About multicoloured Tourmaline
It’s easy to understand why people so easily confuse tourmaline with other gems: Very few gems match tourmaline’s dazzling range of colours. From rich reds to pastel pinks and peach colours, intense emerald greens to vivid yellows and deep blues, the breadth of this gem’s colour range is unrivalled. Brazilian discoveries in the 1980s and 1990s heightened tourmaline’s appeal by bringing intense new hues to the marketplace.
Tourmalines have a variety of exciting colours with one of the widest colour ranges of any gem.
Tourmaline’s colours have many different causes. It’s generally agreed that traces of iron, and possibly titanium, induce green and blue colours. Manganese produces reds and pinks, and possibly yellows. Some pink and yellow tourmalines might owe their hues to colour centres caused by radiation, which can be natural or laboratory-induced.
The original paraiba tourmaline has a Brazilian source famous for vivid blue to green tourmalines coloured by copper. Paraiba tourmalines are also found in Mozambique and Nigeria.
