Like other precious stones, it is also available in many different colors, mainly green, blue, red, yellow, brown, black, pink, purple, violet, and indigo. These colors are basically due to the presence of traces of magnesium and copper in improper ratios. In addition to its gorgeous color schemes, this stone is known for imparting good health. The best thing about the minerals of tourmaline is that the crystals are found in clean and large forms, which makes them easier to cut and design into impressive faceted pieces of gems.
