Mineral collecting is the hobby of systematically collecting, identifying and displaying mineral specimens. Mineral collecting can also be a part of the profession of mineralogy and allied geologic specialties.
Generally considered the "father of mineralogy" and the "father of mineral collecting" is Georgius Agricola (the Latinized pen name of George Bauer) who was a very learned medical doctor in the Saxon mining towns of Joachimsthal and Chemnitz—who was also an avid mineral collector. He wrote several books, including two of enduring significance: De Re Metallica, an exhaustive treatise on mining, and De Natura Fossilium, the first (1546) modern textbook of mineralogy.
Another famous 16th century mineral collector who brought the topic to the forefront was Holy Roman Emperor Rudolf II (1552–1612), who became very known for his political career such as the Thirty Years’ War (1618–1648), one of the longest and most destructive conflicts in European history, and one of the longest continuous wars in modern history. He also built an enormous collection while employing Anselmus de Boodt (ca. 1550–1634), his court physician, to expand and tend his collections. De Boodt wrote one of the most influential books on the history of gems and minerals: Gemmarum et Lapidum Historia, a book on gems that enormously influenced succeeding generations. After Rudolf's death his collection was dispersed.
Mineral collectors find a variety of reasons to collect minerals. Many minerals are strikingly beautiful and collected for their aesthetic value. Others collect to learn more about mineralogy, the local mining industry and/or local geology. Some simply enjoy exploring the outdoors and socializing and trading with other mineral collectors.
