Pharmacosiderite, annabergite, köttigite

Pharmacolite on this sample forms glassy lustrous, prismatic, translucent, and radial aggregates that are present over a large area of the entire specimen. Annabergite occurs here in the form of apple-green, powdery aggregates. These aggregates form a cluster about 0.9 cm in size. Köttigite is found primarily around the edges of the specimen but here it forms beautiful hemispherical pink-colored aggregates. This is a typical and very fine example of secondary arsenic minerals from the locality of Jáchymov.
