What is the birthstone for September?

Sapphire. It is the single recognised stone for the month in the modern list.

Why are there two different September birthstones?

For September the two lists agree, so the question does not arise. Sapphire appears as the September stone in both the traditional associations and the 1912 standardised list. Lists in other countries differ again, so a British, Indian or Japanese list may not match this one.

What colour is the September birthstone?

Sapphire is blue. Natural stones vary considerably in tone and saturation, so two stones of the same type can look quite different, and colour alone is not a reliable way to identify one.
