Tourmaline is a birthstone for October and is also the gem of the eighth anniversary.
Tourmalines come in a wide variety of exciting colours and very few gems match tourmaline’s dazzling range of colours. From rich reds to pastel pinks and peach, intense emerald greens to vivid yellows and deep blues, this gem’s colour range is unrivalled.The chemical composition is responsible for its colour.
Many tourmaline colour varieties have inspired their own trade names:

Rubellite is a name for pink, red, purplish red, orangy red, or brownish red tourmaline.
Paraíba is a greenish blue, or blue tourmaline from the state of Paraíba, Brazil.
Watermelon tourmaline is pink in the centre and green around the outside.
