Share
For centuries, gemstones have been linked with the months of the year, giving rise to the tradition of birthstones. Today, birthstones are among the world's most popular gemstones, appearing in jewellery, gifts, family heirlooms and crystal collections.
Many people choose to wear their birthstone as a personal keepsake, while others simply appreciate its colour, history or traditional symbolism. Although birthstones are often associated with luck, protection or personality traits, these meanings are rooted in cultural traditions and folklore rather than scientific evidence.
Whether you're curious about your own birthstone or looking for the perfect gift, this guide explores every birthstone month, their fascinating history and the traditional meanings associated with each gemstone.
Please note: Birthstone meanings are based on historical traditions, folklore and cultural beliefs. They are symbolic in nature and are not scientifically proven.
What Are Birthstones?
Birthstones are gemstones traditionally associated with each month of the year.
The modern birthstone list most commonly used today was standardised in 1912 by the National Association of Jewelers in the United States, although many cultures have recognised monthly gemstones for centuries before this.
Some months now have multiple accepted birthstones, giving people a choice based on colour, budget or personal preference.
The History of Birthstones
The tradition of birthstones is often linked to the Breastplate of Aaron, described in the Hebrew Bible, which featured twelve precious stones representing the Twelve Tribes of Israel.
Over time, these gemstones became connected with the twelve months of the year and later with the zodiac signs.
Different cultures developed their own birthstone traditions, and lists varied considerably until the modern standard was introduced during the early twentieth century.
Even today, some countries continue to use slightly different birthstone lists.
