Acroite
Tourmaline is said to come in countless colors, and colorless tourmaline is the least well-known of them all.
Its name comes from the Greek word "akhroos," meaning "colorless," and as its name suggests, it is a beautiful, transparent natural stone.
Transparent tourmalines are rare, and in fact there are few completely colorless ones, and they contain a small amount of color. Just as transparent diamonds can also have yellowish or blueish hues, you can enjoy the color tones in the transparency.
