October

October's child is born for woe,
And life's vicissitudes must know,
But lay an opal on her breast,
And hope will lull those woes to rest.

For October births, the traditional birthstone is opal.  A mysterious stone that can appear milky white or contain irridescent puddles of every color in the rainbow, opal is known to inspire hope and creativity.  The modern stone list includes pink tourmaline as a birthstone for October, which is known to enhance love and happiness.
