Tanzanite Stone: Properties and Characteristics

Tanzanite is a unique gemstone with colors ranging from deep blue to violet. This stone appears more purple in natural light and bluer in fluorescent light, varying according to the lighting conditions. With a Mohs hardness of only 6-7, tanzanite is a relatively soft gemstone, making it more prone to dents and scratches than other gems.

The tanzanite stone is pleochroic, which means that it exhibits various colors depending on the angle at which it is viewed. The tanzanite birthstone also displays a distinctive trichroism, which reveals three different colors depending on the angle from which it is viewed.
