Prehistoric offers the world’s most beautiful minerals.Read More
World class minerals that meet decorator needs as well as the most prolific of collectors. Prehistoric offers a wide variety of labradorite, pyrite, quartz, red quartz, fluorites and many other specimens including fluorescent minerals, calcite and septarian. We carefully select minerals based on their exceptional color and crystal structure that not only look great but enhance conversation with friends and family. We can source any mineral specimen for any level of collector. We pride ourselves in variety of our pieces. Our lapis lazuli is enhancement free with truly spectacular color. Our amethyst geodes have great intensity of color and beautiful calcite crystals within. Minerals are known to add incredible energy to any home or office.
A mineral is a naturally occurring substance that is different from a rock, which can be an aggregate of minerals or non-minerals, and does not have a specific chemical composition. The study of minerals is called mineralogy. There are over 4,900 known mineral species; over 4,660 of these have been approved by the International Mineralogical Association (IMA). The silicate minerals compose over 90% of the Earth’s crust. The diversity and abundance of mineral species is controlled by the Earth’s chemistry. Silicon and oxygen constitute approximately 75% of the Earth’s crust, which translates directly into the predominance of silicate minerals. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish various species, and these properties in turn are influenced by the mineral’s geological environment of formation. Changes in the temperature, pressure, and bulk composition of a rock mass cause changes in its mineralogy; however, a rock can maintain its bulk composition, but as long as temperature and pressure change, its mineralogy can change as well.
