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.
In rocks, some mineral species and groups are much more abundant than others; these are termed the rock-forming minerals. The major examples of these are quartz, the feldspars , the micas , the amphiboles , the pyroxenes , the olivines , and calcite; except for the last one, all of these minerals are silicates. [ 39 ]

Avid rock collectors often use their specimens to learn about gemstones, petrology, mineralogy and geology as well as skills in the identification and classifying of specimen rocks, and preparing them for display. The hobby can lead naturally into lapidary projects, and also the cutting, polishing, and mounting of gemstones and minerals. The ...
In geology, particularly in mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles. [ 1 ] [ 2 ] Examples are dolomite , which is an aggregate of crystals of the mineral dolomite , [ 3 ] and rock gypsum , an aggregate of crystals of the mineral gypsum . [ 4 ]

Mineral symbols (text abbreviations) are used to abbreviate mineral groups, subgroups, and species, just as lettered symbols are used for the chemical elements. The first set of commonly used mineral symbols was published in 1983 and covered the common rock-forming minerals using 192 two- or three-lettered symbols. [ 1 ]
