The Early Days of Tanzanite
In the early 60s, locals were finding scraps of a deep blue crystal throughout the Merelani Foothills of Tanzania. Located at the base of Mt. Kilimanjaro, no one knew the identity of this strange gemstone. Popular tales explain that a Masai tribesman was the first person to discover tanzanite.
These local discoveries were enough to spur prospectors to action. Many would spend long hours inspecting the terrain, searching for a likely source of this blue gem.
Manuel D’Souza registers four claims based on information provided by a Masai tribesman. Initially, he thought that perhaps this would be a promising new source of sapphire. Little did he know that he stumbled onto something more. These initial claims would eventually develop into today’s tanzanite mining operations.
Savvy promotion during the late 60s let tanzanite create a splash early on as designers and jewelers clamored to use this exciting new stone in jewelry. It was something more than a sapphire substitute. It had come into its own due to its captivating colors and unique visual properties.
Modern Tanzanite Mining Operations
The government would reduce small-scale operations in 1990. They divide the tanzanite mine into four separate Blocks, labeling them A, B, C, and D. Blocks A and C go to commercial operations. Small scale mining continues in Blocks B and D.
The largest tanzanite mining firm acquired Block C in 2004. Shop LC is a significant partner in this operation. By working together, we can offer ethically sourced tanzanite gemstones at our daily low cost.
Recently, a wall has been constructed around the mine. The government is cracking down on illegal export of the stone and improving its tax collection process. During this time, mine operations have been severely reduced, drastically limiting the supply of this precious gemstone.
