Grandidierite was first discovered in 1902 in Southern Madagascar and was named after a French explorer Alfred Grandidier who studied the natural history of Madagascar. The mineral with bluish-green color can transmit blue, green and white light.



The stone was first described in 1907 by George D. Louderback who named it benitoite for its occurence near San Benito River in San Benito Country, Calofornia. When this blue to purple gemstone is put under UV light, it resembles glowing blue chalk.



This blue-purple gemstone can be found at foothills of Mount Kilimanjaro in Northern Tanzania. It was first discovered by Manuel d’Souza in Merelani Hills of Manyara Region in Northern Tanzania in 1967. The gem is noted for its strong trichroism, appearing alternately blue, violet and burgundy depending on crystal orientation. It can also appear differently when viewed under alternate lighting conditions. Tanzanite could potentially be mined out within 20-30 years, which make it extremely rare and of course, expensive.
