The authors examine the trade and processing of Bohemian garnets from the 15th to the 18th century, with particular attention to the long-repeated claim that Emperor Rudolf II granted the stonecutters’ brotherhood of Freiburg and Waldkirch an exclusive privilege on 15 July 1601 for the purchase and processing of all Bohemian garnet rough. Drawing on archival documents from Freiburg, Waldkirch, Nürnberg, Vienna, and elsewhere, they trace the development of garnet cutting and trade in Bohemia, Freiburg, Waldkirch, and Nürnberg, and examine Rudolf II’s extensive patronage of gemstone prospecting, cutting, and collecting. The surviving documents demonstrate that imperial privileges were granted to individual gemstone prospectors and craftsmen and that the Freiburg and Waldkirch brotherhood possessed privileges protecting aspects of its trade, but the authors find no original document supporting the supposed 1601 monopoly on Bohemian garnet. Contemporary patents, letters, and petitions instead contradict such an exclusive right. Genuine imperial privileges of 1591, 1653, and 1714 are documented for Nürnberg craftsmen concerning the technique of cutting and attaching Bohemian garnets to glass. The study concludes that although large quantities of Bohemian garnet were indeed shipped to and worked in Freiburg and Nürnberg around 1600, this reflected established commercial relationships and specialized technical skills rather than an imperial monopoly; the familiar “Freiburg garnet privilege” of 1601 is therefore a later interpretation unsupported by the surviving contemporary evidence.
