According to the Madras Tamil Lexicon[3] the name comes from the word "thoramalli" (තෝරමල්ලි) or "tōra- molli", which is applied to a group of gemstones found in the southern parts of the Indian Subcontinent. According to the same source, the Tamil "tuvara-malli" (துவரைமல்லி) and "toramalli" are also derived from the Sinhalese root word. This etymology is also given in other standard dictionaries including the Oxford English Dictionary.

Brightly colored Ceylonese gem tourmalines were brought to Europe in great quantities by the Dutch East India Company to satisfy a demand for curiosities and gems. Tourmaline was sometimes called the "Ceylonese Sri Lankan Magnet" because it could attract and then repel hot ashes due to its pyroelectric properties.[2][4]
