    The Imperial Topaz has colors that range from yellow to red, with pink, orange, rose, and lilac nuances. It generally has few inclusions and is very transparent and shiny. The most common are oval, pear shape (teardrop), stepped facets, etc. It is very rare and, nowadays, is found almost exclusively in Brazil, because the mines in Pakistan no longer produce this gemstone on a large scale and the mines in Russia have been exhausted.
    Density control can easily distinguish the Imperial Topaz from other stones like Morganite, Kunzite, and pink Tourmalines. Compared to the Pink Spinel and pink Corundum, the distinction must be made by checking others properties, such as the refraction rate.
