Delightful 100% Natural UNHEATED GREEN TOURMALINE - 0.81ct - Baguette - 10 x 4mm - Nigeria

Tourmaline (TOUR-ma-leen) is a large family of Gemstones with more than 100 hues available. Its name comes from the Sinhalese turmali, meaning mixed Gemstones due to the tendency to confuse Tourmalines with other Gems.
    Tourmaline from Sri Lanka (formerly Ceylon) was first introduced to the Europeans in the late 1600's or early 1700's by Dutch traders. My source for Tourmaline is Sri Lanka (formerly Ceylon), Africa, and Brazil, all known for producing the finest variety of Tourmaline.
    Tourmaline crystals are often cracked and flawed, especially in the Red, Pink and Bi-colors. The Green and Blue colors are generally very clean. Tourmaline is sensitive to strong heat, as this may alter the color, and sudden temperature changes may cause fracturing. It may be prudent to ask a Jeweler to remove the stone before applying his torch. Tourmaline is not usually attacked by chemicals.

TREATMENTS - The vivid colors like Deep Pink to Red in Tourmaline are Heat or Cobalt Irradiation treated to enhance and stabilize the color. This typical treatment process is a permanent process that does not adversely affect the performance and durability of the gemstone, so there's no need to worry when you see this enhancement disclosed.
CARE - Tourmaline is a very good choice for jewelry but it should be stored in a separate compartment or in a jewelry bag to prevent scratching by harder Gemstones. Jewelry featuring Tourmaline is risky if cleaned in an ultrasonic or steam cleaner. I recommend Ionic Cleaners and/or warm, soapy water and a soft brush as the best way to clean Tourmaline jewelry.

The precise colour may vary depending on the specific monitor, the settings and the lighting conditions.
