Albert Gilg (Technische Universitat Munchen, Germany) used a variety of non-destructive methods (Raman and UV-Vis spectroscopy, and portable EDXRF analysis) to characterize more than 90 rough and 25 faceted gem-quality pyropes from various localities in Bohemia, and compared their properties to pyrope samples from other significant locations worldwide as well as red Cr-poor magmatic pyropes.
For the most part pyrope does not occur in collectible crystals; nevertheless, in "Pyrope from the Dora-Maira Massif" (Gilla Simon) collectors can learn about a geologically unique occurrence in Italy, and in "The Fiery-Eyed Volcanoes of Bohemia" (Jiri Kourimsky and Jaroslay Hyrsl) there's a sketch of the 2,000-year history of mining Bohemian gem pyropes which originate in Tertiary-age volcanic rocks.
