What is Topaz
Topaz is a kind of Nesosilicate minerals which has a Mohs hardness of 8 that only Diamond, Ruby, and Sapphire is harder than it. Due to impurities in the minerals, Topaz can appear in different levels of yellow, blue, or red. Normally, Topaz without impurities will be colorless or pale blue; with heated treatment, the color will be more vivid. Human formerly had misconceptions about Topaz and was often mixed up Topaz with other gems, but now we can tell the differences by their specific gravity or put them under a microscope.
Legend of Topaz
- Opinions are widely divided about where Topaz got its name. Some said the name cames from an island called Topazios: an ancient Egypt queen was banished to Topazios because she attempted to assassinate Pharaoh. People on the island viewed the queen as fairy descendants and gave her two precious stones, they named the stone Topaz. Although the stones were then confirmed that they are not Topaz and Topazios island does not produce Topaz, either, people still called the very kind of stone Topaz without changing it. Another say is that Topaz comes from a Sanskrit word which means fire.
- Ancient Greek thought Topaz could not only made the ones who was wearing it invisible and escaped from danger but also strengthen their bodies.
- Ancient Egyptian and Roman both believed there was a relation between Topaz and the Sun God, ancient Egyptian even claimed that the radiance of yellow Topaz came from their Sun God, Ra.
