About Bumblebee JasperHide

Formula:
CaCO3
Name:
Trade name.
Trade name for colorful fibrous calcite found at Mount Papandayan, West Java, Indonesia. The material is made of radially grown fibrous calcite with a distinctive yellow, orange, and black banding. The orange and yellow colors are mainly caused by finely dispersed realgar (XRD analysis, Attard and Petrov, 2017; Raman analysis, Fritsch and Ivey, 2015). The black stain is caused by pyrite (EDS analysis, Fritsch and Ivey, 2015).

Note: Bumblebee "Jasper" is a misnomer, as this material contains no quartz at all (while actual jasper is a variety of chalcedony, which itself is more or less a "microcrystalline quartz").
