History and Lore of Birthstones
The tradition of associating gemstones with months of the year has ancient origins. One of the earliest references to birthstones appears in the biblical Book of Exodus, where the High Priest’s breastplate was adorned with twelve stones, each representing one of the twelve tribes of Israel. Over time, these stones were linked to the months of the year and the zodiac signs.
In the Middle Ages, birthstones were believed to offer protection, bring good fortune, and even cure ailments. For example, the gemstone for April, the diamond, was thought to strengthen the heart and promote love. Similarly, the ruby, the birthstone for July, was believed to protect against disease and bring vitality.
The modern system of birthstones was formalized in the 19th century, with the first official list published in the 1830s by Frederick Schneider, a German mineralogist. The American National Association of Jewelers later revised and expanded this list in the 1950s, adding stones like tanzanite and zircon to reflect the discovery of new gem varieties.
