Mineral collecting

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. Individual collectors often specialize in certain areas, for example collecting samples of several varieties of the mineral calcite from locations spread throughout a region or the world, or of minerals found in pegmatites. Generally considered the "father of mineralogy", Georgius Agricola (1494–1555) was also an avid mineral collector. He wrote several books, including two of enduring significance: De Re Metallica, an early treatise on mining, and De Natura Fossilium, the first (1546) modern textbook of mineralogy. Another famous 16th century mineral collector was Holy Roman Emperor Rudolf II (1552–1612). He built a large mineral collection while employing Anselmus de Boodt (ca. 1550–1634), his court physician and another avid mineral collector, to expand and tend his collections. 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. Serious collectors will go so far as traveling great distances to find the right specimen. As a collection grows, a collector may become more interested in a particular aspect of mineral collecting. Financial limitations or limitations of physical space can also be motivating factors in specializing a collection. Some specializations include: Species collecting; trying to obtain as many recognized species as possible. A particular locality such as a mine, country, or state/province. A particular mineral species (ex. calcite, quartz, fluorite) or mineral group (zeolites, phosphate minerals) to show the variety within the species/group.
