Ziosite’s most desired variety is a sapphire look-alike, named Tanzanite. It was first discovered in Tanzania back in the 1960s. Tanzanite displays a strong blue to violet to bluish purple hue. It is highly pleochroic, showing a variety of colors depending on the angle they are viewed from. Because it was only discovered about 50 years ago, this fancy gem does not have a long history. Likewise, it’s future remains uncertain because it is only found in one region of the world. One thing is for certain though, this rare beauty continues to command attention and desire. Given at the 24th wedding anniversary, this violet-colored gem is associated with intuition and integrity. It is also said to be the color of wisdom.
