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.
Zodiac signs in January
Aquarius and Capricorn fall within January. Zodiac birthstones are assigned by sign, not by calendar month, under a separate pair of systems that disagree with each other on every sign — see Aquarius and Capricorn for the comparison.
