Historical Reading List: Red Pyrope Garnets from Bohemia
The Čéske Středohoří highlands of central Bohemia in the Czech Republic have been the source of gem-quality red pyrope garnets for hundreds of years. The region is located about 60 km northwest of Prague. Mining of garnets began in the area in the 16th century, although early European jewelry created a millennium earlier has been found to contain this material. Rock breccias resulting from volcanic eruptions are thought to have been the host of the garnets – these breccias contain fragments of a mantle rock called peridotite (here altered and serpentinized), which appears to have been the original source of the garnet. The pyrope crystals, typically in sizes up to about 6 mm in diameter, is generally recovered as loose grains from sediments that are spread over a large area. The garnets are separated by washing these sediments. At times in the past, vertical shafts were also constructed to access to the garnet rock underground. Much of the garnet production is manufactured for jewelry use in this same area of the country. Bohemian garnet jewelry was especially popular in the 19th century, and is still valued today.
HOW TO USE THIS READING LIST
This reading list was compiled to give you an opportunity to learn more about the history of red pyrope garnets from Bohemia. A number of the articles were published in the 1800s and early 1900s – when many classical gem deposits of historical importance were discovered – and gemology and mineralogy became sciences. The list is presented in chronological order to emphasize the development of ideas over time. The list is not comprehensive, but a compilation of the some interesting gemological information that has often been forgotten or overlooked.
Many of the articles exist in the public domain and can be found online at digital libraries such as Hathitrust, Internet Archive, or other digital repositories. More recent publications can often be found in libraries, including the Richard T. Liddicoat Gemological Library. Abstracts of these articles can usually be found on the website of the original journal or magazine, and the article itself is often available for purchase from the publisher.

Garnets from Bohemia were mentioned by Georgius Agricola, the “father of mineralogy”, in his 1546 work De Natura Fossilisum (Textbook of Mineralogy).
