  History and origin The mineral tanzanite or blue zoisite has two stories about the appearance of nuggets on the market . They only agree on one thing — they discovered the stone in 1967 near Kilimanjaro . The origin of the gem is due to rock pressure and high temperatures during the collision at this point of the two continents 580 million years ago . And the name is the country of discovery , Tanzania . Engagement ring A more common version of the story claims that the first copies of the stone were found by a prospector from Portugal , Manuel de Souzo . In the East African state , a man was led to search for rubies . He wandered around the country with an expedition from the local Maasai tribe , until he came across a nondescript brown - purple stone on the Merelani plateau .

 Synthetic stones look and color very similar to natural, but another advantage is their low cost with their expensive counterparts. In the jewelry market, You can easily find synthetic sapphires (the label will indicate "GT" or "C", i.e. synthetic). The question often arises – how do synthetic and artificial sapphires differ from natural ones? How to distinguish a real mineral from an artificially grown one? What are their similarities and differences, how much do the prices of natural and synthetic stones differ? Legend of origin One of the legends of the gem's origin is associated with the Greek God of wine-making Dionysus. Once Dionysus was mad at people for what they have ceased to worship him.

  History and origin Taaffeite became known to the world not so long ago, in the middle of the XX century. In the fall of 1945, Edward Charles Taaffe, a gem researcher, made a startling discovery. At that time, the scientist was working on the study and classification of very rare specimens. During a detailed review of the minerals of the cubic system, he found a sample with obvious differences. Professor of gemology was forced to send the stone to London, in a specialized laboratory for examination of the discovery. After completing the study, the laboratory confirmed that this mineral was indeed unique in its structure. For in-depth analysis, the specimen was sent to the Mineralogy Department of the British Museum. Since the stone was cut, it required the consent of the Irish Earl that a particle of the gem would be cut. After conducting microchemical and x-ray diffraction studies, a result was obtained confirming that the indicators of this sample do not coincide with other gems. Th
