What Is My Birthstone? Free Birthstone Finder

Your birthstone is the gem traditionally associated with the month you were born. Pick your month, birth date, or zodiac sign in the finder above to see your stone, its colour, and its traditional meaning — along with the stones on both the US modern and UK birthstone lists.

January Garnet, February Amethyst, March Aquamarine, April Diamond, May Emerald, June Pearl, July Ruby, August Peridot, September Sapphire, October Opal, November Topaz, and December Tanzanite. Each of these is on both the US modern list and the UK list published by the National Association of Goldsmiths. See the full chart above for alternative stones and colours.

They come from two lists. The US modern list was first set by the American jewellery trade in 1912 and has been expanded since — Tanzanite was added in 2002 and Spinel in 2016. The UK list is published by the National Association of Goldsmiths (NAG), which first standardised British birthstones in 1937. Every stone the UK list names first for a month is also on the US list, so the differences are in the extra stones: the UK list adds Rock Crystal (April), Chrysoprase (May), Carnelian (July) and Lapis Lazuli (September), while the US list adds Alexandrite (June), Spinel (August), Tourmaline (October) and Zircon (December).

Your birthstone is tied to your calendar birth month, while your zodiac stone follows your astrological star sign, whose dates run across two months (for example Taurus is 20 April to 20 May). Because the two systems line up differently, your month birthstone and zodiac stone can be different gems. Use the By birth date mode above to see both at once.

Yes. There are no rules about only wearing your own birthstone — many people wear a partner's, child's, or parent's stone, or simply choose a colour they love. Birthstone jewellery is one of the most popular personalised gifts precisely because it carries someone's birth month. If you're shopping for someone else, find their month above, then browse matching pieces.

Birthstones actually have biblical roots: the idea is widely traced to the breastplate of Aaron in the Book of Exodus, which held twelve gemstones representing the twelve tribes of Israel. Most people, including many Christians, wear birthstones simply as meaningful jewellery with no religious conflict. Some prefer to focus on the birth-month tradition rather than any astrological meaning. Ultimately it's a personal choice, and wearing a birthstone is not inherently tied to any belief system.

Across many cultures, birthstones have traditionally been associated with qualities such as protection, calm, confidence, and good fortune — for example garnet for friendship or amethyst for clarity. These meanings are part of long-standing tradition rather than proven scientific or medical effects. The real, lasting benefit for most people is owning a piece of jewellery that is personal and meaningful, tied to their own birth month or a loved one's.

Traditional birthstones reflect older, historic associations for each month, while modern birthstones come from standardised lists created for consistency — in the US, the list set by the jewellery trade in 1912 and updated since. Modern lists sometimes add newer or more available gems, which is why the US added Tanzanite in 2002 and Spinel in 2016. The finder above compares two standardised lists side by side: the US modern list and the UK list published by the National Association of Goldsmiths.

Most do. On the UK list published by the National Association of Goldsmiths, every month except January, February and October has an alternative stone — for example Ruby or Carnelian for July, and Tanzanite or Turquoise for December. The US modern list gives March, October and November two stones each, and June, August and December three. Multiple stones give you more colours and price points to choose from for the same month.

Use the By zodiac sign mode above. Each sign has a traditional zodiac stone — for example Capricorn is Garnet and Taurus is Emerald. If you know their exact birth date, the By birth date mode will also show their calendar month birthstone, which is the most common choice for a gift.
