January birthstone
January is one of the months where the four standard lists compared below actually agree: Garnet.
| System | Stone(s) |
|---|---|
| Historical (15th–20th century) | Garnet |
| US 1912 | Garnet |
| UK 2013 | Garnet |
| US current | Garnet |
Source context for each list
- Historical (15th–20th century): This list predates any single standardising body and varied by source, region, and era — it is presented as historical record, not a fixed tradition.
- US 1912: This is a 20th-century commercial standard set by the US jewelry trade in 1912 (later revised in 1952), not an ancient tradition.
- UK 2013: This list was first published by the UK trade body in 1937 and revised in 2013 — a modern commercial standard, not a historical inheritance.
- US current: This is the current US trade list, extended as recently as 2002 (tanzanite) and 2016 (spinel) — an evolving commercial standard, not a fixed tradition.
Why there are four lists at all
None of these four lists was handed down as one unbroken tradition. The historical list predates any formal standard. The US trade first fixed a list in 1912, then revised it in 1952 to add alexandrite, citrine, pink tourmaline, and zircon. The UK's National Association of Goldsmiths set its own list in 1937 and revised it again in 2013, which is why British and American charts still disagree on several months.
Meanwhile, the American Gem Trade Association has kept extending the current US list since then. Tanzanite joined in 2002 and spinel in 2016, so even the newest column here is not finished changing. Treating any one list as "the" birthstone chart quietly picks a winner among several real, dated, competing standards. Comparing all four side by side, as this page does, is the more honest way to answer the question.
Zodiac signs in January
Aquarius and Capricorn fall within January. However, zodiac birthstones follow a separate pair of systems, keyed to the sign rather than the calendar month. Those two systems disagree with each other on every sign, not just some of them. For example, Aquarius's traditional stone is Garnet while its modern trade stone is Amethyst , and Capricorn's traditional stone is Ruby while its modern trade stone is Garnet — the same pattern as the four lists above, for the same reason.
