October Birthstones - Opal and Tourmaline
Individuals born in October get to choose between two birthstones—tourmaline and opal. Each gem then unveils nearly limitless possibilities, as each one comes in a rainbow of shades and color combinations.
Opal may exhibit a spectrum of colors called play-of-color. When this is set against a dark background, it is known as black opal. Australia is the source of most of the world’s fine opal. Opal represents hope. Tourmaline exhibits a wide range of colors. Bicolored and multicolored crystals are common. Sometimes crystals are green on the outside and pink inside; these are called watermelon tourmalines. Wearing tourmaline is believed to bring strength.
