I am selling this crystal cluster mineral specimen of yellow mimetite and calcite from Santa Eulalia, Chihuahua, Mexico. I found it at the Tucson Gem and Mineral show near my home in Tucson, AZ. I hope it finds a good home out there, and I am sure it will. This piece is really beautiful. Thanks so much for visiting my auction and have a great day! The following is information about this mineral from wikipedia: Mimetite is a lead arsenate chloride mineral (Pb5(AsO4)3Cl) which forms as a secondary mineral in lead deposits, usually by the oxidation of galena and arsenopyrite. The name derives from the Greek Μιμητής mimetes, meaning "imitator" and refers to mimetite's resemblance to the mineral pyromorphite. This resemblance is not coincidental, as mimetite forms a mineral series with pyromorphite (Pb5(PO4)3Cl) and with vanadinite (Pb5(VO4)3Cl). Notable occurrences are Mapimi, Durango, Mexico and Tsumeb, Namibia. Contents1Properties2Occurrences3Mimetite specimen gallery4References5External linksProperties Mimetite from NamibiaMimetite is a lead chloride arsenate mineral with the composition Pb5(AsO4)3Cl. It is a secondary mineral, formed by oxidation of primary lead minerals in arsenic-bearing lead deposits.[2] It typically forms short hexagonal crystals that are yellow to brown to orange in color, very brittle, moderately hard (Mohs hardness 3.5-4), and dense (specific gravity 7.24). It is distinctive for its lack of transparency, its resinous to adamantine luster, and its solubility in nitric acid.[5] Mimetite forms a complete solid solution series with pyromorphite, with phosphate (PO3−4) substituting for arsenate (AsO3−4). The two minerals are almost identical in their properties and can be difficult to distinguish except by laboratory tests. Pyromorphite is the more common mineral at most locales.[5] Campylite is a name applied to mimetite or pyromorphite that crystallizes as distinctive barrel-shaped crystals forming curved hemispherical aggregates.[5] Bellite is a name formerly applied to a chromium-bearing mimetite, or possibly a mixture of crocoite, mimetite and quartz, which forms attractive orange red crystals, but has been discredited as a distinct mineral species.[6] OccurrencesMimetite is found in association with lead and arsenic minerals, including pyromorphite, cerussite, hemimorphite, smithsonite, vanadinite, anglesite, pyrite, mottramite, willemite, and wulfenite.[5][2] Good specimens have been reported from Gila County, Arizona, US; Ojocaliente, Zacatecas, Mexico; Cumberland, England; Johanngeorgenstadt, Saxony, Germany; Namibia; and Broken Hill, Australia.[5]
