Fadenquartz (Gwindel?) – Val Cavrein, Graubünden, Switzerland
 Exceptionally aesthetic small specimen from Val Cavrein in the Swiss canton of Graubünden. The rock crystals are all perfectly transparent and highly lustrous. The freestanding spheroid forms a beautiful contrast to the quartz crystals on the matrix. A flawless specimen in terms of structure and quality!
 Clear rock crystal clusters are found less frequently than smoky quartz clusters and are therefore among the most sought-after rarities in alpine collections!
