October's birthstone is opal. The month is shared by Libra and Scorpio, holds the festival of Samhain, and its full moon is traditionally the Hunter's Moon.

## Birthstones

Opal shows a play of colour from tiny silica spheres. Tourmaline grows in more colours than almost any other gem. Opalite is a man-made glass, not opal.
