry and the desire to create a standardized system that could be used to market and sell jewelry more effectively.
The 1912 list was designed to be practical for American jewelers, ensuring that the stones chosen would be available in sufficient quantities and at reasonable prices. This approach allowed jewelers to promote birthstone jewelry as meaningful gifts, which could be easily understood and marketed to a wide audience. The list also reflected the cultural and historical traditions that had influenced the concept of birthstones over the centuries, blending Western and Eastern influences to create a list that was both meaningful and marketable.
The Role of Religious and Cultural Traditions
The assignment of gemstones to months was influenced by religious and cultural traditions that had existed for centuries. The breastplate of Aaron in the Book of Exodus provided a foundation for the association of gemstones with symbolic meaning. This tradition was further developed in ancient Eastern cultures, where gemstones were believed to influence a person's fate, health, and spiritual well-being. These beliefs were based on the alignment of celestial forces at the time of a person's birth.

The Significance of Birthstones in Modern Times
The significance of birthstones in modern times extends beyond their historical and cultural roots. Birthstones have become an important part of the jewelry industry, with jewelers and consumers alike valuing the symbolic meaning associated with each gemstone. The standardized list of birthstones has made it easier for jewelers to market and sell jewelry, as customers can easily identify the gemstone associated with their birth month.
The popularity of birthstone jewelry has also been influenced by the growing interest in personalized jewelry. Birthstone jewelry allows individuals to wear a gemstone that is associated with their birth month, creating a personal connection between the wearer and the gemstone. This has led to an increase in demand for birthstone jewelry, with jewelers and consumers alike valuing the symbolic meaning associated with each gemstone.
The significance of birthstones in modern times also reflects the growing interest in gemology and the study of gemstones. The standardized list of birthstones has provided a framework for the study of gemstones, allowing gemologists to study the properties of each gemstone and their association with specific months. This has led to a greater understanding of the properties of gemstones and their association with specific months.
