February has one stone on both lists: amethyst, the purple variety of quartz.
The two lists for February
Modern list (American Gem Society): Amethyst
Traditional list (United Kingdom, National Association of Goldsmiths, 1937): Amethyst
There is no single official birthstone list, so you are free to choose whichever you prefer. You can check any month with our birthstone finder.
About the stones
Amethyst
Amethyst is quartz coloured by iron and natural irradiation, with a hardness of 7. The name comes from the Greek amethystos, “not intoxicated”, and ancient Greek writers linked the stone with sobriety. It fades in strong sunlight, so jewellery is best kept out of a sunny window. See the amethyst guide for more.
How the idea developed
The birthstone idea has two layers: an older tradition of twelve sacred stones and a newer commercial list. In the United States, the 1912 list was adopted by the jewellery trade in Kansas City, in what is now Jewelers of America, to give shoppers a standard reference. Amethyst was already a stone of the church and of royal regalia in Europe, so it had a long history before any list was written.
For the wider history of the idea, see our birthstones overview. The modern list follows the American Gem Society, and the traditional list follows the 1937 United Kingdom list, both summarised in Wikipedia, Birthstone.
A different system
Vedic gemstone (ratna) guidance is a different system from birthstones. It is tied to the nine planets and to a birth chart, not to the calendar month, and it belongs to the Vedic tradition, which is covered on our sister site, Nidarshana Vedh. Nothing on this page is Vedic advice.

Frequently asked questions
↳ Is amethyst the birthstone in every country?
It is on both the modern American and traditional United Kingdom lists. Some other countries keep different lists, so you may see other stones for February elsewhere.
↳ Does amethyst fade?
It can fade in strong, prolonged sunlight, so it is best displayed out of direct sun.
