Rock crystal, limonite – Schynschlucht, Thusis, Viamala, Graubünden, Switzerland
 A sharp-edged rock crystal specimen with a wonderful aesthetic appearance and two barite stars. The rock crystals are covered with a thin layer of limonite, which creates a beautiful color accent and a metallic iridescent sheen.
 This crystal comes from a new find, which was made possible thanks to a one-time special permit. After years of a strict collecting ban, a short-term mining permit was granted. Within the scope of this temporary exception, several specimens were recovered. We are pleased to offer collector pieces from this find.
