HÜBNERITE, QUARTZ

A nice hübnerite specimen formed by several sharp prismatic crystals showing a striated prism and several terminal faces. Its black color and excellent luster offer a very esthetic contrast with the rich quartz crystal matrix. Some hübnerite crystals are transparent on edges and show a deep red color under an intense light. THE MAIN CRYSTAL IS: 1,4 x 0,9 x 0,2 cm.
