For centuries, gemstones have captivated humanity with their beauty, rarity, and perceived mystical properties. The tradition of associating specific gemstones with each month of the year, known as birthstones, has a rich and evolving history. While the modern list of birthstones is relatively recent, formalized in 1912 by the National Association of Jewelers, the practice of linking gems to specific times of the year dates back to ancient civilizations. Today, birthstones remain a popular and meaningful way to personalize jewelry and connect with one’s birth month. This article provides a detailed overview of the birthstones assigned to each month, exploring their historical context, gemological properties, and cultural significance, based on available information.
Historical Development of Birthstone Lists
The origins of birthstone lists are complex and multifaceted, drawing from various historical and religious sources. Some historians trace the practice back to the New Jerusalem foundation gems mentioned in the Book of Revelation, while others point to the gemstones adorning Aaron’s breastplate as described in the Book of Exodus. These ancient associations between gemstones and spiritual or symbolic meaning laid the groundwork for later birthstone traditions. Early writings from the 1st and 5th centuries A.D., attributed to Flavius Josephus and St. Jerome, established a connection between the breastplate gemstones, the months of the year, and the zodiac signs.
Over time, different cultures developed their own variations of birthstone lists. These lists often reflected the availability of gemstones in specific regions and the prevailing beliefs about their properties. The standardization of birthstones began in the 19th and 20th centuries, with jewelers seeking to create a consistent and marketable system. The National Association of Jewelers’ 1912 list became the foundation for the modern birthstone chart, though it has been updated several times since, most recently in 2016 with the addition of spinel as an August birthstone. The American Gem Trade Association and Jewelers of America have also contributed to these updates.

Some individuals prefer the historical connection of traditional stones, while others are drawn to the wider variety and more recent discoveries represented in the modern list.
