bicolor tourmaline

Tourmaline, which is the birthstone for October, refers to those that exhibit two colors in one crystal. There are various combinations such as pink and green, pink and blue, and green and colorless. Each gemstone has its own unique color and balance, so you can enjoy its individuality. Those with pink to red hues surrounded by green hues are called "watermelon tourmalines" because they look similar to watermelons.
