The rubellite is a particularly beautiful gemstone from the colourful family of the tourmalines. Its colour shines in the most beautiful nuances from red to shocking pink. There are red and pink tourmalines in many nuances, which include a tender pink, a fine shocking pink, an intense violet and a bold ruby-red. However, only a few of these are entitled to call themselves 'rubellites'. The name comes from the Latin 'rubellus', which means reddish. Rubellites are not merely red or shocking pink tourmalines. There is an important criterion for this especially beautiful gemstone, and that is the way its colour behaves in daylight and artificial light. Many gemstones change their colour depending on the light source. A true rubellite does not. It shines just as intensely in artificial light as it does in daylight. The colour of most other pink or red tourmalines, by contrast, displays a more or less clearly visible tinge of brown in artificial light.
