Topaz is a gemstone belonging to the silicate minerals and is often found in various shades of yellow, brown, green, blue, and pink. The different color variants are typically named according to their color, such as blue topaz, pink topaz, etc. However, there are also special designations in the market, such as Imperial Topaz, London Blue Topaz, and Swiss Blue Topaz.

The name for Imperial Topaz originated in nineteenth-century Russia. At that time, the Ural Mountains were the primary source of topaz, and the pink gemstone extracted there was named after the Russian tsar. Ownership of the gemstone was restricted to the royal family. Today, this color variant of topaz is one of the most valuable.

London Blue Topaz is a specific variant of the topaz family known for its deep, intense blue color. This blue gemstone often exhibits shades of gray and green as well.
