Natural Topaz Origin


When explorers discovered a precious stone on the small Greek island of Topazios they decided to call it topaz, however, the gem actually turned out to be another precious stone–peridot. Despite the confusion, the name stayed!


First Discovery of Topaz

The first yellow crystals (modern-day topaz stones) were discovered in Germany in 1737, and then in 1740, a large gem was found in Brazil. However, it seems that mix-ups seem to go hand-in-hand with topaz.


The huge stone was originally believed to be a diamond and was quickly fixed in place on the Portuguese crown. The gem was later identified as a topaz rather than a diamond – but kept its place on the royal headwear regardless.


Modern-day Topaz Mining Deposits

Nowadays, topaz can be found in a number of places around the globe, including Pakistan, Afghanistan, Japan, Mexico, Madagascar, Burma, Australia, and the USA. Huge topaz crystals have been found in the past in Ukraine and Brazil.
