Tourmaline Fun Facts:
Tourmaline comes in every color of the rainbow. In fact, an Egyptian legend says that in its long passage up from the center of the Earth, tourmaline passed through a rainbow, and collected every color.
Many tourmalines are highly magnetic, with yellow, green and blues able to attract a small magnet. Reds and pinks are generally not very magnetic, however.
The pink color of many tourmalines comes from natural irradiation - as they formed, the crystals were very pale, but exposure to radioactive decay of nearby minerals deepened the color to bright pinks and red.
Watermelon tourmaline (raspberry pink and minty green) from Maine and California took the world by storm in the early 1900’s. The Dowager Empress and Regent of China at the time loved pink tourmaline and imported large quantities from California.
