Found exclusively in the East African country of Tanzania, formerly Tanganyika, this exquisite violetish blue gemstone was discovered by Masai herdsmen in 1967. Belonging to the Zoisite family, it was named by Tiffany & Co. and has been one of the most important gemstone finds of recent history. The colour varies from a pale lilac hue through to an intense deep blue, with a slight hint of violet. Because of its hardness, Tanzanite is more suited to necklace, pendant and earring use, though, if shown the respect it deserves, this magnificent gemstone will also work very well as a ring stone. When found in the rough, the crystal displays brown, yellow and violetish blue tones, however, when heat treated, the blue colour intensifies and the brown and yellow hues tend to disappear.
