History and Lore of Birthstones
The concept of birthstones is deeply intertwined with ancient traditions and evolving cultural practices. One of the earliest references to birthstones appears in the biblical Book of Exodus, which describes the 12 stones on the breastplate of the High Priest Aaron. These stones were believed to represent the 12 tribes of Israel, each with its own symbolic meaning. While the exact identities of these stones remain a subject of scholarly debate, their existence marks the beginning of associating gemstones with specific groups or individuals.
The modern system of assigning birthstones to months began to take shape in the 14th century, when the German scholar and physician Johann Kunz first proposed the idea. His work, The Curious Lore of Precious Stones, published in 1917, provided a comprehensive list of birthstones and their properties, which would later influence contemporary lists. However, the United States National Association of Jewelers standardized the list in the 1950s, introducing variations that are still followed today.
This practice of assigning gemstones to months evolved not only as a way of personal identification but also as a means of incorporating symbolic and spiritual meanings into daily life. In many cultures, birthstones were believed to bring protection, good fortune, and even healing. These beliefs have persisted through time, making birthstones a popular choice for meaningful jewelry and gifts.
