Tanzanites’ mesmerizing color comes from the fact that Tanzanite is trichroic: that is, it shows different colors when viewed in different directions in stones of high clarity. One direction is blue; another is violet, and another red, all that add subtle depths to its color. These colours appear when viewed in different environments and different lighting, and never fail to amaze people. 

The blue and purple hues of tanzanite are associated with generosity and friendship thus making it the perfect gift.
