Tanzanite is a very rare gemstone that is only found in the country of Tanzania. Originally discovered in 1967. It is found in the Usumburu Mountains that border the Umba Valley of northern Tanzania. Tanzanite occurs in gray, brown, violet, blue, reddish-purple, & green. The gem is interesting because of its exceptional pleochroism. Rotated in different directions a tanzanite will exhibit multiple changes of color. Tanzanite has a low tolerance to ultrasonic cleaning, and should not be cleaned using this method.
