There is no international standard for birthstones. Lists differ by country and by revision year, which is why published charts disagree.

FAQ
Why do some months have more than one birthstone?
Cost and supply. When a month's stone is rare or expensive, the trade adds affordable alternatives so jewellery remains sellable. Any stone listed for a month counts as that month's birthstone.
Which December birthstone is correct?
All of them. Turquoise was on the original 1912 list, zircon was added in 1952, and tanzanite joined in 2002. Modern US retailers list all three.
Are birthstone lists the same worldwide?
No. The US list comes from the 1912 National Association of Jewelers standard, revised in 1952, 2002 and 2016. Britain's National Association of Goldsmiths issued its own list in 1937, and Japan added ten stones in 2021. There is no international standard.
Which birthstones are durable enough for a ring?
Look at Mohs hardness. Diamond, sapphire, ruby and topaz wear well daily. Opal and pearl are soft and sensitive to moisture, so they suit pendants and earrings better than rings.

Where birthstones come from

The idea traces back to the twelve gems set in the breastplate of the high priest in Exodus. Linking those stones to calendar months came much later, in eighteenth-century Poland, and the list most people use today was adopted in 1912 by the National Association of Jewelers at its Kansas convention.

The list keeps changing

A 1952 revision added alexandrite to June, pink tourmaline to October and citrine to November, and swapped December's lapis lazuli for zircon. The American Gem Trade Association added tanzanite to December in 2002, and spinel joined August in 2016. That is why charts published in different decades disagree — none of them is wrong, they simply reflect different revisions.

National lists differ

Britain's National Association of Goldsmiths published its own standard in 1937, and Japan's jewellery association added ten stones in 2021. There is no international body governing birthstones; each market follows its own trade custom.

Choosing a stone that lasts

Check Mohs hardness before buying a ring. Diamond, ruby, sapphire and topaz hold up to daily wear. Emerald rates highly on hardness but its inclusions make it prone to chipping, and opal and pearl are soft enough that pendants and earrings are the safer setting.
