Tanzanite is one of the Minerals that was first discovered in Tanzania and is the only source so far. This Gemstone belongs to the Zosite group of minerals with the Chemical formula, calcium Aluminum silicate, which has a hardness of 6.5 to 7. Tanzanite stone is blue and purple in color, but according to the light source, similar to Alexandrite stone, it shows different colors, which is due to the presence of vanadium in it. The dark blue color of tanzanite stone is similar to sapphire, which becomes darker after heating.

Royal Blue Stones in 1970 with low capacities soon attracted the attention of American and European advertisements. When the new gemstone word came out, Henry Platt of the Tiffany Company named the new gemstone tanzanite, and Tiffany began a marketing campaign to introduce it to the public. Currently, tanzanite is the pride of the African country of Tanzania. Of course, after word of this precious stone got out, a deadly attack quickly put an end to the mineral's exploitation. A fake car accident in which D'Souza was killed interrupted the pursuit and extraction of any reserves. As a result, during these two years, the reserves were not able to maintain the demand.
