Why do some months have more than one birthstone?

Modern and traditional lists differ for several months, and some months have official alternates, so you may see two or three stones listed for a single month.

What is the difference between modern and traditional birthstones?

The modern list was standardised in the 20th century (notably the 1912 US list and later updates), while the traditional list reflects older, longstanding associations that vary by region.
