October is represented by two birthstones, Opal, and Tourmaline, both well known for their color shifting properties. Opal is said to be the stone of innocence, creativity, hope, and inspiration. It is known for its protective properties that it brings to its wearer. Tourmaline brings forth love, compassion, emotional healing, self love, and is regarded for its calming attributes.  Pink tourmaline is the most commonly associated with October birthdays, but Tourmaline comes in a wide array of colors, each coveted for their unique beauty and power.
