Digging for rare gems in Tanzania

Tanzanite, a gemstone found only in northern Tanzania, is 1000 times rarer than diamonds. Discovered 40 years ago, it transforms from reddish-brown to vibrant blue-violet after treatment, boosting its popularity in the US market. The $200 million industry is largely controlled by Tanzanite 1, ensuring worker safety, unlike smaller mines with poor conditions. A tragic accident led to government inspections to improve safety standards, balancing economic benefits with miner safety.
