The name watermelon tourmaline is given to these beads for its shades of greens and pinks. Tourmaline is the most colorful of all gemstones as you can see in the photo below.
Tourmaline is not a single mineral, but a group of minerals related in their physical and chemical properties. Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors. Depending of the proportions of the various mineral components, Tourmaline may form as red, pink, yellow, brown, black, green, blue or violet. The name Tourmaline comes from an ancient Sinhalese word turmali, meaning "a mixed color precious stone," or turamali, meaning "something small from the earth". The mineral Elbaite is the member of the Tourmaline group and is the most well-known and valuable form of Tourmaline. Elbaite is perhaps the most multicolored mineral, coming in virtually every color of the spectrum. Most of the multicolored Tourmalines and almost all of the Tourmaline gemstones are of the Elbaite variety.
