People know Tanzanite for its beauty but not the Tanzanite Mining. It poised lush blue, vibrant violet, and rich purple appearance. Unknown to a lot of people is that gemstone is more sought-after than diamond. This rare stone is only found near majestic Mount Kilimanjaro.
Diz a lenda que esta pedra começou a existir há cerca de 585 milhões de anos, depois das colinas Mererani terem sido incendiadas por um relâmpago. Segundo os homens das tribos Maasai, o efeito do calor sobre os cristais castanhos de zoisite provocou a cor azul dos cristais raros. Os cristais mais procurados do mundo gema foi descoberta por Ndugu Jumanne Ngoma em 1967.
Pouco tempo depois da sua descoberta, Tiffany & Co found out about this new gemstone. They introduced it into the market and attributed a lovely name to it which pays tribute to the land of its birth. This gemstone is hugely sought after, and popular and is the most beautiful stone to be discovered in 2000 years.
A exploração mineira da Tanzanite leva tempo e envolve um processo complexo. Eis como a Tanzanite é minerada:
A Tanzanite é recuperada de veias pegmatites que se tornaram tão estressadas e quebradas em pedaços minúsculos e mais pequenos chamados boudins. Estas pedras preciosas encontram-se dentro de pequenos bolsos dentro dos boudins. O objectivo de Mineração de tanzanite is to find these small pockets. Not every pocket will contain the gem, some might contain minerals such as fool's gold, pyrite, and quartz.
Originalmente, a pedra preciosa era recolhida à superfície, mas a contínua e vigorosa mineração da Tanzanite rapidamente deu lugar a poços e agora túneis que se encontram cerca de 1000 metros abaixo da superfície. Durante o processo de mineração, as rochas são quebradas em pedaços médios ou pequenos, utilizando explosivos como a dinamite.
Loud sounds and ground vibrations are felt from the mining site once the explosives are set off. A big boom is heard and then felt even from far distances. Once this process is done, Oxygen pipes are usually put into the mines to let in the fresh air. These pipes remove the CO2 e trazer O2. O processo seguinte envolve a separação da pedra preciosa das pedras em bruto.
Sorting the gemstone from the other materials can be a daunting task after the Tanzanite Mining. The gemstone can be sorted both manually and by using an automated optical sorting and primary grading system. When sorting the rough tanzanite, several steps are involved before one can achieve a gem worth selling.
O primeiro passo envolve a recolha das gemas do seu poço. Uma vez isso conseguido, as gemas são levadas para a casa de triagem onde são limpas e pesadas. Os materiais não-gem são então removidos das gemas, após o que as gemas são empedradas e classificadas em vários grupos.
Good quality gems are processed more for color, clarity, and carat grading. Once the gems have been graded and sized, they are packed and ready to be sold.
The spare Tanzanite materials are taken back to laboratories by companies. These materials are tested to see if they can be heated to become high-quality gemstones. There are also some minerals that might be found in the Tanzanite stone. Here at Tanzanite Experience, we keep these minerals on display in our museum to educate people about everything Tanzanite.
Tanzania is the world’s largest and only producer of tanzanite. These rare gem deposits are known to be confined to a few square miles of land in northern Tanzania and it is the only gemstone that has a large growing popularity and a limited known supply.
