TOURMALINE

[toor-muh-lin, -leen]

BIRTHSTONE: October 

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

HISTORY: 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. However,  Pink Tourmaline is the official birthstone for the month 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.

FASHION: Want to add a pop of color to your outfit? How about pink or green, or both! What about Watermelon! Tourmaline comes in an array of colors…however, my favorite is pink! Tourmaline is a great stone to pair with jeans and a sweater, or maybe your favorite black dress. Either way, it is going to look great. Tourmaline is also a gemstone that can be worn daily and keep its beautiful shape and color!

FORMATION: 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: Amethyst can be easily cleaned at home with warm soapy water and a soft brush. An ultrasonic cleaner is usually safe to use. Do not use an ultrasonic cleaner when amethyst is dyed or treated by fracture filling.

TREATMENTS: 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.
