I bought this stone on my last trip to brazil where i visited the Capao mine in Ouro Preto and was lucky to see a top parcel being dug out.
Imperial topaz: The most sought after of all natural topaz. Its rich golden color is generally not enhanced by any kind of treatment. The most important deposit was found in Minas Gerais, Brazil.Imperial topaz is yellow, pink (rare, if natural) or pink-orange. Brazilian Imperial Topaz can often have a beautiful bright yellow to deep golden brown hue, sometimes even violet. Many brown or pale topazes are treated to make them bright yellow, gold, pink or violet colored. This variety is the most sought-after and highly valued among the topaz gems. Ouro Prêto mines produce orange to pinkish-purple topaz. Often the stone has been confused with the more common citrine (which is made by heating amethyst) found profusely in other Brazilian localities. However, topaz is readily identified by its superior hardness, density, and brilliance, as well as by a pronounced basal cleavage. In the early days topaz was the only gem of importance found near Ouro Prêto. Honoring Brazilian royalty, the gemstone was frequently referred to as “imperial” topaz. Later some sources called it “precious” topaz. Both terms have endured, partly because gem merchants wish to impart to customers the difference between gem topaz and citrine quartz.
