Tradition
Birthstones
The least mystical item in a birth-fact summary, and often the most quietly loved. A birthstone is a cultural inheritance rather than a calculation — but it is a real one, and it has been attached to your month for a very long time.

Where the custom comes from
The idea is usually traced to the breastplate described in the Book of Exodus, which carried twelve stones for twelve tribes. Over centuries the twelve stones were mapped onto twelve months, and the association stuck. The modern list most jewellers use was standardised in the twentieth century, which is why older sources sometimes disagree with it.
It is worth being straightforward about this: a birthstone is a tradition, not a computation, and it does not do anything. It is included in a birth-fact summary because it is genuinely part of the inheritance attached to the day you were born — and because people like knowing theirs.
