October Birthstone - Tourmaline jewellery
The myriad colours of Tourmaline have resulted in it being known as the 'gemstone of the rainbow'. It's colours range from blue to green to pink to yellow, and almost everything in-between!
Not only do Tourmaline's come in many colours, individual stones can also be bi-coloured or even tri-coloured. Perhaps the most well known of these is the Watermelon Tourmaline, so called because of its pink centre and green rim.
