If your birthday is in October, consider yourself lucky to have two gemstones to choose from. 

Both Opal and Tourmaline are considered official birthstones for October.

Many cultures have credited opal with supernatural origins and powers. Arabic legends say it falls from the heavens in flashes of lightning. The ancient Greeks believed opals gave their owners the gift of prophecy and guarded them from disease. Europeans have long considered the gem a symbol of hope, purity, and truth.
