A very fine loose natural bicolour tourmaline that has been precision cut and finished in the classic Emerald Cut design. This is the perfect design for exquisitely coloured tourmalines that exhibit multiple colours. The tourmaline is yellow at one end and at the other a light blue, the colour transition about even. This beauty is also clean to the eye and the perfect size, shape and proportion for a ring, pendant or other fine piece of jewellery. This is a first class tourmaline and highly recommended.
