Material: Tourmaline 6mm Inner circumference: Approximately 16.5cm Tourmaline is a popular gemstone for women, also known as the birthstone for October. It has a wide variety of colors, including blue, green, red, pink, black, and colorless, and each color has its own name, such as "Paraiba Tourmaline" and "Indicolite." The state where these various colors of tourmaline are mixed is called candy color (or multi-color, mix color, etc.). Each stone plays a role and helps in various matters and situations, making it a truly all-around power stone. The individual vibrations resonate and amplify each other, exhibiting wonderful power, so the candy color type is recommended for power stone beginners and those who want to know the goodness of tourmaline.
