Tanzanite was discovered in 1967, just below Mount Kilimanjaro in Tanzania. Still today, this is the only know source or this rare and precious gemstone. Due to this, it is commonly believed that in the years to come this single source of tanzanite will be depleted making the gemstone that much more valuable.
Much of the mysticism of tanzanite is derived from its unique colour. This is in fact a rare characteristic called “pleochrism” which causes the gemstone to portray different shades of violet and blue in different light conditions.
Some people often refer to the stone as being soft. In actual fact, tanzanite has similar characteristics to emeralds and should therefore not be worn during any activities that may cause scratches or chipping. These factors are graded similarly to diamonds, in that a grader will assess the colour, cut, clarity and carat weight of tanzanite in order to determine its value.
