As you might have guessed from its name, Tanzanite is only found in northern Tanzania at the foot of Mount Kilimanjaro. This Gemstone has a deep purple blue color that distinguishes it from sapphire. Even though its price is not very high compared to the most expensive and luxurious jewels in the world, but be sure that as its resources decrease in the next 20 to 25 years due to the excessive extraction that is taking place now, its price will skyrocket. .

The Great Rift Valley stretches approximately 5,000 km from Syria in Middle east Asia to Mozambique in southern Africa. This rift is slowly but surely splitting Africa in two and is the meeting point of two tectonic plates that have been colliding for millions of years. Volcanic activity here produced Africa's highest peak, Mount Kilimanjaro, and the second largest lake, Tanganyika. Volcanic activity, magma and the subsequent cooled lava have helped form many precious Gemstones and emeralds, rubies, sapphires, garnets, tourmalines and Topaz are just some of those found on this mountain. Once in the past, igneous Rocks containing magma rich in Minerals were mixed and combined with the movement of the continental plates, which finally produced tanzanite gemstones.

In 1990, the Tanzanian government divided the tanzanite mines into four blocks: blocks A, B, C and D. Blocks A and C were awarded to large operators, while blocks B and D were reserved for local miners. In 2005, the government extended the Block C mining lease to TanzaniteOne, which had paid $40 million for its mining lease and license. According to the amount of mining, currently gemologists estimate that the stock of this gem will be exhausted soon. As a result, tanzanite is known as the gem of a generation; Because this generation is the last generation that can buy this gem before it runs out of stock.
