Description: A beautiful 3.52ct Oval Brilliant Cut Bicolor Tourmaline. It has a Yellow/Red Bicolor that is pretty in all types of lighting.
A tourmaline is given the name bicolor when there are at least two separate colors that can be distinguished within the stone.
The color of tourmaline can be caused by many varying factors. Some of which include elements and radiation exposure.
Tourmalines are pyroelectric gemstones. This means that "Tourmaline becomes electrically charged when heated. Also when squeezed: it's piezoelectric too" (gia.edu/tourmaline).
