Tourmaline is a gemstone well-known for naturally occurring in any shade and saturation of color on the color spectrum. Special terms are assigned to stones of certain colors, such as "rubellite" (red), "indicolite" (blue), "schorl" (black), "dravite" (brown), and "Paraiba" (highly rare electric blue only from Brazil). Occasionally, multiple vivid colors can be present in a single stone, completely independent from one another. These stones are referred to as "bicolor" and "tricolor."
Tourmaline is a hard stone coming in at 7 to 7.5 on the Mohs hardness scale. While stones are safe to use with chemical jewelry cleaner, it is very important to note that tourmaline cannot be put into an ultrasonic cleaner machine. Many tourmalines contain natural liquid-filled inclusions that can burst from ultrasonic vibrations created by such a machine, causing a stone to break. Soap, water, and a soft bristled toothbrush are safe and effective for cleaning tourmaline jewelry.
