Throughout history, gemstones have captivated humanity with their beauty and perceived mystical properties. The practice of associating specific gemstones with particular months, known as birthstones, is a tradition steeped in lore and evolving over time. While the precise origins are debated, the concept gained prominence through ancient beliefs and solidified with the standardization efforts of jewelry organizations in the 20th and 21st centuries. This article will explore the fascinating world of birthstones, tracing their historical roots, examining the modern lists, and delving into the significance of these cherished gems.
The earliest connections between gemstones and specific times of the year can be traced back to the Breastplate of Aaron, described in the Book of Exodus. This ornate garment, adorned with twelve stones, was believed to represent the twelve tribes of Israel. In the first century A.D., the Jewish historian Josephus proposed a link between these stones and the twelve signs of the zodiac, laying some of the groundwork for the later association with birth months. However, the widespread connection of gemstones to birth months as we know it today didn’t fully emerge until the 18th century.
The standardization of birthstone lists is a relatively recent development. In 1912, the National Association of Jewelers in the United States adopted an official list, which was subsequently updated by the Jewelry Industry Council of America in 1952. Further refinements continued into the 21st century, with the American Gem Trade Association adding tanzanite as a December birthstone in 2002 and spinel as an additional option for August in 2016. These lists, while providing a modern framework, represent a culmination of centuries of evolving traditions and beliefs. Currently, there are three recognized sets of birthstones: ancient, traditional, and modern, offering a range of options for each month.

Diamonds are sourced from locations like Sri Lanka and Australia, while Tanzanite is exclusively mined in the Merelani Hills of Tanzania.
Symbolism and Significance
Beyond their aesthetic appeal, birthstones are believed to possess unique meanings and powers.

The emotional value associated with birthstone jewelry, particularly when received as a gift, further enhances its significance.
Care and Cleaning
Proper care is essential to maintain the beauty of any gemstone. Considering the hardness of each stone is crucial. Zircon, with a hardness of 6-7.5, requires careful handling, while diamonds, being exceptionally hard, are more durable for everyday wear. Regular cleaning with mild soap and water is generally recommended for most birthstones.
