Imperial topaz, with its distinct peach, pink, orange or champagne hues, is the rarest topaz variety. The primary source is the Ouro Preto mines of Minas Gerais, Brazil. Deposits were also found in the Ural Mountains in Russia. In fact Imperial Topaz was named in honor of the Russian monarchy who prized its luxurious golden-sherry hues. Today Imperial Topaz is classified as a very rare Collector Gems. See our Red Imperial Topaz as extremely rare example.

True Imperial Topaz is always untreated, and material which has been colored by artificial means such as irradiation is not regarded as genuine Imperial Topaz.
