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.

Tourmalines were used by chemists in the 19th century to polarize light by shining rays onto a cut and polished surface of the gem.

The Empress Dowager Tzu-hsi (1835-1908), the last Empress of China, was obsessed with pink tourmaline, and bought virtually the entire production of gem quality material from the mines in San Diego County during the last years of her life.
