Birthstone With Corresponding Zodiac Signs

Birthstone History

Gemstones began having special spiritual meaning and significance since the days of the Old Testament. Described in the book of Exodus, the breastplate of Aaron was worn by the high priest. The breastplate featured 12 gemstones; one for each of the twelve tribes of Israel. 

Later in the 1st and 5th centuries, CE birthstones began being associated with signs of the zodiac. Each stone was thought to grant the wearer special powers during the corresponding astrological period. People would selectively wear each of the twelve gems throughout the course of the year for their purported therapeutic effects. 

The modern birthstones were established in 1912 by the National Association of Jewelers. It was modified from the original birthstones to include only gemstones that could be polished and faceted. This was done to make it easier to create mother’s jewelry that features a birthstone for each child. 

Since 1912 gemstones have occasionally been added, and a few months now have 2 or even 3 birthstones to choose from. The following are all the modern birthstones by month. 

January - Garnet

Garnet was named after pomegranate seeds because of the gemstone’s similar dark red wine coloring. It has been a coveted gemstone since the times of ancient Egypt and is thought to open the heart, ignite love, heighten creativity and inspiration, and promote joy.
