Miner becomes overnight millionaire after finding biggest gemstones in history

A miner in Tanzania has become a millionaire after finding the biggest tanzanite gemstones in history.

Tanzanite is one of the rarest gemstones in the world and is only found in northern Tanzania.

Saniniu Lazer discovered the two dark violet-blue gemstones in one of the mines near his home.

He sold the gems to the country's government for an enormous £2.4m.

Lazer says he now plans to party, and then set up small businesses in his area.

The gemstones have a combined weight of 15kg - until now the largest Tanzanite rock to be mined weighed 3.3kg.

The President of Tanzania rang Lazer to congratulate him on his find.

Lazer already has plans on how he'd like to spend his money.

"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."

But first, he said: "There will be a big party."
