Selenium
3 in the gallery
Selenium is a chemical element that occurs in mineral form only rarely, often found as trace constituents in sulfide and telluride minerals. When seen as crystals, selenium can present a reddish to orange hue with a vitreous to metallic luster and a typically modest crystal habit. Collectors prize specimens from notable sources for their distinctive color and the way selenium can appear in small, well-formed crystals or as inclusions that catch the light.

About Selenium
Among the most accessible example sources are locations in the United States, the Democratic Republic of the Congo, and Mexico, where selenium-bearing minerals or selenium-rich environments have yielded material suitable for display. Specimens are usually small but can be striking when well-formed facets or unique association with other minerals are present, making them appealing to those building a varied suite of elemental or mineralogical curiosities. For collectors, selenium offers a clean, understated aesthetic and a connection to its elemental identity, which can complement more common sulfide and oxide collections.
