How is tourmaline formed?
Tourmaline is produced in pegmatites. These are voids deep under ground that are filled with a rich hot liquid that is rich in different minerals. When the liquids begin to cool, the minerals crystallize and form Tourmaline crystals. The host rock around these pegmatites is generally granite or schits.
Is tourmaline a strong stone?
Tourmaline ranks 7 to 7.5 on the Mohs scale. Its toughness is considered Fair. Tourmaline is generally stable to light and isn’t affected by exposure to chemicals, but heat can damage a tourmaline. High heat can alter the color, and sudden temperature change (thermal shock) can cause fracturing.
