Watermelon Tourmaline Gemstone

Watermelon Tourmaline Gemstone
​
Tourmaline can have coloured zones across the length of the crystal, or they can have a core of one colour and an outer edge of another colour. A single tourmaline can contain up to 15 different colours or shades being nicknamed as the “Rainbow Gem”, gem of October babies. The most popular is bicolor tourmaline is the "watermelon tourmaline." Pink and green colors are found in the same stone, and these colour zones provide a visual record of its formation process. It happens when the trace elements change in concentration or composition during a crystal’s growth.
