💠 Birthstone Finder
Find the birthstone for any month or zodiac sign — the modern and traditional gems, their colour, and their meaning — or reverse-look up the month a stone belongs to.
💠 January birthstone
Meaning: Protection, constancy, and enduring friendship.
A gem for every birthday
Birthstones tie a gem to the month — or the star sign — you were born under, a tradition that runs from ancient breastplates of twelve stones to the standardised list jewellers use today. Each stone carries colour and meaning: garnet's protective red for January, the sea-blue calm of March's aquamarine, the royal blue wisdom of September's sapphire.
This finder keeps both the modern and traditional lists so you can honour either, adds the astrological stones for each zodiac sign, and lets you search backwards from a gem to its month. It makes choosing a meaningful, personal piece — a gift or a treat — simple.
❓ Frequently Asked Questions
What is my birthstone?
Pick your birth month and this finder shows the modern and traditional birthstones, their colour, and their symbolism. For example January is garnet, April is diamond, July is ruby, and September is sapphire. Several months have more than one recognised stone.
What's the difference between traditional and modern birthstones?
The modern list was standardised by the US jewellery trade in 1912 and updated since, while traditional birthstones follow older, sometimes centuries-old, associations. Most months agree, but a few differ — March, for instance, is aquamarine on the modern list but bloodstone by tradition.
Do zodiac signs have birthstones too?
Yes. Alongside the calendar-month stones, each astrological sign has its own commonly cited gem — garnet for Capricorn, amethyst for Aquarius, emerald for Taurus, peridot for Leo, and so on. Switch this tool to zodiac mode to see the sign's stone, dates, colour, and meaning.
Why do some months have two or three birthstones?
Availability and taste. June covers pearl, moonstone, and alexandrite; October has opal and tourmaline; December spans tanzanite, zircon, and turquoise. Extra stones were added over the years to offer affordable or more available alternatives, so you can choose the one you like best.
Can I look up which month a gemstone belongs to?
Yes — switch to the reverse lookup and type a stone name. Enter ruby and it returns July; enter aquamarine and it returns March. It matches both the traditional and modern lists, so a stone can map to the month where either list uses it.
