The Montepuez Ruby Mine in Mozambique is the world’s largest deposit of the highly prized coloured gemstones. One of the most expensive gemstones you can find in Africa, the colour, clarity, cut, and carat weight of a ruby determine its value. The stone is mined and auctioned straight to the market.

There is a lot of money to be gained from exporting rubies. Since 2003, the Burmise Ruby, which was a major export in this gemstone space,  has been banned in the United States. This was part of sanctions aimed at putting pressure on the military regime in Burma, which had neglected democratic elections.

Despite the lifting of restrictions on the Burmese ruby in 2016, the embargo has driven the US-Africa diamond trade.

East Africa, notably Tanzania and Kenya, is home to this stone. Each stone can be cut into three carats, making it incredibly rare. Tsavorite has a primarily higher refractive degree of roughly 1.734/44 when compared to other stones.
