Tanzanite stone is named after the state of Tanzania; it was discovered in 1967 in the Mererani Hills of Northern Tanzania. Tanzanite is the blue-purple variety of the Zoisite mineral family, imitating sapphire blue, violet, and burgundy, depending on the crystal’s position. Tanzanite is now acknowledged as one of the most popular gemstones in the marketplace after the “big four,” which consists of diamonds, rubies, sapphires, and emeralds.
