About the main stone of the jewelry Tanzanite is a mineral that can be considered one of the youngest stones in history - it was discovered in 1967 at the foot of Mount Kilimanjaro. At first, tanzanite was mistaken for sapphire and did not attach any significance to it. Later, studies showed that the blue gem is a type of zoisite stone - a fairly well-known mineral that is not used in jewelry. It is a transparent, fragile and soft mineral. The stone has pleochroism - the ability to change shades depending on the viewing angle. This means that if you look at tanzanite from different sides, the colors will appear different. In daylight, they appear blue, and indoors, they change color to purple. ?880591955
