What is a birthstone?

Definition
A birthstone is a gemstone associated with a particular month of birth, and wearing your birthstone is a tradition that traces back centuries, though the modern standardised lists date mainly from the 20th century. Each month has at least one stone; some months have two or three, because different organisations like the American Gem Society and the Jewellers of America have added alternatives over time. Birthstone jewellery is one of the most personal ways to wear a gemstone, and it makes a meaningful gift for birthdays and milestones.
Frequently asked questions
- What is each month's birthstone?
- January is garnet, February amethyst, March aquamarine, April diamond, May emerald, June pearl or alexandrite or moonstone, July ruby, August peridot or spinel, September sapphire, October opal or tourmaline, November topaz or citrine, and December tanzanite or turquoise or zircon.
- Why do some months have more than one birthstone?
- Different jewellery associations have updated their lists at different times, adding stones that were becoming popular or more affordable. June and December in particular have three stones each, which gives people in those months more choice.
- Can you wear a birthstone that is not yours?
- Absolutely; there is no rule against it. Many people choose a loved one's birthstone to wear as a tribute, or simply pick the stone they like best. The meaning is in what it represents to you.
