This one is an excellent Panasqueira specimen. It is formed by a group of prysmatic crystals of Quartz with very good transparency and disposed on matrix. They are accompanied by twinned Cassiterite crystals with very high luster and good size for Panasqueira. This one is an excellent example of Panasqueira Cassiterite suitable for demanding collectors of minerals from this historical mine. In excellent condition.
