The practice of associating specific gemstones with each month of the year, and consequently with birthdays, is a tradition that has evolved over centuries. While the concept of birthstones dates back to biblical times, the standardized lists we recognize today largely emerged between the 16th and 20th centuries. Initially, the assignment of stones was linked to astrological beliefs and perceived mystical properties, with the intention of bringing good luck, health, and protection to the wearer. The modern birthstone lists, particularly those popularized in the United States in 1912 by the National Association of Jewelers, represent a culmination of historical practices and marketing considerations. This article will explore the history, origins, and symbolism of these cherished gemstones, detailing the current accepted birthstones for each month, as well as acknowledging the traditional variations that persist.
History and Lore
The earliest roots of birthstone association can be traced to the Biblical breastplate of Aaron, described in the Book of Exodus. This ornate garment was adorned with twelve gemstones, each representing one of the tribes of Israel. Over time, these stones became linked to the months of the year, though the specific correspondences varied across cultures and eras. In the 16th century, German and Polish traditions began to connect gemstones with zodiac signs, a practice that initially mirrored the monthly associations but later diverged.
Prior to the 20th century, the selection of a birthstone was often a matter of personal preference, cultural tradition, or religious belief. The availability and cost of gemstones also played a role, with more accessible stones like turquoise and cultivated pearls remaining popular choices even as more exotic gems gained prominence. The standardization of birthstone lists in 1912 by the Jewelers of America aimed to create a more marketable and consistent system, solidifying the modern birthstone chart that is widely recognized today. However, even with this standardization, variations continue to exist, with some months having multiple accepted birthstones – a modern addition alongside the traditional choices.
