The color of Orange or Red Selenite (as with other color variations of the crystal) is caused by the inclusion of minerals. Different minerals will result in different colors and color intensity. Here are some properties of Red Selenite: Red Selenite is sometimes referred to as Red Satin Spar Selenite.
Selenium occurs in minerals such as eucairite (CuAgSe), crooksite (CuThSe) and clausthalite (PbSe), but these minerals are too rare to use as a major source of selenium. Today, most selenium is obtained as a byproduct of refining copper. Selenium's resistance to the flow of electricity is greatly affected by the amount of light shining on it. The brighter the light, the better selenium conducts electricity. This property has made selenium useful in devices that respond to the intensity of light, such as electric eyes, photo cells, light meters for cameras and copiers. Selenium can also produce electricity directly from sunlight and is used in solar cells.
