Скачать или смотреть Tourmaline; A Gemstone with a Wide Range of Colors

Tourmaline is one of the most common minerals which can be found in certain pegmatites, which is how they receive their name as "tourmaline pegmatites". Yet, tourmaline does not merely occur as a dull black color but also green, reddish-pink, brown, and other color variations. #short #shorts #tourmaline
