Here is what each result means:

A birthstone is a gemstone associated with the month a person was born. The custom of linking stones to months is ancient, but the version most people know today comes from a standard list published by American jewellers in 1912, which is why it is often called the modern birthstone list. Each month has at least one stone, from garnet in January to turquoise in December.

Birthstones are popular for jewellery and gifts because they add a personal touch. A ring or pendant set with someone's birthstone marks their birth month in a lasting way. Alongside the stones, many cultures also pair each month with a birth flower, giving another traditional way to celebrate a birthday.

It is worth knowing that birthstone lists vary. The modern American list used here is the most common, but older traditional lists, and lists from other countries, sometimes assign a different stone to a month. Several months also have more than one accepted stone, so you may see alternatives elsewhere.

It looks up the stone, flower and meaning for your birth month.

1. Your birth date is read to find the month; the day and year do not matter.
2. The month is matched to its modern birthstone and birth flower.
3. The stone's traditional meaning is shown alongside.

Take a birthday in July.

Result: the birthstone is the ruby, the birth flower is the larkspur, and the ruby traditionally symbolises passion and vitality. An April birthday, by contrast, has the diamond as its stone.

Here is the full modern list used by this calculator.

Some months have popular alternatives: June is also linked to the moonstone and alexandrite, October to the tourmaline, and December to the tanzanite and blue zircon. This calculator shows the most widely used stone for each month.

The stone for a month can depend on which list you use.

The modern list is the most widely used today and is what this calculator follows. Older traditional lists, and lists in other countries, occasionally give a different stone, so a birthstone quoted elsewhere may not always match.

Your Birth Month

The stone and flower depend only on the month, not the day or year of birth.

The List Used

Modern, traditional and regional lists can assign different stones to the same month.

Alternatives

Several months have more than one accepted stone, so a different but valid choice may appear elsewhere.

Gift Ideas

Find the right stone for birthday jewellery or a personalised present.

Curiosity

Look up your own or a friend's birthstone and meaning.

Celebrations

Pair a birthday with its stone and flower for cards or decorations.

1. Using the Day Instead of the Month

Birthstones are set by the month alone, unlike zodiac signs which use the day too.

2. Assuming One Fixed Stone

Several months have more than one accepted stone, so alternatives are normal.

3. Mixing Up Lists

Modern and traditional lists differ for some months, so sources may disagree.

4. Confusing Birthstone and Zodiac Stone

Some traditions link stones to zodiac signs rather than months, which gives different dates.

5. Expecting Scientific Meaning

Birthstone meanings are cultural symbolism, not scientific properties.

The stone and flower follow the widely used modern list for each month.

It is the gemstone linked to your birth month. Enter your birth date and the calculator shows it. For example, July is the ruby and April is the diamond.

January garnet, February amethyst, March aquamarine, April diamond, May emerald, June pearl, July ruby, August peridot, September sapphire, October opal, November topaz, December turquoise.

By month only. Unlike a zodiac sign, which depends on the day too, your birthstone is decided entirely by your birth month.

Because there is more than one list. The modern American list used here is most common, but older traditional and regional lists sometimes assign a different stone.

Yes. June, for example, is linked to pearl, moonstone and alexandrite, and October to opal and tourmaline. This calculator shows the most widely used stone.

A flower traditionally paired with each month, much like a birthstone. July's is the larkspur and June's is the rose, for example.

Each stone carries a traditional symbolic meaning, such as the ruby for passion or the sapphire for loyalty. These meanings are cultural, not scientific.

Not always. Birthstones are tied to calendar months, while some traditions link stones to zodiac signs, which span parts of two months and give different dates.
