Jagoite is a hexagonal-ditrigonal, dipyramidal, yellow-green lead-silicate mineral consisting of calcium, chlorine, hydrogen, iron, lead, magnesium, oxygen, silicon, and sodium. Its discovery was first published in 1957.[2]
Etymology
It is named after John B. Jago Trelawney, an American mineral collector.[3]
Properties
It is said to have a vitreous (glass-like) lustre.[4]
Jagoite is composed of tiny yellow crystals that span less than 0.2mm.[5]
Distribution
This rare mineral is located in Långban Mine, Långban Ore District, Filipstad, Värmland County, Sweden, found inside hematite ore. It is also associated with Melanotekite and Quartz.[6][7][5]
Media appearances
It is featured in Stardew Valley as a minor item obtained from geodes.
