A variety of Tourmailine with reasonably saturated dark pink to red colors and medium to dark tones. They make excellent jewellery stones. This ruby-red colored specimen without orange or brown overtones is highly prized.
Brightly colored 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.
