The unique blue-purple tone is the most attractive charm of tanzanite, and the direct lineage of the African jungle further demonstrates the mysterious and exotic flavor of tanzanite. Tanzanite is lucky enough to be among the precious gems as soon as it appears with its unique and elegant hue! Tanzanite belongs to a mineral called Zoisite. Zoisite was not regarded as a gem when it was discovered in 1805, until the blue-purple zoisite (also known as tanzanite) was discovered in Tanzania Just became one of the members of the gem industry. The jewelry industry can only see the trace of tanzanite, and rarely hear the name zoisite.

The 1960s was the era when colored gemstones began to become popular. The prospectors who expedition to Tanzania originally came to search for rubies, but accidentally discovered this beautiful blue-violet gemstone. Di dalam 1968, Tiffany Company introduced a large number of Tanzanite and Started planned marketing. In order to show that it comes from the hometown of the African jungle and add to its mystery, Tiffany named this gemstone Tanzanite after the country where it was discovered.
