October babies enjoy a variety of options with their tourmaline and opal birthstones. Both of these gemstones come in a rainbow of shades and color combinations.
Between tourmaline (whose color depends on trace elements in its chemical makeup) and opal (which diffracts light to show a play of multiple colors), October's birthstones offer a full spectrum of gemstones to suit anyone's personal tastes.
Opal
The name “opal” originates from the Greek word opallios, which meant “to see a change in color.”
