Which list are you being given?
July gives the same answer on both lists
Most pages that answer “what is the july birthstone” quote one list without saying which. There are two in common use: the modern American list standardised by the National Association of Jewelers in 1912 and revised since, and the older traditional list that preceded it.
| List | Stone(s) for July | Basis |
|---|---|---|
| Modern | Ruby | Standardised in 1912 and maintained since; used by current gemological guidesThe list this site leads with |
| Traditional | Ruby | Older lists predating the 1912 standardisationUnchanged for this month |
What changed: nothing. July kept Ruby through the 1912 standardisation and every documented revision since, which is why sources agree on it.
The modern list was designed around transparent, faceted gems so that jewellers could set several children's stones in one ring. That commercial motive, not a gemological discovery, is why some months changed. Later revisions added alexandrite and citrine in 1952, tanzanite in 2002, and spinel in 2016.
Neither list is more “correct”: a birthstone assignment is a published convention, not a property of the gem or of the month. If a gift matters, ask which list the recipient grew up with.

Context
