Where the modern list comes from

The list most Americans know was adopted in 1912 by the American National Retail Jewelers Association (today Jewelers of America) at a meeting in Kansas City. It was revised in 1952, tanzanite joined December in 2002, and spinel was added to August in 2016.

Other countries keep their own versions. Japan’s list dates to 1958 and gained ten stones in 2021, which is why coral, jadeite and lapis lazuli appear there and not on the US chart. The UK list pairs each month with one main stone and one alternate.

Why some months have more than one stone

Revisions tend to add stones rather than remove them, usually to offer a more affordable or more colorful option. June now has pearl, moonstone and alexandrite; December has turquoise, tanzanite and zircon.

None of a month’s stones outranks the others. Color preference and how the piece will be worn matter more: softer stones like pearl, opal and turquoise scratch and chip more easily than sapphire or diamond.
