Tanzanian small-scale miner Saniniu Kuryan Laizer, 52, poses with two of the biggest of the country’s precious gemstones, Tanzanite, as a millionaire during the ceremony for his historical discovery in Manyara, northern Tanzania, on June 24, 2020. – Laizer found the stones weighing 9.27 and 5.1 kilogrammes respectively in the northern Mirerani hills, an area which President John Magufuli had fenced off in 2018 to stop smuggling of the gem. He sold them to the government for 7.7 billion Tanzanian shillings (nearly $3.3 million/2.9 million euros). The broken biggest record of Tanzanite was 3.5 kilogrammes.
