History and Lore
Ancient Origins
The tradition of associating gemstones with specific months or signs can be traced back to ancient times, particularly in the context of the Biblical Breastplate of Aaron. As described in the Book of Exodus, this breastplate contained twelve stones representing the twelve tribes of Israel. Over time, these stones were interpreted through various cultural and religious lenses, with some historians, like Josephus, suggesting connections between these stones and the months of the year or zodiac signs. St. Jerome, referencing Josephus, later proposed that these stones could also symbolize the Foundation Stones of the New Jerusalem, adding a Christian dimension to the tradition.
Evolution of the Tradition
The practice of assigning a specific stone to each month gained more structure in the medieval period, particularly in the eighth and ninth centuries when religious texts began to associate each apostle with a particular stone. This practice eventually led to the custom of wearing one of twelve stones each month. The tradition of wearing a single birthstone is more recent, with some sources placing its origin in 18th-century Poland, while others, like the Gemological Institute of America, suggest it began in Germany in the 1560s.
Modern Interpretations
The modern list of birthstones was formalized in 1912 by the Jewelers of America, which selected stones primarily based on commercial availability rather than their traditional or zodiacal associations. This list includes well-known gems like garnet, amethyst, aquamarine, and diamond, each with its own unique history and symbolism. The selection of these stones reflects not only their availability but also their cultural and aesthetic appeal, ensuring that each month is represented by a gemstone that is both beautiful and meaningful.
