colour variations on ivory

Certainly the color of the ivory as it ages is also due in part to the environment in which it ages.

Another piece to the puzzle - sulphur. Exposure to sulphur is what darkens ivory. The more sulphur in the particular environment (or longer exposure) the darker and yellower it becomes.
