This astonishing specimen from Navajún, Spain features a large Pyrite cube with an incredibly unique crystal habit. This rare, completely natural phenomenon grows out of a freestanding Basalt matrix and features unique aesthetics from the inter growth of multiple Pyrite crystals along with geometrically perfect lines and angles and mirror-like luster. While most Pyrite forms a cubic habit, Spanish Pyrite is particularly known for the isolation of its crystals. This truly one-of-a-kind natural art piece will enrich your collection and shine on your shelf.
