Ancient legends say the opal gemstone will soothe away sadness and envy for those with October birthdays. The tourmaline gem also represents the birth month of October with its resistance to breaking and scratching. Both opal and tourmaline gems possess healing and restorative qualities and are symbols of hope, innocence and creativity. Opals strengthen the wearer’s memory and increase the will to live. Tourmaline can relieve stress and increase mental alertness.
