{"product_id":"cassiterite-13","title":"CASSITERITE","description":"A gorgeous weighty cluster of lustrous black metallic Cassiterite crystals from Horn' Slavkov in the Czech Republic.  The specimen is dominated by a large Cassiterite twin, one face of which measures 3.0 x 1.4 cm and beautifully displaying its re-entrant angles.  In good light and when closely examined, the surfaces and edges show translucent patches of typical clove-brown.  There are a few small chips on various edges and some crystals are not complete.  Nevertheless, an eye-catching, chunky and most pleasing group of Cassiterite crystals.
