Treated tanzanite has become the norm, so although it’s undetectable, it’s usually assumed.

The common story of tanzanite’s discovery tells of Maasai herders who found blue crystals in the Merelani Hills near Arusha, Tanzania, while tending livestock in 1967.

They notified a prospector named Manuel d’Souza, who promptly registered claims with the government to begin mining.
