Birthstones by Month at a Glance

 

What Is a Birthstone?

A birthstone is a gemstone associated with a particular month of the year. Today, people usually wear birthstone jewellery to represent their own birthday, a loved one’s birth month, a child, a family connection or even the symbolism around the stone. This may be in the form of a birthstone necklace, birthstone earrings, a birthstone ring, or even with popular Celtic Jewellery, like the Claddagh ring,

The idea of birthstones is much older than modern birthday jewellery. As early as 1st century AD, scholars connected the 12 coloured gemstones from the biblical Breastplate of Aaron to the 12 months of the year and the zodiac, leading to people wearing the 12 gems and turning them for spiritual protection each month. In India, Vedic astrology was also connected to different gemstones, with written systems like the Navaratna outlined in 5th century texts. 

Across many cultures, gemstones were also worn for qualities people believed they carried, such as protection, strength, love, clarity or calm. Ireland may not have a known ancient birthstone-by-month system, but the Irish do have a rich history of using such jewellery for meaningful adornment, from amber bead necklaces to Connemora Marble encased in family amulets, often representing connections to the natural world. In that sense, modern birthstones continue a much older element of daily life: wearing materials that feel connected to identity, symbolism and memory.
