October is lucky enough to have two birthstones — opal and tourmaline — both famous for their rainbow of colors. One shimmers with iridescent fire, the other comes in nearly every shade imaginable. Here's what October's birthstones mean and how to wear them. (October spans Libra and Scorpio — see their crystal guides too.)
Opal: Creativity & Emotion
Opal is a play-of-color gem believed to amplify creativity, imagination, and emotional expression. Its shifting rainbow flashes have long symbolized inspiration and hope. Because opal is delicate and water-sensitive, it's best kept dry and worn with care.
Tourmaline: Protection in Every Color
Tourmaline comes in an incredible range of colors, each with its own energy. Black tourmaline is the famous protective and grounding stone; pink tourmaline opens the heart; watermelon tourmaline blends love and balance. It's a versatile, protective birthstone for October.
How to Wear October Birthstone Jewelry
October's colorful stones suit playful, expressive pieces. Wear a tourmaline bracelet, choose an iridescent gemstone necklace, or gift a birthstone necklace for an October birthday.
