908g Cubic Pyrite Crystal on Host Rock diopside Weight: 4Beautiful aesthetic pyrite cube Specimen from Spain. The pyrite cubes sit within the natural host rock and display very nicely. This locality's limestone (marl) matrix can dissolve in water, so the specimens matrix needs to stay dry for these pyrite cubes to stay in place.
