Description
Tourmaline ( /trmln/, -/in/ TOOR-m-lin, -leen) 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.
According to the Madras Tamil Lexicon[3] the name comes from the Sinhalese word thoramalli () or tōra- molli, which is applied to a group of gemstones found in Sri Lanka. According to the same source, the Tamil tuvara-malli () and toramalli are also derived from the Sinhalese root word. This etymology is also given in other standard dictionaries including the Oxford English Dictionary.
