Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and comes in wide variety of colors. The name is derived from the Sinhalese word ‘turamali’ which means stone of mixed colors. Tourmaline crystals can range in hue from colorless to black, and from pastel to dark. Tourmaline is also known for having multiple colors within the same stone. Many tourmaline gemstones are cut into long bars, which bring out its best color and highlights its beautiful color zoning.
Gemstones can often have more than one color, and are known as bi-color gems. Bi-color tourmaline gemstones are quite famous and are often sought after by gemstone collectors and jewelry designers.
Tourmaline is usually transparent to translucent. Tourmaline is often included, and most gemstones are typically “Type II’, according to GIA. The level of inclusion varies between the types of tourmalines. Green tourmaline is often eye clean, while blue, red and pink tourmaline, rubellite, paraiba and watermelon tourmaline are almost always significantly included. Rubellite, paraiba and watermelon tourmaline are considered to be Type III clarity gems.
Tourmaline is one of the most important gemstone groups in the world today. What makes tourmaline more special is that this gemstone usually does not require any enhancements. Tourmaline is one of the few gemstones that is known not to be treated in any way.
