The October Gives you two birthstones: opal and tourmaline, share the place. These two gems are ideal for the zodiac signs Libra and Scorpio.

The beautiful and increasingly rare opal is the birthstone of the zodiac sign Libra. Planet Venus rules this balance-seeking sign, and an opal can help Libra find balance.

Tourmaline is sometimes considered a secondary birthstone, but it is the only stone that can help the intense scorpion master its daily life. As a stone against negative energy, tourmaline can help the scorpion to overcome resentment.
