8th - Tourmaline

Tourmaline is a versatile gemstone available in a wide range of colours to match your preference. If you and your partner have different colour preferences, you can even find parti-coloured tourmaline that features two or more colours. One such example is the watermelon tourmaline that combines green and red hues like the colours of a watermelon. Tourmaline can be treated with heat or radiation to enhance its colours, which are permanent.
