Saniniu Lazier,a Tanzanian miner and a father of 30 children, has become a millionaire overnight,after selling two rough Tanzanite stones.The Tanzanite stones sold by Lazier,are the biggest ever find in the country.
Saniniu Laizer made £2.4m ($3.4m) from Tanzania's mining ministry for the gemstones, which had a combined weight of 15kg (33 lb), 9.2kg and 5.8kg.
What is Tanzanite used for?
A lot of people before today,haven't heard the name Tanzanite.Tanzanite is only found in northern Tanzania and is used to make ornaments.
It is one of the rarest gemstones on Earth, and one local geologist estimates its supply may be entirely depleted within the next 20 years.
The precious stone's appeal lies in its variety of hues, including green, red, purple and blue.
Its value is determined by rarity - the finer the colour or clarity, the higher the price.
Mr Laizer mined the stones, weighing 9.2kg and 5.8kg, last week, but he sold them on Wednesday during a trading event in the northern region of Manyara.
Until now the largest Tanzanite rock to be mined weighed 3.3kg.
Saniniu Lazie has now become a big celebrity all over the world.His country,Tanzania's President, John Magufuli phoned in to congratulate him on the find.
"This is the benefit of small-scale miners and this proves that Tanzania is rich," the president said.
Mr Laizer, 52,will have enough things to spend his new millions on.With four wives and 30 children to cater for.He also plans to invest in his community in Simanjiro district in Manyara.
"I want to build a shopping mall and a school. I want to build this school near my home. There are many poor people around here who can't afford to take their children to school."
"I am not educated but I like things run in a professional way. So I would like my children to run the business professionally."
But Lazier said the new windfall would not change his lifestyle, and that he planned to continue looking after his 2,000 cows. He said he did not need to take any extra precautions despite his new-found riches.
"There is enough security [here]. There won't be any problem. I can even walk around at night without any problem."
