Red tourmaline is highly sought after, and only occurs at a few localities world wide. This cab is a cross section of Tourmailine and Quartz.
The name Rubellite comes from the Latin rubellus, meaning “reddish,” and refers to the similarity of its color to that of the Ruby, though most Rubellites are more pink than red. They vary in hue from pale to shocking pink to a bold ruby-red, sometimes with a violet tint. While some in the gem world consider “Rubellite” to be merely a trade name for all deep pink/red Tourmalines, the International Colored Gemstone Association (ICGA) defines the criterion for Rubellites by the way they behave in daylight and artificial light. While many gemstones change color depending on the light source, a true Rubellite shines just as intensely in artificial light as it does in daylight, while other pink or red Tourmalines display a visible tinge of brown in artificial light.
