What is my birthstone?
Each month has a stone and a flower attached to it by long custom. Pick a month to see both, what they are said to represent, and the star signs that share the month.

How it is calculated
- The stones follow the modern list standardised by the jewellery trade in 1912 and revised since, which is the list most shops use today.
- Where a month has more than one stone, all the commonly sold options are listed.
- Birth flowers come from the Victorian language of flowers, which paired each month with one or two blooms.
- The meanings are traditional associations, recorded because people ask for them when buying a gift.
Where this is used in the real world
- Choosing a birthday present, a piece of jewellery or a bouquet.
- Wedding and anniversary planning where stones and flowers are matched to dates.
- Craft and design projects — cards, tattoos, nursery art — keyed to a birth month.
Good to know
- Lists differ by country. The British list keeps a few older stones, and some Asian lists differ again.
- Modern and traditional lists disagree for several months; where they do, both stones are shown.
- The meanings are folklore. They carry no claim about health, luck or protection.
Questions people ask
What is the birthstone for each month?
The full twelve-month list appears in the result, with the flower alongside each stone.
Why does my month have two or three stones?
Trade lists were revised over the last century and some months gained alternatives, usually because the original stone became scarce or expensive.
Are birth flowers the same everywhere?
No. They come from Victorian Britain and vary elsewhere, and some months have a different flower in North American lists.
