topaz

Topaz is one of the birthstones for November. In addition to yellow, it has many other shades such as blue, colorless, pink, and red. It is broadly divided into two types: common topaz and imperial topaz, with imperial topaz being treated as more valuable. It is a gemstone that has been loved all over the world since ancient times, and legend has it that it was worshiped as a symbol of the sun and gold in ancient Greece and other countries.
