卡夫拉迪
Switzerland
位于瑞士格劳宾登州图杰奇附近库尔内拉谷的卡夫拉迪,是经典的阿尔卑斯裂隙产地,以石英——尤其扭转状的『螺旋晶』晶癖——为收藏者所推崇。
A classic Alpine cleft locality
Cavradi, in the Tavetsch (Tujetsch) area of Graubünden, is one of the celebrated Swiss Alpine fissure localities, where clefts opened during Alpine metamorphism slowly grew crystals on their walls.
What collectors look for
Cavradi is best known for smoky quartz and the distinctive twisted, table-like "gwindel" quartz habit prized by Alpine collectors, often with chlorite, hematite, and titanite.
