Tourmaline can be found in Maine, California, South Africa, Afghanistan, and Brazil.


Tourmaline is named from the Sinhalese word turmali, which means “mixed”. It can be found in almost all colors from clear to black with every tone imaginable and with many stones containing more than one color. The most sought form of tourmaline for jewelry is Elbaite, which gradients from pink to green. Watermelon tourmaline, which resembles the colors of the fruit, is considered the Maine State Gemstone. Pink tourmaline is the birtstone of October. 

The gem was found in Brazil in the 1500’s where Spanish conquistadors washed dirt from a green tourmaline crystal, confusing it with emerald. Scientist identified this gemstone species as tourmaline in the 1800’s. One of the earliest reports of tourmaline came in 1892 in California. In the 1800’s Tourmaline became the American gemstone by Tiffany gemologist, George F. Kunz. He praised the stone deposits in Maine and California for the quality of gemstones produced. California’s rich pink tourmaline was shipped to the Chinese Dowager Empress Tzu-Hsi who was fond of the color.

Tourmaline is formed through a hypothermal process, involving water that is undissolved from hot magma. The mixture of water and minerals fill the cracks of magma as it cools and hardens, resulting in tourmaline.

Cleaning & Care

Tourmaline can be easily cleaned at home with warm, soapy water and a soft brush. Ultrasonic or steam cleaners are not recommended for cleaning tourmaline.


Tourmaline is often heat treated or irradiated to enhance color, but many naturally colorful tourmaline gemstones require no treatment.
